Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Operations	1. Organization and Nature of Operations (a) Principal activities XPeng Inc. (“XPeng” or the “Company”) was incorporated under the laws of the Cayman Islands in December 27, 2018, as an exempted company with limited liability. The Company, its subsidiaries and consolidated variable interest entity (“VIE”) and VIE’s subsidiaries (“VIEs”, also refer to VIE and its subsidiaries as a whole, where appropriate) are collectively referred to as the “Group”. The Group designs and develops smart electric vehicles. It delivered its first model of smart electric vehicles, G3, commercially in December 2018. The Group manufactures G3 through strategic collaboration with a third-party vehicle’s manufacturer. The Group delivered its second model of smart electric vehicles, a four-door sports sedan, P7, since May 2020. The Group manufactures P7 through its own manufacturing plant in Zhaoqing. As of December 31, 2019 and 2020, its primary operations are conducted in the People’s Republic of China (“PRC”). (b) History of the Group and Reorganization The Group commenced its operation through Guangzhou Chengxing Zhidong Automotive Technology Co., Ltd. (“Chengxing”) since 2015, Chengxing was founded by Mr. Heng Xia, Mr. Tao He and Mr. Xiaopeng He (collectively the ‘‘Founders’’), and subsequently obtained financing from various third party investors (collectively ‘‘Third Party Investors’’) from 2016 through 2018. In preparation for its IPO, the Group completed a reorganization (the ‘‘Reorganization’’) in September 2019, which involved the following steps: • On December 27, 2018, the Company was established under the laws of the Cayman Islands as an exempted company with limited liability. • On January 7, 2019, XPeng Limited was incorporated in British Virgin Islands as a wholly owned subsidiary of the Company. • On February 21, 2019, XPeng (HK) Limited was incorporated in Hong Kong as a wholly owned subsidiary of XPeng Limited. • On June 21, 2019, Guangdong Xiaopeng Motors Technology Co., Ltd. (‘‘WFOE’’) was established as a wholly owned subsidiary of XPeng (HK) Limited in the PRC. • On September 2019, the Company issued 17,897,478 ordinary shares, 2,021,635 Series A Preferred Shares, 1,859,082 Series A-1 A-2 B-1 B-2 The equity interests held by the existing shareholders in the Company after the Reorganization are the same as the equity interests held by them in Chengxing before the Reorganization. Out of the equity interests issued, 43.44%, 38.09% and 18.47% were in the form of ordinary shares, Preferred Shares and warrants, respectively. Prior to the Reorganization, the shareholders of Chengxing included individual shareholders and institutional shareholders. Pursuant to laws applicable to PRC residents and entities incorporated in the PRC, PRC individuals should complete registration of its outbound investments (i.e. the foreign exchange registration under State Administration of Foreign Exchange (“SAFE”) Circular 37), and PRC institutional investors should complete its statutory filings and foreign exchange registrations for outbound investment (i.e. ODI) respectively, before such PRC residents or entities’ can legally own offshore investments or equity interests in offshore entities. As such, all PRC individual shareholders and PRC institutional shareholders of Chengxing shall complete their relevant registrations and/or statutory filings, as appropriate, before they can, in accordance with applicable PRC laws, hold directly or indirectly the ordinary shares of the Company, which is incorporated under the laws of the Cayman Islands. The warrants are to reflect the holder’s (indirect) rights, obligations and interest in the Company as if the holders are holding Preferred Shares of the Company before the holders complete their necessary registration for outbound investment to exercise their warrants into Preferred Shares of the Company. Once the holders complete the necessary registration for outbound investment, the holders are required to exercise the warrants immediately at a nil price per share. The warrants are transferrable by the holder subject to approval of the Company’s board of directors. Accordingly, the warrants are accounted for and presented based on the terms on the underlying Preferred Shares that the warrants are exercisable into (see Note 19). The shareholders and their respective equity interest in the Company remain the same immediately before and after the Reorganization. Further, the Company, being the holding company after the Reorganization, is a newly established shell company. Accordingly, the Company determined that the Reorganization lacks substance and should be treated as a non-substantive These consolidated financial statements are presented as if the Group Reorganization had already taken place as of the beginning of the period covered by these financial statements. On March 20, 2020, the Company completed a 1:25 share split of all of its ordinary and Preferred Shares of the Company. All shares and per share amounts presented in the consolidated financial statements have been retrospectively adjusted to reflect the share split. In August and December 2020, the Company completed its IPO and FO on the New York Stock Exchange (“NYSE”) (Note 20). As of December 31, 2020, the Company’s principal subsidiaries and VIEs are as follows: Place of incorporation Date of incorporation or acquisition Equity Principal activities Principal subsidiaries Chengxing (1) PRC January 09, 2015 100 % Investment holding Guangzhou Xiaopeng Motors Technology Co., Ltd.(Xiaopeng Technology) PRC May 12, 2016 100 % Design and technology development Guangzhou Xiaopeng Automobile Manufacturing Co., Ltd.

Consequently, WFOE became the primary beneficiary of Chengxing. In May 2020, Guangdong Xiaopeng Motors Technology Co., Ltd exercised its rights under the contractual arrangement and purchased 100% of Chengxing. Consequently, Chengxing became an indirect wholly owned subsidiary of XPeng Inc. Place of incorporation Date of incorporation or acquisition Economic interest held Principal activities VIEs Guangzhou Zhipeng IoV Technology Co., Ltd.(Zhipeng IoV) PRC May 23, 2018 100 % Ride-hailing services and operating the related mobile app Guangzhou Yidian Zhihui Chuxing Technology Co., Ltd.(Yidian Chuxing) PRC May 24, 2018 100 % Mobile apps and providing value-added services (c) Variable interest entity Zhipeng IoV was established by two shareholders of the Company (the “Zhipeng IoV’s Nominee Shareholders”) in May 23, 2018. In May 28, 2018, Xiaopeng Technology, Zhipeng IoV, and Zhipeng IoV’s Nominee Shareholders entered into a series of contractual agreements, including an equity interest pledge agreement, a loan agreement, exclusive service agreement, exclusive call option agreement and power of attorney that irrevocably authorized Xiaopeng Technology to exercise the equity owner’s rights over Zhipeng IoV. These agreements provide the Company, as the only shareholder of Xiaopeng Technology, with effective control over Zhipeng IoV to direct the activities that most significantly impact Zhipeng IoV’s economic performance and enable the Company to obtain substantially all of the economic benefits arising from Zhipeng IoV. Management concluded that Zhipeng IoV is a variable interest entity of the Company and the Company is the ultimate primary beneficiary of Zhipeng IoV and shall consolidate the financial results of Zhipeng IoV in the Group’s consolidated financial statements. As of December 31, 2020, Zhipeng IoV did not have significant operations, nor any material assets or liabilities. Yidian Chuxing was established by two shareholders of the Company (the “Yidian Chuxing‘s Nominee Shareholders”) in May 24, 2018. In May 28, 2018, Guangzhou Xiaopeng Zhihui Chuxing Technology Co., Ltd, (“Xiaopeng Chuxing”), Yidian Chuxing, and Yidian Chuxing‘s Nominee Shareholders entered into a series of contractual agreements, including an equity interest pledge agreement, a loan agreement, exclusive service agreement, exclusive call option agreement and power of attorney that irrevocably authorized Xiaopeng Chuxing to exercise the equity owner’s rights over Yidian Chuxing. These agreements provide the Company, as the only shareholder of Xiaopeng Chuxing, with effective control over Yidian Chuxing to direct the activities that most significantly impact Yidian Chuxing’s economic performance and enable the Company to obtain substantially all of the economic benefits arising from Yidian Chuxing. Management concluded that Yidian Chuxing is a variable interest entity of the Company and the Company is the ultimate primary beneficiary of Yidian Chuxing and shall consolidate the financial results of Yidian Chuxing in the Group’s consolidated financial statements. As of December 31, 2020, Yidian Chuxing did not have significant operations, nor any material assets or liabilities. (d) Liquidity The Group has been incurring losses from operations since inception. The Group incurred net losses of RMB1,398,823 , RMB3,691,673 and RMB2,731,985 for the years ended December 31, 2018, 2019 and 2020, respectively. Accumulated deficit amounted to RMB6,824,503 and RMB11,322,423 as of December 31, 2019 and 2020, respectively. Net cash used in operating activities was approximately RMB1,572,715, RMB3,562,765 and RMB139,766 for the years ended December 31, 2018, 2019 and 2020, respectively. The Group’s liquidity is based on its ability to enhance its operating cash flow position, obtain capital financing from equity interest investors and borrow funds to fund its general operations, research and development activities and capital expenditures. The Group’s ability to continue as a going concern is dependent on management’s ability to execute its business plan successfully, which includes increasing market acceptance of the Group’s products to boost its sales volume to achieve economies of scale while applying more effective marketing strategies and cost control measures to better manage operating cash flow position and obtaining funds from outside sources of financing to generate positive financing cash flows. In August and December 2020, with the completion of its IPO and FO on NYSE, the Group received the net proceeds of RMB11,410,386 and RMB15,988,903, respectively. As of December 31, 2020, the Group’s balance of cash and cash equivalents, restricted cash, excluding RMB35,585 restricted as to withdrawal or use for legal disputes, short-term deposits and short-term investments was RMB35,306,556. Management has concluded, after giving consideration to its plans as noted above, the net proceeds received upon completion of IPO and FO, and existing balance of cash and cash equivalents as of December 31, 2020, that the Group has sufficient funds for sustainable operations and it will be able to meet its payment obligations from operations and debt related commitments for the next twelve months from the issuance of the consolidated financial statements. Accordingly the consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities during the normal course of operations.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies (a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) to reflect the financial position, results of operations and cash flows of the Group. Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below. (b) Principles of consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries and the VIEs for which the Company is the ultimate primary beneficiary. All transactions and balances among the Company, its subsidiaries and VIEs have been eliminated upon consolidation. A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power: has the power to appoint or remove the majority of the members of the board of directors (the “Board”): to cast majority of votes at the meeting of the Board or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. A VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, bears the risks of, and enjoys the rewards normally associated with, ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity. In determining whether the Company or its subsidiaries are the primary beneficiary, the Company considered whether it has the power to direct activities that are significant to the VIE’s economic performance, and also the Company’s obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIEs that could potentially be significant to the VIEs. (c) Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, mezzanine equity and related disclosures of contingent assets and liabilities at the balance sheet date, and the reported revenues and expenses during the reported period in the consolidated financial statements and accompanying notes. Significant accounting estimates reflected in the Group’s consolidated financial statements primarily include, but are not limited to, the determination of performance obligations and allocation of transaction price to those performance obligations, the determination of warranty cost, lower of cost and net realizable value of inventory, assessment for impairment of long-lived assets and intangible assets, recoverability of receivables, valuation of deferred tax assets, determination of share-based compensation expenses as well as redemption value of the Preferred Shares. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates. (d) Functional currency and foreign currency translation The Company uses Renminbi (“RMB”) as its reporting currency. The functional currencies of the Company and its subsidiaries which are incorporated in United States or in Hong Kong are United States dollars (“US$”), while the functional currencies of the other subsidiaries and VIEs in the Group are RMB. The determination of the respective functional currency is based on the criteria set out by ASC 830, Foreign Currency Matters. Transactions denominated in currencies other than in the functional currency are translated into the functional currency using the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are translated into functional currency using the applicable exchange rates at the balance sheet date. Non-monetary re-measured The financial statements of the Group’s entities of which the functional currency is not RMB are translated from their respective functional currency into RMB. Assets and liabilities denominated in foreign currencies are translated into RMB at the exchange rates at the balance sheet date. Equity accounts other than earnings generated in current period are translated into RMB at the appropriate historical rates. Income and expense items are translated into RMB using the periodic average exchange rates. The resulting foreign currency translation adjustments are recorded in other comprehensive loss in the consolidated statements of comprehensive loss, and the accumulated currency translation adjustments are presented as a component of accumulated other comprehensive loss in the consolidated statements of total shareholders’ (deficit) equity. (e) Convenience translation Translations of balances in the consolidated balance sheets, consolidated statements of comprehensive loss and consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2020 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.5250 as set forth in the H.10 statistical release of the U.S. Federal Reserve Board. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2020, or at any other rate. (f) Fair value Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Group considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability. The Group applies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This guidance specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows: Level I — Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured. Level II —Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level II valuation techniques. Level III —Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The fair value guidance describes three main approaches to measure the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. Financial assets and liabilities of the Group primarily consist of cash and cash equivalents, restricted cash, short-term deposits, short-term investments, accounts receivable, financial lease receivables, other assets, accounts and notes payable, short-term borrowings, lease liabilities, accruals and other liabilities and long-term borrowings. As of December 31, 2019 and 2020, the carrying values of these financial instruments, except for other non-current non-current Financial assets that are measured at fair value on a recurring basis consist of short-term investments and derivative assets. All of its short-term investments and derivative assets, which are comprised primarily of structured deposits, bank financial products and a forward exchange contract, are classified within Level II of the fair value hierarchy because they are floating income products linked to currency exchange rate, gold and benchmark interest rate. They are not valued using quoted market prices, but can be valued based on other observable inputs, such as interest rates and currency rates. The group has derivative liabilities that are measured at fair value. The derivative liabilities are used to account for the redemption right that met the definition of a derivative and are classified within level III at the fair value hierarchy as the Company adopted the equity allocation model with unobservable inputs for which there little or no market data to determine the fair value. (g) Cash and cash equivalents Cash and cash equivalents represent cash on hand, time deposits and highly liquid investments placed with banks or other financial institutions, which are unrestricted as to withdrawal and use, and which have original maturities of three months or less. Cash and cash equivalents as reported in the consolidated statement of cash flows are presented separately on the consolidated balance sheet as follows: As of December 31,2019 As of December 31,2020 Amount RMB equivalent Amount RMB equivalent Cash and cash equivalents: RMB 772,435 772,435 4,428,120 4,428,120 US$ 167,732 1,168,754 3,793,451 24,781,268 HKD 6,418 5,742 — — Total 1,946,931 29,209,388 As of December 31, 2019 and 2020, substantially all of the Group’s cash and cash equivalents were held in reputable financial institutions located in the PRC, Hong Kong and the United States. (h) Restricted cash Restricted cash primarily represents bank deposits for letter of credit, bank notes and a forward exchange contract amounted to RMB425,812 and RMB2,296,560 as of December 31, 2019 and 2020, respectively. And deposits, amounted to RMB35,000 and RMB35,585, that are restricted due to legal disputes as of December 31, 2019 and 2020, respectively. (i) Short-term deposits Short-term deposits represent time deposits placed with banks with original maturities between three months and one year. Interest earned is recorded as interest income in the consolidated statements of comprehensive loss during the years presented. As of December 31, 2020, substantially all of the Group’s short-term deposits amounting to RMB979,897 are placed in a reputable financial institution in PRC. (j) Current expected credit losses In 2016, the FASB issued ASU No. 2016-13, The Group’s accounts receivable, other current assets and finance lease receivables are within the scope of ASC Topic 326. The Group has identified the relevant risk characteristics of its customers and the related receivables, other current assets and finance lease receivables which include size, type of the services or the products the Group provides, or a combination of these characteristics. Receivables with similar risk characteristics have been grouped into pools. For each pool, the Group considers the historical credit loss experience, current economic conditions, supportable forecasts of future economic conditions, and any recoveries in assessing the lifetime expected credit losses. Other key factors that influence the expected credit loss analysis include customer demographics, payment terms offered in the normal course of business to customers, and industry-specific factors that could impact the Group’s receivables. Additionally, external data and macroeconomic factors are also considered. This is assessed at each quarter based on the Group’s specific facts and circumstances. For the year ended December 31, 2020, the Group recorded RMB10,039 expected credit loss expense in selling, general and administrative expenses. As of December 31, 2020, the expected credit loss provision for the current and non-current The Group typically does not carry significant accounts receivable related to vehicle sales and related sales as customer payments are due prior to vehicle delivery, except for amounts of vehicle sales in relation to government subsidy to be collected from government on behalf of customers. Other current assets primarily consist of other receivables. Financial lease receivables primarily consist of the aggregate of the minimum lease receivable at the inception of the lease and the initial direct costs. The Group recorded a provision for current expected credit losses. For the Year Ended December 31, 2020 Balance as of December 31, 2019 4,645 Adoption of ASC Topic 326 2,074 Balance as of January 1, 2020 6,719 Current period provision 10,039 Write-offs (4,251 ) Balance as of December 31, 2020 12,507 Allowance for the accounts receivable, other current assets and finance lease receivables recognized for the year ended December 31, 2019 was 3,812, nil and 833. (k) Short-term investment For investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Group elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in fair values are reflected in the consolidated statements of comprehensive loss. The Group’s short-term investments in financial instruments were RMB407,844 and RMB2,820,711 as of December 31, 2019 and 2020, respectively. (l) Inventory Inventories are stated at the lower of cost or net realizable value. Cost is calculated on the standard cost basis and includes all costs to acquire and other costs to bring the inventories to their present location and condition, which approximates actual cost on monthly weighted average method. The Group records inventory write-downs for excess or obsolete inventories based upon assumptions on current and future demand forecasts. If the inventory on hand is in excess of future demand forecast, the excess amounts are written off. The Group also reviews inventory to determine whether its carrying value exceeds the net amount realizable upon the ultimate sale of the inventory. This requires the determination of the estimated selling price of the vehicles less the estimated cost to convert inventory on hand into a finished product. Once inventory is written-down, a new, lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Inventory write-downs of RMB109,505 and RMB92,612 were recognized in cost of sales for the years ended December 31, 2019 and 2020. (m) Property, plant and equipment, net Property, plant and equipment are stated at cost less accumulated depreciation and impairment loss, if any. Property, plant and equipment are depreciated primarily using the straight-line method over the estimated useful life of the asset. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful lives, which range from two to ten years, of the related assets. Salvage value rate is determined to 0% based on the economic value of the property, plant and equipment at the end of the estimated useful lives as a percentage of the original cost. Estimated useful lives Buildings 20 years Machinery and equipment 5 to 10 years Charging infrastructure 5 years Vehicles 4 to 5 years Computer and electronic equipment 3 years Others 2 to 5 years Depreciation for mold and tooling is computed using the units-of-production The cost of maintenance and repairs is expensed as incurred, whereas the cost of renewals and betterment that extends the useful lives of property, plant and equipment is capitalized as additions to the related assets. Construction in progress represents property, plant and equipment under construction and pending installation and is stated at cost less accumulated impairment losses, if any. Completed assets are transferred to their respective asset classes and depreciation begins when an asset is ready for its intended use. Interest expense on outstanding debt is capitalized during the period of significant capital asset construction. Capitalized interest expense on construction-in-progress The gain or loss on the disposal of property, plant and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statement of comprehensive loss. The loss on the disposal of property, plant and equipment amounting to RMB30,275, RMB1,191 and RMB6,167 were recognized in operating expenses during the years ended December 31, 2018, 2019 and 2020, respectively. (n) Intangible assets, net Intangible assets consist of manufacturing license, license plate, software and license of maintenance and overhauls. Intangible assets with finite lives, including software and license of maintenance and overhaul, are carried at acquisition cost less accumulated amortization and impairment, if any. Finite lived intangible assets are tested for impairment if impairment indicators arise. Amortization of intangible assets with finite lives are computed using the straight-line method over the estimated useful lives as below: Estimated useful lives Software 2 to 10 years License of maintenance and overhauls 26 months The estimated useful lives of intangible assets with finite lives are reassessed if circumstances occur that indicate the original estimated useful lives have changed. Intangible assets that have indefinite useful life were manufacturing license and license plate as of December 31, 2020. The Group evaluates indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support indefinite useful lives. The value of indefinite-lived intangible assets is not amortized, but tested for impairment annually or whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. (o) Land use rights, net Land use rights are recorded at cost less accumulated amortization. Amortization is provided on a straight-line basis over the estimated useful lives which are 50 years that represent the terms of land use rights certificate. (p) Impairment of long-lived assets Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will affect the future use of the assets) indicate that the carrying amount may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment by comparing carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. Fair value is determined using anticipated cash flows discounted at a rate commensurate with the risk involved. (q) Warranties The Group provides a manufacturer’s standard warranty on all vehicles sold. The Group accrues a warranty reserve for the vehicles sold by the Group, which includes the Group’s best estimate of the projected costs to repair or replace items under warranties and recalls when identified. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Group’s relatively short history of sales, and changes to the Group’s historical or projected warranty experience may cause material changes to the warranty reserve in the future. The portion of the warranty reserve expected to be incurred within the next 12 months is included within accruals and other liabilities, while the remaining balance is included within other non-current The Group considers the standard warranty is not providing incremental service to customers rather an assurance to the quality of the vehicle, and therefore is not a separate performance obligation and should be accounted for in accordance with ASC 460, Guarantees. The Group also provides extended lifetime warranty embedded through a vehicle sales contract. The extended lifetime warranty is likely incremental service provided to the customer to differentiate with other peer companies, as such, the lifetime warranty is a separate performance obligation distinct from other promises and should be accounted for in accordance with ASC 606. (r) Revenue recognition Revenue is recognized when or as the control of the goods or services is transferred upon delivery to customers. Depending on the terms of the contract and the laws that apply to the contract, control of the goods and services may be transferred over time or at a point in time. Control of the goods and services is transferred over time if the Group’s performance: • provides all of the benefits received and consumed simultaneously by the customer; • creates and enhances an asset that the customer controls as the Group performs; or • does not create an asset with an alternative use to the Group and the Group has an enforceable right to payment for performance completed to date. If control of the goods and services transfers over time, revenue is recognized over the period of the contract by reference to the progress towards complete satisfaction of that performance obligation. Otherwise, revenue is recognized at a point in time when the customer obtains control of the goods and services. Contracts with customers may include multiple performance obligations. For such arrangements, the Group allocates overall contract price to each distinct performance obligation based on its relative standalone selling price in accordance with ASC 606. The Group generally determines standalone-selling prices for each individual distinct performance obligation identified based on the prices charged to customers. If the standalone selling price is not directly observable, it is estimated using expected cost plus a margin or adjusted market assessment approach, depending on the availability of observable information, the data utilized, and considering the Group’s pricing policies and practices in making pricing decisions. Assumptions and estimations have been made in estimating the relative selling price of each distinct performance obligation, and changes in judgments on these assumptions and estimates may affect the revenue recognition. The discount provided in the contract are allocated by the Group to all performance obligations as conditions under ASC 606-10-32-37 When either party to a contract has performed, the Group presents the contract in the consolidated balance sheet as a contract asset or a contract liability, depending on the relationship between the entity’s performance and the customer’s payment. A contract asset is the Group’s right to consideration in exchange for goods and services that the Group has transferred to a customer. A receivable is recorded when the Group has an unconditional right to consideration. A right to consideration is unconditional if only the passage of time is required before payment of that consideration is due. If a customer pays consideration or the Group has a right to an amount of consideration that is unconditional, before the Group transfers a good or service to the customer, the Group presents the contract liability when the payment is made or a receivable is recorded (whichever is earlier). A contract liability is the Group’s obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. The Group’s contract liabilities are primarily resulted from the multiple performance obligations identified in the vehicle sales contract, which is recorded as deferred revenue and recognized as revenue based on the consumption of the services or the delivery of the goods. Vehicle sales The Group generates revenue from sales of electric vehicles, together with a number of embedded products and services through a contract. The Group identifies the customers who purchase the vehicle as its customers. There are multiple distinct performance obligations explicitly stated in a series of contracts including sales of vehicle, free charging within 4 years or 100,000 kilometers, extended lifetime warranty, option between household charging pile and charging card, vehicle internet connection services, and services of lifetime free charging in XPeng-branded super charging stations and lifetime warranty of battery which are accounted for in accordance with ASC 606. The standard warranty provided by the Group is accounted for in accordance with ASC 460, Guarantees, and the estimated costs are recorded as a liability when the Group transfers the control of vehicle to a customer. Car buyers in the PRC are entitled to government subsidies when they purchase electric vehicles. For efficiency purpose and better customer service, the Group or Zhengzhou Haima Automobile Co., Ltd. (“Haima Auto”) applies for and collect such government subsidies on behalf of the customers. Accordingly, customers only pay the amount after deducting government subsidies. The Group determined that the government subsidies should be considered as part of the transaction price because the subsidy is granted to the buyer of the electric vehicle and the buyer remains liable for such amount in the event the subsidies were not received by the Group due to the buyer’s fault such as refusal or delay of providing application information. The overall contract price is allocated to each distinct performance obligation based on the relative estimated standalone selling price. The revenue for sales of the vehicle and household charging pile is recognized at a point in time when the control of the vehicle is transferred to the customer and the charging pile is installed at customer’s designated location. For vehicle internet connection service, the Group recognizes the revenue using a straight-line method. For the extended lifetime warranty and lifetime warranty of battery, given limited operating history and lack of historical data, the Group decides to recognize the revenue over time based on a straight-line method initially, and will continue monitoring the cost pattern periodically and adjust the revenue recognition pattern to reflect the actual cost pattern as it becomes available. For the free charging within 4 years or 100,000 kilometers and charging card to be consumed to exchange for charging services, the Group considers that a measure of progress based on usage (rather than a time-based method) best reflects the performance as it’s typically a promise to deliver the underlying service rather than a promise to stand ready. For the services of lifetime free charging in XPeng-branded super charging station, the Group recognize the revenue over time based on straight-line method during the expected useful life of the vehicle. Initial refundable deposits for intention orders and non-refundable XPILOT, the Group’s autonomous driving system, provides assisted driving and parking functions tailored for driving behavior and road conditions in China. The Group plans to roll out XPILOT 3.0 in January 2021. A customer can subscribe for XPILOT 3.0 by either making a lump sum payment or paying annual installments for a three-year period. XPILOT 3.0 will feature several new functions, including a navigation guided pilot for highway driving and advanced automated parking. Revenue related to XPILOT 3.0 is recognized at a point in time when autonomous driving functionality of XPILOT 3.0 is activated and transferred to the customers. Other services The Group provides variable other services to customers including services embedded in a sales contract, supercharging service, maintenance service, ride hailing services and vehicle leasing service. Services embedded in a sales contract may include free charging within 4 years or 100,000 kilometers, extended lifetime warranty, option between household charging pile and charging card, vehicle internet connection services, lifetime warranty of battery and services of free charging services in XPeng-branded charging station. Other services also include supercharging service and maintenance service. These services are recognized under ASC 606. The Group provides ride hailing services with smart commuting solutions to customers by using the Group’s self-owned G3 vehicles and hiring and training drivers managed by third party agents via service agreement. The Group believes it acts as a principle in the ride hailing services as it controls a specified good or service before it is transferred to the customers. The revenue for ride hailing services is recognized overtime in a period when the ride hailing services is consumed under ASC 606. Revenue from vehicle leasing service to customers under operating lease and finance lease are recognized under ASC 842. Practical expedients and exemptions The Group follows the guidance on immaterial promises when identifying performance obligations in the vehicle sales contracts and concludes that lifetime roadside assistance, traffic ticket inquiry service, courtesy car service, on-site Considering the qualitative assessment and the result of the quantitative estimate, the Group concluded not to assess whether promises are performance obligation if they are immaterial in the context of the contract and the relative stand-alone fair value individually and in aggregate is less than 1% of the contract price, namely the lifetime roadside assistance, traffic ticket inquiry service, courtesy car service, on-site Customer Upgrade Program In the third quarter of 2019, due to the upgrade of the latest vehicle model, G3 2020, the Group voluntarily offered all owners of G3 2019 model the options to either receive loyalty points, valid for 5 years since the grant date, which can be redeemed for goods or services, or obtain an enhanced trade-in As both options provide a material right (a significant discount on future goods or services) for no consideration to existing customers with unfulfilled performance obligations, the Group considers this arrangement to be a modification of the existing contracts with customers. Further, as the customers did not pay for the additional rights, the contract modification is accounted for as the termination of the original contract and commencement of a new contract, which will be accounted for prospectively. The material right from the loyalty points or the trade-in For the material right from loyalty points, the Group estimated the probability of points redemption when determining the stand-alone selling price. Since the fact that most merchandise can be redeemed without requiring a significant amount of points compared with the amount of points provided to customers, the Group believes it is reasonable to assume all points will be redeemed and no forfeiture is estimated currently. The amount allocated to the points as a separate performance obligation is recorded as a contract liability (deferred revenue) and revenue will be recognized when future goods or services are transferred. The Group will continue to monitor forfeiture rate data

Concentration Risk [Abstract]
Concentration and Risks	4. Concentration and Risks (a) Concentration of credit risk Assets that potentially subject the Group to significant concentrations of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term deposits and short-term investment. The maximum exposure of such assets to credit risk is their carrying amounts as of the balance sheet dates. As of December 31, 2019 and 2020, substantially all of the Group’s cash and cash equivalents, restricted cash, and short-term investments were placed with the PRC and international financial institutions. Management chooses these institutions because of their reputations and track records for stability, and their known large cash reserves, and management periodically reviews these institutions’ reputations, track records, and reported reserves. Management expects that any additional institutions that the Group uses for its cash and bank deposits would be chosen with similar criteria for soundness. Bank failure is uncommon in PRC and the Group believes that those Chinese banks that hold the Group’s cash and cash equivalents, restricted cash, short-term deposits and short-term investments are financially sound based on publicly available information. (b) Foreign currency exchange rate risk The revenues and expenses of the Group’s entities in the PRC are generally denominated in RMB and their assets and liabilities are denominated in RMB. The Group’s oversea financing activities are denominated in U.S. dollars. The RMB is not freely convertible into foreign currencies. Remittances of foreign currencies into the PRC or remittances of RMB out of the PRC as well as exchange between RMB and foreign currencies require approval by foreign exchange administrative authorities and certain supporting documentation. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	5. Fair Value of Financial Instruments ASC 820, Fair Value Measurements, states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. The three-tiered fair value hierarchy, which prioritizes which inputs should be used in measuring fair value, is comprised of: (Level I) observable inputs such as quoted prices in active markets; (Level II) inputs other than quoted prices in active markets that are observable either directly or indirectly and (Level III) unobservable inputs for which there is little or no market data. The fair value hierarchy requires the use of observable market data when available in determining fair value. Assets and liabilities that were measured at fair value on a recurring basis were as follows: As of December 31, 2019 As of December 31, 2020 Fair Value Level I Level II Level III Fair Value Level I Level II Level III Short-term investments 407,844 — 407,844 — 2,820,711 — 2,820,711 — Derivative assets – a forward exchange contract — — — — 105,183 — 105,183 — Derivative liabilities – Preferred Shares (i) 897,091 — — 897,091 — — — — (i) In determining the fair value of derivative liabilities, the Company has adopted the equity allocation model. For purposes of determining the redemption right of Series A, A-1 A-2, B-1 B-2, re-performed A-1 A-2, B-1 B-2, A-1 A-2, B-1 B-2, Valuation Date December 2 and December 31, 2019 April 10, 2020 May 11, 2020 May 26, 2020 June 30, 2020 July 31, Volatility (1) 37.90 % 42.38 % 42.82 % 42.69 % 41.75 % 43.20 % Risk-free rate (2) 2.65 % 1.10 % 1.05 % 1.03 % 0.97 % 1.38 % Dividend yield (3) 0.00 % 0.00 % 0.00 % 0.00 % 0.00 % 0.00 % Time to expiration (4) 5.37 5.02 4.93 4.89 4.8 4.71 (1) The volatility is estimated based on the historical share price movement of comparable companies for the period of time close to the expected time to exercise. (2) The risk-free rate is based on the market yield of US treasury curve with China country risk premium. (3) The dividend yield is estimated by the Company based on its expected dividend policy over the contractual term of the options. (4) Time to expiration is the time between valuation date and the redemption or liquidation date.

Vehicles represent the rides-qualified vehicles operated by the Group for the ride hailing services, certain vehicles under operating lease arrangement with customers and the vehicles used for the Group’s daily operation. Construction in progress primarily consists of the construction of Zhaoqing manufacturing plant and mold, tooling, machinery and equipment related to the manufacturing of the Group’s vehicles. During the years ended December 31, 2018, 2019 and 2020, the Group capitalized RMB1,907, RMB38,483 and RMB26,351 of interest, respectively. Subsidies for interest expenses capitalized received from government by the Group were recognized to reduce the interest expenses capitalized in the construction of Zhaoqing manufacturing plant. Subsidies for interest expenses received from government by the Group were recognized to reduce the interest expenses after completion of construction. In April 2020, the completed assets are transferred to their respective assets classes. The accumulated impairment loss was RMB79,185 and RMB135,467 as of December 31, 2019 and 2020, primarily due to the phasing out of G3 2019 model in 2019 and upgrade of G3 2020 model in 2020.

Total future amortization expenses for finite-lived intangible assets were estimated as follows: 2021 22,982 2022 19,327 2023 17,098 2024 16,691 2025 8,384 Thereafter 372 Total 84,854 (i) Acquisition and subsequent sale of the 100% equity interest in a company that holds a manufacturing license On March 12, 2020, the Group entered into a share transfer agreement (the “STA”) to acquire the 100% equity interest in a company (the “Acquiree”) from its shareholders (the “Sellers”) for a total cash consideration of RMB510 million (the “Acquisition”). In March 2020, as part of the equity purchase, all of the Acquiree’s net assets with a carrying value of RMB8 million which included the manufacturing license were acquired by the Group under the terms of the STA, subject to regulatory approval. In accordance with the STA, on June 6, 2020, immediately after approval from the relevant PRC regulatory authority was granted for the manufacturing license to be transferred from the Acquiree to the Group, the Group sold its 100% equity interest in the Acquiree to the Sellers’ related parties for consideration of RMB16 million, resulting in a sale of all of the Acquiree’s net assets, except for the manufacturing license. Given the acquisition from the Sellers and the subsequent sale to the Sellers’ related parties were in accordance with the terms of the STA, the consideration received of RMB16 million, in substance, represents an adjustment or reduction to the total cash consideration of RMB510 million incurred by the Group for the manufacturing license. The net effect of the series of transactions outlined above is that only the manufacturing license was acquired and retained by the Group. The Group determined that it was the nominee shareholder of the Acquiree during the period from acquisition to the sale of the Acquiree after regulatory approval was obtained for the transfer of the manufacturing license to the Group, approximately three months. During this period, the Group was not entitled to any of the economic results of the Acquiree. In accordance with ASC 810, the Group did not obtain a controlling financial interest in the Acquiree during this period, and accordingly, did not consolidate the financial statements of the Acquiree. The Acquisition is determined to be an asset acquisition as the Group did not obtain a controlling financial interest in the Acquiree upon closing of the Acquisition in May 2020. On the basis above, the Group accounted for the acquisition of the manufacturing license as an intangible asset with a total cost of RMB494 million. The useful life of the license is assessed as indefinite as there is no limit to the valid period of the license under the relevant PRC laws and regulations. Out of the initial cash consideration of RMB510 million, RMB100 million was paid in December 2019, RMB100 million was paid in March 2020, RMB100 million was paid in April 2020, RMB100 million was paid in July 2020 and RMB110 million was paid in August 2020. For the repurchase consideration of RMB16 million due from the Sellers’ related parties, RMB10 million was received in June 2020 and 6 million was received in November 2020.

In addition to the services condition, employees are also required to provide continued service through the satisfaction of the occurrence of Liquidity Event that occurs within seven or ten years after the vesting commencement date.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of presentation	(a) Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) to reflect the financial position, results of operations and cash flows of the Group. Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below.
Principles of consolidation	(b) Principles of consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries and the VIEs for which the Company is the ultimate primary beneficiary. All transactions and balances among the Company, its subsidiaries and VIEs have been eliminated upon consolidation. A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power: has the power to appoint or remove the majority of the members of the board of directors (the “Board”): to cast majority of votes at the meeting of the Board or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. A VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, bears the risks of, and enjoys the rewards normally associated with, ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity. In determining whether the Company or its subsidiaries are the primary beneficiary, the Company considered whether it has the power to direct activities that are significant to the VIE’s economic performance, and also the Company’s obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIEs that could potentially be significant to the VIEs.
Use of estimates	(c) Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, mezzanine equity and related disclosures of contingent assets and liabilities at the balance sheet date, and the reported revenues and expenses during the reported period in the consolidated financial statements and accompanying notes. Significant accounting estimates reflected in the Group’s consolidated financial statements primarily include, but are not limited to, the determination of performance obligations and allocation of transaction price to those performance obligations, the determination of warranty cost, lower of cost and net realizable value of inventory, assessment for impairment of long-lived assets and intangible assets, recoverability of receivables, valuation of deferred tax assets, determination of share-based compensation expenses as well as redemption value of the Preferred Shares. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.
Functional currency and foreign currency translation	(d) Functional currency and foreign currency translation The Company uses Renminbi (“RMB”) as its reporting currency. The functional currencies of the Company and its subsidiaries which are incorporated in United States or in Hong Kong are United States dollars (“US$”), while the functional currencies of the other subsidiaries and VIEs in the Group are RMB. The determination of the respective functional currency is based on the criteria set out by ASC 830, Foreign Currency Matters. Transactions denominated in currencies other than in the functional currency are translated into the functional currency using the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are translated into functional currency using the applicable exchange rates at the balance sheet date. Non-monetary re-measured The financial statements of the Group’s entities of which the functional currency is not RMB are translated from their respective functional currency into RMB. Assets and liabilities denominated in foreign currencies are translated into RMB at the exchange rates at the balance sheet date. Equity accounts other than earnings generated in current period are translated into RMB at the appropriate historical rates. Income and expense items are translated into RMB using the periodic average exchange rates. The resulting foreign currency translation adjustments are recorded in other comprehensive loss in the consolidated statements of comprehensive loss, and the accumulated currency translation adjustments are presented as a component of accumulated other comprehensive loss in the consolidated statements of total shareholders’ (deficit) equity.
Convenience Translation	(e) Convenience translation Translations of balances in the consolidated balance sheets, consolidated statements of comprehensive loss and consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2020 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.5250 as set forth in the H.10 statistical release of the U.S. Federal Reserve Board. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2020, or at any other rate.
Fair value	(f) Fair value Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be either recorded or disclosed at fair value, the Group considers the principal or most advantageous market in which it would transact, and it also considers assumptions that market participants would use when pricing the asset or liability. The Group applies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This guidance specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows: Level I — Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured. Level II —Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level II valuation techniques. Level III —Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The fair value guidance describes three main approaches to measure the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. Financial assets and liabilities of the Group primarily consist of cash and cash equivalents, restricted cash, short-term deposits, short-term investments, accounts receivable, financial lease receivables, other assets, accounts and notes payable, short-term borrowings, lease liabilities, accruals and other liabilities and long-term borrowings. As of December 31, 2019 and 2020, the carrying values of these financial instruments, except for other non-current non-current Financial assets that are measured at fair value on a recurring basis consist of short-term investments and derivative assets. All of its short-term investments and derivative assets, which are comprised primarily of structured deposits, bank financial products and a forward exchange contract, are classified within Level II of the fair value hierarchy because they are floating income products linked to currency exchange rate, gold and benchmark interest rate. They are not valued using quoted market prices, but can be valued based on other observable inputs, such as interest rates and currency rates. The group has derivative liabilities that are measured at fair value. The derivative liabilities are used to account for the redemption right that met the definition of a derivative and are classified within level III at the fair value hierarchy as the Company adopted the equity allocation model with unobservable inputs for which there little or no market data to determine the fair value.
Cash and cash equivalents	(g) Cash and cash equivalents Cash and cash equivalents represent cash on hand, time deposits and highly liquid investments placed with banks or other financial institutions, which are unrestricted as to withdrawal and use, and which have original maturities of three months or less. Cash and cash equivalents as reported in the consolidated statement of cash flows are presented separately on the consolidated balance sheet as follows: As of December 31,2019 As of December 31,2020 Amount RMB equivalent Amount RMB equivalent Cash and cash equivalents: RMB 772,435 772,435 4,428,120 4,428,120 US$ 167,732 1,168,754 3,793,451 24,781,268 HKD 6,418 5,742 — — Total 1,946,931 29,209,388 As of December 31, 2019 and 2020, substantially all of the Group’s cash and cash equivalents were held in reputable financial institutions located in the PRC, Hong Kong and the United States.
Restricted cash	(h) Restricted cash Restricted cash primarily represents bank deposits for letter of credit, bank notes and a forward exchange contract amounted to RMB425,812 and RMB2,296,560 as of December 31, 2019 and 2020, respectively. And deposits, amounted to RMB35,000 and RMB35,585, that are restricted due to legal disputes as of December 31, 2019 and 2020, respectively.
Short-term deposits	(i) Short-term deposits Short-term deposits represent time deposits placed with banks with original maturities between three months and one year. Interest earned is recorded as interest income in the consolidated statements of comprehensive loss during the years presented. As of December 31, 2020, substantially all of the Group’s short-term deposits amounting to RMB979,897 are placed in a reputable financial institution in PRC.
Current expected credit losses	(j) Current expected credit losses In 2016, the FASB issued ASU No. 2016-13, The Group’s accounts receivable, other current assets and finance lease receivables are within the scope of ASC Topic 326. The Group has identified the relevant risk characteristics of its customers and the related receivables, other current assets and finance lease receivables which include size, type of the services or the products the Group provides, or a combination of these characteristics. Receivables with similar risk characteristics have been grouped into pools. For each pool, the Group considers the historical credit loss experience, current economic conditions, supportable forecasts of future economic conditions, and any recoveries in assessing the lifetime expected credit losses. Other key factors that influence the expected credit loss analysis include customer demographics, payment terms offered in the normal course of business to customers, and industry-specific factors that could impact the Group’s receivables. Additionally, external data and macroeconomic factors are also considered. This is assessed at each quarter based on the Group’s specific facts and circumstances. For the year ended December 31, 2020, the Group recorded RMB10,039 expected credit loss expense in selling, general and administrative expenses. As of December 31, 2020, the expected credit loss provision for the current and non-current The Group typically does not carry significant accounts receivable related to vehicle sales and related sales as customer payments are due prior to vehicle delivery, except for amounts of vehicle sales in relation to government subsidy to be collected from government on behalf of customers. Other current assets primarily consist of other receivables. Financial lease receivables primarily consist of the aggregate of the minimum lease receivable at the inception of the lease and the initial direct costs. The Group recorded a provision for current expected credit losses. For the Year Ended December 31, 2020 Balance as of December 31, 2019 4,645 Adoption of ASC Topic 326 2,074 Balance as of January 1, 2020 6,719 Current period provision 10,039 Write-offs (4,251 ) Balance as of December 31, 2020 12,507 Allowance for the accounts receivable, other current assets and finance lease receivables recognized for the year ended December 31, 2019 was 3,812, nil and 833.
Short-term investment	(k) Short-term investment For investments in financial instruments with a variable interest rate indexed to the performance of underlying assets, the Group elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in fair values are reflected in the consolidated statements of comprehensive loss. The Group’s short-term investments in financial instruments were RMB407,844 and RMB2,820,711 as of December 31, 2019 and 2020, respectively.
Inventory	(l) Inventory Inventories are stated at the lower of cost or net realizable value. Cost is calculated on the standard cost basis and includes all costs to acquire and other costs to bring the inventories to their present location and condition, which approximates actual cost on monthly weighted average method. The Group records inventory write-downs for excess or obsolete inventories based upon assumptions on current and future demand forecasts. If the inventory on hand is in excess of future demand forecast, the excess amounts are written off. The Group also reviews inventory to determine whether its carrying value exceeds the net amount realizable upon the ultimate sale of the inventory. This requires the determination of the estimated selling price of the vehicles less the estimated cost to convert inventory on hand into a finished product. Once inventory is written-down, a new, lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Inventory write-downs of RMB109,505 and RMB92,612 were recognized in cost of sales for the years ended December 31, 2019 and 2020.
Property, plant and equipment, net	(m) Property, plant and equipment, net Property, plant and equipment are stated at cost less accumulated depreciation and impairment loss, if any. Property, plant and equipment are depreciated primarily using the straight-line method over the estimated useful life of the asset. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful lives, which range from two to ten years, of the related assets. Salvage value rate is determined to 0% based on the economic value of the property, plant and equipment at the end of the estimated useful lives as a percentage of the original cost. Estimated useful lives Buildings 20 years Machinery and equipment 5 to 10 years Charging infrastructure 5 years Vehicles 4 to 5 years Computer and electronic equipment 3 years Others 2 to 5 years Depreciation for mold and tooling is computed using the units-of-production The cost of maintenance and repairs is expensed as incurred, whereas the cost of renewals and betterment that extends the useful lives of property, plant and equipment is capitalized as additions to the related assets. Construction in progress represents property, plant and equipment under construction and pending installation and is stated at cost less accumulated impairment losses, if any. Completed assets are transferred to their respective asset classes and depreciation begins when an asset is ready for its intended use. Interest expense on outstanding debt is capitalized during the period of significant capital asset construction. Capitalized interest expense on construction-in-progress The gain or loss on the disposal of property, plant and equipment is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statement of comprehensive loss. The loss on the disposal of property, plant and equipment amounting to RMB30,275, RMB1,191 and RMB6,167 were recognized in operating expenses during the years ended December 31, 2018, 2019 and 2020, respectively.
Intangible assets, net	(n) Intangible assets, net Intangible assets consist of manufacturing license, license plate, software and license of maintenance and overhauls. Intangible assets with finite lives, including software and license of maintenance and overhaul, are carried at acquisition cost less accumulated amortization and impairment, if any. Finite lived intangible assets are tested for impairment if impairment indicators arise. Amortization of intangible assets with finite lives are computed using the straight-line method over the estimated useful lives as below: Estimated useful lives Software 2 to 10 years License of maintenance and overhauls 26 months The estimated useful lives of intangible assets with finite lives are reassessed if circumstances occur that indicate the original estimated useful lives have changed. Intangible assets that have indefinite useful life were manufacturing license and license plate as of December 31, 2020. The Group evaluates indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support indefinite useful lives. The value of indefinite-lived intangible assets is not amortized, but tested for impairment annually or whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable.
Land use rights, net	(o) Land use rights, net Land use rights are recorded at cost less accumulated amortization. Amortization is provided on a straight-line basis over the estimated useful lives which are 50 years that represent the terms of land use rights certificate.
Impairment of long-lived assets	(p) Impairment of long-lived assets Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will affect the future use of the assets) indicate that the carrying amount may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment by comparing carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. Fair value is determined using anticipated cash flows discounted at a rate commensurate with the risk involved.
Warranties	(q) Warranties The Group provides a manufacturer’s standard warranty on all vehicles sold. The Group accrues a warranty reserve for the vehicles sold by the Group, which includes the Group’s best estimate of the projected costs to repair or replace items under warranties and recalls when identified. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Group’s relatively short history of sales, and changes to the Group’s historical or projected warranty experience may cause material changes to the warranty reserve in the future. The portion of the warranty reserve expected to be incurred within the next 12 months is included within accruals and other liabilities, while the remaining balance is included within other non-current The Group considers the standard warranty is not providing incremental service to customers rather an assurance to the quality of the vehicle, and therefore is not a separate performance obligation and should be accounted for in accordance with ASC 460, Guarantees. The Group also provides extended lifetime warranty embedded through a vehicle sales contract. The extended lifetime warranty is likely incremental service provided to the customer to differentiate with other peer companies, as such, the lifetime warranty is a separate performance obligation distinct from other promises and should be accounted for in accordance with ASC 606.
Revenue recognition	(r) Revenue recognition Revenue is recognized when or as the control of the goods or services is transferred upon delivery to customers. Depending on the terms of the contract and the laws that apply to the contract, control of the goods and services may be transferred over time or at a point in time. Control of the goods and services is transferred over time if the Group’s performance: • provides all of the benefits received and consumed simultaneously by the customer; • creates and enhances an asset that the customer controls as the Group performs; or • does not create an asset with an alternative use to the Group and the Group has an enforceable right to payment for performance completed to date. If control of the goods and services transfers over time, revenue is recognized over the period of the contract by reference to the progress towards complete satisfaction of that performance obligation. Otherwise, revenue is recognized at a point in time when the customer obtains control of the goods and services. Contracts with customers may include multiple performance obligations. For such arrangements, the Group allocates overall contract price to each distinct performance obligation based on its relative standalone selling price in accordance with ASC 606. The Group generally determines standalone-selling prices for each individual distinct performance obligation identified based on the prices charged to customers. If the standalone selling price is not directly observable, it is estimated using expected cost plus a margin or adjusted market assessment approach, depending on the availability of observable information, the data utilized, and considering the Group’s pricing policies and practices in making pricing decisions. Assumptions and estimations have been made in estimating the relative selling price of each distinct performance obligation, and changes in judgments on these assumptions and estimates may affect the revenue recognition. The discount provided in the contract are allocated by the Group to all performance obligations as conditions under ASC 606-10-32-37 When either party to a contract has performed, the Group presents the contract in the consolidated balance sheet as a contract asset or a contract liability, depending on the relationship between the entity’s performance and the customer’s payment. A contract asset is the Group’s right to consideration in exchange for goods and services that the Group has transferred to a customer. A receivable is recorded when the Group has an unconditional right to consideration. A right to consideration is unconditional if only the passage of time is required before payment of that consideration is due. If a customer pays consideration or the Group has a right to an amount of consideration that is unconditional, before the Group transfers a good or service to the customer, the Group presents the contract liability when the payment is made or a receivable is recorded (whichever is earlier). A contract liability is the Group’s obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. The Group’s contract liabilities are primarily resulted from the multiple performance obligations identified in the vehicle sales contract, which is recorded as deferred revenue and recognized as revenue based on the consumption of the services or the delivery of the goods. Vehicle sales The Group generates revenue from sales of electric vehicles, together with a number of embedded products and services through a contract. The Group identifies the customers who purchase the vehicle as its customers. There are multiple distinct performance obligations explicitly stated in a series of contracts including sales of vehicle, free charging within 4 years or 100,000 kilometers, extended lifetime warranty, option between household charging pile and charging card, vehicle internet connection services, and services of lifetime free charging in XPeng-branded super charging stations and lifetime warranty of battery which are accounted for in accordance with ASC 606. The standard warranty provided by the Group is accounted for in accordance with ASC 460, Guarantees, and the estimated costs are recorded as a liability when the Group transfers the control of vehicle to a customer. Car buyers in the PRC are entitled to government subsidies when they purchase electric vehicles. For efficiency purpose and better customer service, the Group or Zhengzhou Haima Automobile Co., Ltd. (“Haima Auto”) applies for and collect such government subsidies on behalf of the customers. Accordingly, customers only pay the amount after deducting government subsidies. The Group determined that the government subsidies should be considered as part of the transaction price because the subsidy is granted to the buyer of the electric vehicle and the buyer remains liable for such amount in the event the subsidies were not received by the Group due to the buyer’s fault such as refusal or delay of providing application information. The overall contract price is allocated to each distinct performance obligation based on the relative estimated standalone selling price. The revenue for sales of the vehicle and household charging pile is recognized at a point in time when the control of the vehicle is transferred to the customer and the charging pile is installed at customer’s designated location. For vehicle internet connection service, the Group recognizes the revenue using a straight-line method. For the extended lifetime warranty and lifetime warranty of battery, given limited operating history and lack of historical data, the Group decides to recognize the revenue over time based on a straight-line method initially, and will continue monitoring the cost pattern periodically and adjust the revenue recognition pattern to reflect the actual cost pattern as it becomes available. For the free charging within 4 years or 100,000 kilometers and charging card to be consumed to exchange for charging services, the Group considers that a measure of progress based on usage (rather than a time-based method) best reflects the performance as it’s typically a promise to deliver the underlying service rather than a promise to stand ready. For the services of lifetime free charging in XPeng-branded super charging station, the Group recognize the revenue over time based on straight-line method during the expected useful life of the vehicle. Initial refundable deposits for intention orders and non-refundable XPILOT, the Group’s autonomous driving system, provides assisted driving and parking functions tailored for driving behavior and road conditions in China. The Group plans to roll out XPILOT 3.0 in January 2021. A customer can subscribe for XPILOT 3.0 by either making a lump sum payment or paying annual installments for a three-year period. XPILOT 3.0 will feature several new functions, including a navigation guided pilot for highway driving and advanced automated parking. Revenue related to XPILOT 3.0 is recognized at a point in time when autonomous driving functionality of XPILOT 3.0 is activated and transferred to the customers. Other services The Group provides variable other services to customers including services embedded in a sales contract, supercharging service, maintenance service, ride hailing services and vehicle leasing service. Services embedded in a sales contract may include free charging within 4 years or 100,000 kilometers, extended lifetime warranty, option between household charging pile and charging card, vehicle internet connection services, lifetime warranty of battery and services of free charging services in XPeng-branded charging station. Other services also include supercharging service and maintenance service. These services are recognized under ASC 606. The Group provides ride hailing services with smart commuting solutions to customers by using the Group’s self-owned G3 vehicles and hiring and training drivers managed by third party agents via service agreement. The Group believes it acts as a principle in the ride hailing services as it controls a specified good or service before it is transferred to the customers. The revenue for ride hailing services is recognized overtime in a period when the ride hailing services is consumed under ASC 606. Revenue from vehicle leasing service to customers under operating lease and finance lease are recognized under ASC 842. Practical expedients and exemptions The Group follows the guidance on immaterial promises when identifying performance obligations in the vehicle sales contracts and concludes that lifetime roadside assistance, traffic ticket inquiry service, courtesy car service, on-site Considering the qualitative assessment and the result of the quantitative estimate, the Group concluded not to assess whether promises are performance obligation if they are immaterial in the context of the contract and the relative stand-alone fair value individually and in aggregate is less than 1% of the contract price, namely the lifetime roadside assistance, traffic ticket inquiry service, courtesy car service, on-site Customer Upgrade Program In the third quarter of 2019, due to the upgrade of the latest vehicle model, G3 2020, the Group voluntarily offered all owners of G3 2019 model the options to either receive loyalty points, valid for 5 years since the grant date, which can be redeemed for goods or services, or obtain an enhanced trade-in As both options provide a material right (a significant discount on future goods or services) for no consideration to existing customers with unfulfilled performance obligations, the Group considers this arrangement to be a modification of the existing contracts with customers. Further, as the customers did not pay for the additional rights, the contract modification is accounted for as the termination of the original contract and commencement of a new contract, which will be accounted for prospectively. The material right from the loyalty points or the trade-in For the material right from loyalty points, the Group estimated the probability of points redemption when determining the stand-alone selling price. Since the fact that most merchandise can be redeemed without requiring a significant amount of points compared with the amount of points provided to customers, the Group believes it is reasonable to assume all points will be redeemed and no forfeiture is estimated currently. The amount allocated to the points as a separate performance obligation is recorded as a contract liability (deferred revenue) and revenue will be recognized when future goods or services are transferred. The Group will continue to monitor forfeiture rate data and will apply and update the estimated forfeiture rate at each reporting period. According to the terms of the trade-in trade-in trade-in trade-in 120-day trade-in trade-in trade-in trade-in trade-in trade-in trade-in trade-in
Cost of sales	(s) Cost of sales Vehicle Cost of vehicle revenue includes direct parts, material, labor cost and manufacturing overhead (including depreciation of assets associated with the production) and reserves for estimated warranty expenses. Cost of vehicle revenue also includes charges to write-down the carrying value of the inventories when it exceeds its estimated net realizable value and to provide for on-hand Services and others Cost of services and others revenue generally includes cost of direct part, material, labor costs, installment costs, costs associated with providing non-warranty Cost of ride hailing services revenue also includes agent and service fee paid to third party agents and revenue sharing fee to a third party data supporting entity.
Research and development expenses	(t) Research and development expenses All costs associated with research and development (“R&D”) are expensed as incurred. R&D expenses consist primarily of employee compensation for those employees engaged in R&D activities, design and development expenses with new technology, materials and supplies and other R&D related expenses. For the years ended December 31, 2018, 2019 and 2020, R&D expenses were RMB1,051,219, RMB2,070,158 and RMB1,725,906 respectively.
Selling, general and administrative expenses	(u) Selling, general and administrative expenses Sales and marketing expenses consist primarily of employee compensation and marketing, promotional and advertising expenses. Advertising expenses consist primarily of costs for the promotion of corporate image and product marketing. Selling costs are expenses as incurred. For the years ended December 31, 2018, 2019 and 2020, advertising costs were RMB58,326 and RMB168,170 and RMB517,135 respectively, and total sales and marketing expenses were RMB317,109, RMB668,602 and RMB1,737,765 respectively. General and administrative expenses consist primarily of employee compensation for employees involved in general corporate functions and those not specifically dedicated to R&D activities, depreciation and amortization expenses, legal, and other professional services fees, lease and other general corporate related expenses. For the years ended December 31, 2018, 2019 and 2020, general and administrative expenses were RMB325,432, RMB495,967 and RMB1,182,884 respectively.
Employee benefits	(v) Employee benefits Full-time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, work-related injury benefits, maternity insurance, medical care, employee housing fund and other welfare benefits are provided to the employees. Chinese labor regulations require that the PRC subsidiaries and VIEs of the Group make contributions to the government for these benefits based on certain percentages of the employees’ salaries, up to a maximum amount specified by the local government. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed and no legal obligation beyond the contributions made. Total amounts of such employee benefit expenses, which were expensed as incurred, were approximately RMB104,201, RMB215,046 and RMB152,361 for the years ended December 31, 2018, 2019 and 2020, respectively.
Government grants	(w) Government grants The Group’s PRC based subsidiaries received government subsidies from certain local governments. The Group’s government subsidies consist of specific subsidies and other subsidies. Specific subsidies are subsidies that the local government has provided for a specific purpose, such as land fulfillment costs and production and capacity subsidies related to the manufacturing plant construction of Zhaoqing XPeng (“Zhaoqing manufacturing plant”). Other subsidies are the subsidies that the local government has not specified its purpose for and are not tied to future trends or performance of the Group, receipt of such subsidy income is not contingent upon any further actions or performance of the Group and the amounts do not have to be refunded under any circumstances. The Group recorded specific subsidies as other non-current
Income taxes	(x) Income taxes Current income taxes are recorded in accordance with the regulations of the relevant tax jurisdiction. The Group accounts for income taxes under the asset and liability method in accordance with ASC 740, Income Tax. Under this method, deferred tax assets and liabilities are recognized for the tax consequences attributable to differences between carrying amounts of existing assets and liabilities in the consolidated financial statements and their respective tax basis, and operating loss carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive loss in the period of change. Valuation allowances are established when necessary to reduce the amount of deferred tax assets if it is considered more likely than not that amount of the deferred tax assets will not be realized. Uncertain tax positions The guidance on accounting for uncertainties in income taxes prescribes a more likely than not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Guidance was also provided on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. The Group recognizes interests and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheet and under other expenses in its consolidated statements of comprehensive loss. The Group did not recognize any significant interest and penalties associated with uncertain tax positions for the years ended December 31, 2018, 2019 and 2020. As of December 31, 2019 and 2020, the Group did not have any significant unrecognized uncertain tax positions. Adoption of ASU 2016-16 In October 2016, the FASB issued ASU 2016-16, 2016-16 non-current
Share-based compensation	(y) Share-based compensation The Group grants restricted share units (“RSUs”), restricted shares and share options (collectively, “Share-based Awards”) to eligible employees and accounts for share-based compensation in accordance with ASC 718, Compensation—Stock Compensation. Share-based awards are measured at the grant date fair value of the awards and recognized as expenses using graded vesting method or straight-line method, net of estimated forfeitures, if any, over the requisite service period. For awards with performance conditions, Company would recognize compensation cost if and when it concludes that it is probable that the performance condition will be achieved. The fair value of the RSUs and restricted shares granted prior to the completion of the IPO were assessed using the income approach/discounted cash flow method, with a discount for lack of marketability given that the shares underlying the awards were not publicly traded at the time of grant. This assessment requires complex and subjective judgments regarding the Company’s projected financial and operating results, its unique business risks, the liquidity of its ordinary shares and its operating history and prospects at the time the grants were made. The fair value of share options granted prior to the completion of the IPO is estimated on the grant or offering date using the Binomial option-pricing model. The assumptions used in share-based compensation expense recognition represent management’s best estimates, but these estimates involve inherent uncertainties and application of management judgment. If factors change or different assumptions are used, the share-based compensation expenses could be materially different for any period. Moreover, the estimates of fair value of the awards are not intended to predict actual future events or the value that ultimately will be realized by grantees who receive Share-based Awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company for accounting purposes. The fair value of the RSUs granted subsequent to the completion of the IPO is estimated based on the fair market value of the underlying ordinary shares of the Company on the date of grant. Share options granted to employees: Since 2015, Chengxing has granted options to certain directors, executive officers and employees. The options granted are exercisable only upon the completion of an IPO or change in control. Share options granted to employees includes both service condition and performance condition. Employees are required to provide continued service through the satisfaction of the occurrence of change of control or an IPO to retain the award since no share option would be vested prior to the occurrence of the Liquidity Event even though the service condition has been satisfied. Given the vesting of the share options granted is contingent upon the occurrence of the Liquidity Event, there is no share-based compensation expense to be recognized until the date of consummation of Liquidity Event. On June 28, 2020, the board of directors of the Company approved the 2019 Equity Incentive Plan (“ESOP Plan”) with 161,462,100 Class A ordinary shares reserved. Options, restricted shares, RSUs, dividend equivalents, share appreciation rights and share payments may be granted under the ESOP Plan. In June 2020, the Group agreed with the participants to cancel the existing stock options granted during the period between 2015 and the first quarter of 2020 along with a concurrent grant of a replacement RSUs (“Replacement”). Restricted share units granted to employees: Prior to the completion of the IPO, RSUs granted to employees include both service condition and performance condition. Employees are required to provide continued service through the satisfaction of the occurrence of Liquidity Event to retain the award since no RSU would be vested prior to the occurrence of the Liquidity Event even though the service condition has been satisfied. The Group also granted RSUs in 2020 with only performance condition and the RSUs would be vested upon the occurrence of Liquidity Event. Given the vesting of these two types of RSUs granted is contingent upon the occurrence of the Liquidity Event, there is no share-based compensation expense to be recognized until the date of consummation of Liquidity Event. In July 2020, RSUs vested immediately upon grant date were granted to employees and the share-based compensation expense were recognized immediately on the grant date. Subsequent to the completion of the IPO, the Group granted RSUs with only service condition to employees and the share-based compensation expense were recognized over the vesting period using straight-line method. Restricted shares granted to two co-founders: In the years ended December 31, 2018, 2019, two co-founders A change in any of the terms or conditions of restricted shares granted to two co-founders As of December 31, 2019, all the restricted shares of two co-founders
Statutory reserve	(z) Statutory reserve The Group’s subsidiaries and VIEs established in the PRC are required to make appropriations to certain non-distributable In accordance with the laws applicable to PRC’s Foreign Investment Enterprises, the Group’s subsidiaries registered as wholly owned foreign enterprises have to make appropriations from its after-tax after-tax In addition, in accordance with the Company Laws of the PRC, the VIEs of the Company registered as PRC domestic companies must make appropriations from its after-tax non-distributable after-tax The use of the general reserve fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increasing capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to staff and for the collective welfare of employees. No reserves are allowed to be transferred to the Company in terms of cash dividends, loans or advances, nor can they be distributed except under liquidation. During the years ended December 31,2018, 2019 and 2020, there is no statutory reserves.
Comprehensive loss	(aa) Comprehensive loss The Group applies ASC 220, Comprehensive Income, with respect to reporting and presentation of comprehensive loss and its components in a full set of financial statements. Comprehensive loss is defined to include all changes in equity of the Group during a period arising from transactions and other events and circumstances except those resulting from investments by shareholders and distributions to shareholders. For the years presented, the Group’s comprehensive loss includes net loss and other comprehensive loss, which primarily consists of the foreign currency translation adjustment that has been excluded from the determination of net loss.
Leases	(ab) Leases In February 2016, the FASB issued ASC 842, Leases, to require lessees to recognize all leases, with certain exceptions, on the balance sheet, while recognition on the statement of operations will remain similar to lease accounting under ASC 840. Subsequently, the FASB issued ASU No. 2018-10, No. 2018-11, No. 2018-20, 2019-01, No. 2016-02. (a) As a lessee (i) Operating lease The Group early adopted the ASUs as of January 1, 2018 using the cumulative effect adjustment approach. Upon adoption, the Group elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Group to carry forward the historical determination of contracts as leases, lease classification and not reassess initial direct costs for historical lease arrangements. In addition, the Group also elected the practical expedient to apply consistently to all of the Group’s leases to use hindsight in determining the lease term (that is, when considering lessee options to extend or terminate the lease and to purchase the underlying asset) and in assessing impairment of the Group’s right-of-use The Group includes a right-of-use right-of-use The Group has lease agreements with lease and non-lease non-lease The Group has elected not to present short-term leases on the consolidated balance sheet as these leases have a lease term of 12 months or less at commencement date of the lease and do not include options to purchase or renew that the Group is reasonably certain to exercise. The Group recognizes lease expenses for such short-term lease generally on a straight-line basis over the lease term. All other lease assets and lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Group’s leases do not provide an implicit rate of return, the Group uses the Group’s incremental borrowing rate based on the information available at adoption date or lease commencement date in determining the present value of lease payments. (b) As a lessor The Group provides vehicle leasing service to customers under operating lease and finance lease. (i) Operating lease The Group recognizes the lease payments as vehicle leasing income in profit or loss over the lease term on a straight-line basis. (ii) Finance lease At the commencement of the lease term, the aggregate of the minimum lease receivable at the inception of the lease and the initial direct costs is recognized as finance lease receivables, and the unguaranteed residual value is recorded at the same time. The difference between the aggregate of the minimum lease receivable, the initial direct costs and the unguaranteed residual value, and the aggregate of their present values is recognized as unearned finance income. The net amount of finance lease receivables less unearned finance income is divided into finance lease receivable – net and current portion of finance lease receivable – net due within one year for presentation. Finance lease receivables are carried at amortized cost net of loss allowance for finance lease receivables. When determining the loss allowance for a net investment in the lease, the Group takes into consideration the collateral relating to the net investment in the lease. The collateral relating to the net investment in the lease represents the cash flows that the Group would expect to receive (or derive) from the lease receivable and the unguaranteed residual asset during and following the end of the remaining lease term. Lease income from finance lease is recognized in other revenues using the effective interest method.
Dividends	(ac) Dividends Dividends are recognized when declared. No dividends was declared for the years ended December 31, 2018 , 2019 and 2020, respectively.
Earnings (losses) per share	(ad) Earnings (losses) per share Basic earnings (loss) per share is computed by dividing net income (loss) attributable to holders of ordinary shares, considering the accretion on Preferred Shares to redemption value, deemed dividend due to extinguishment of Preferred Shares, deemed dividend due to modification of Preferred Shares, deemed dividend due to reclassification from mezzanine equity to ordinary shares upon extinguishment of Redeemable Shares and deemed contribution from repurchase of Preferred Shares, by the weighted average number of.ordinary shares outstanding during the period using the two-class two-class if-converted
Segment reporting	(ae) Segment reporting ASC 280, Segment Reporting, establishes standards for companies to report in their financial statements information about operating segments, products, services, geographic areas, and major customers. Based on the criteria established by ASC 280, the Group’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer, who reviews consolidated results when making decisions about allocating resources and assessing performance of the Group. As a whole and hence, the Group has only one reportable segment. The Group does not distinguish between markets or segments for internal reporting. As the Group’s long-lived assets are substantially located in the PRC, no geographical segments are presented.
