Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”).
Unaudited Interim Financial Statements	Unaudited Interim Financial Statements The condensed consolidated balance sheet as of June 30, 2022, the condensed consolidated statements of operations and the condensed consolidated statements of changes in stockholders’ equity for the three-months and six-months ended June 30, 2022 and 2021, and the condensed consolidated statements of cash flows for the six-months ended June 30, 2022 and 2021, as well as other information disclosed in the accompanying notes, are unaudited. The consolidated balance sheet as of December 31, 2021 was derived from the audited consolidated financial statements as of that date. The interim condensed consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 28, 2022. Comprehensive loss is not separately presented as the amounts are equal to net loss for the three and six-months ended June 30, 2022 and 2021. The interim condensed consolidated financial statements and the accompanying notes have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The condensed consolidated financial statements for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future years or interim periods.
Supplier Risk	Supplier Risk The Company finalized nomination of suppliers during the quarter for engineering, development, testing, tooling and production of components for serial production of its vehicles. As of June 30, 2022, these supplier contracts do not represent unconditional purchase obligations with take-or-pay or specified minimum quantities provisions with the exception of an agreement securing battery capacity for the Fisker Ocean SUV. Under the terms of the agreement, the battery supplier will deliver two different battery solutions for the Fisker Ocean SUV, with an initial battery capacity of over 5 gigawatt-hours annually, from 2023 through 2025.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP required management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the condensed consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates.
Fair Value Measurements	Fair Value Measurements The Company follows the accounting guidance in ASC 820 Fair Value Measurement ("ASC 820"), for its fair value measurements of financial assets and liabilities measured at fair value on a recurring basis. Fair value is defined as 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 at the measurement date. 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 accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace. Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
Income Taxes	Income Taxes Income taxes are recorded in accordance with ASC 740, Income Taxes (“ASC 740”), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the condensed consolidated financial statements or tax returns. Deferred tax assets and liabilities are determined based on the difference between the consolidated financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are provided, if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. There are transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. As of June 30, 2022, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2021. The Company’s income tax provision consists of an estimate for U.S. federal, foreign and state income taxes based on enacted rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities, and changes in the tax law. The Company maintains a valuation allowance against the full value of its U.S. and state net deferred tax assets because the Company believes the recoverability of the tax assets is not more likely than not as of June 30, 2022.
Derivative Liability	Derivative Liability The Company accounts for its public and private warrants as a derivative liability initially measured at its fair values and remeasured in the condensed consolidated statements of operations at the end of each reporting period. When the warrants are exercised, the corresponding derivative liability is de-recognized at the underlying fair value of the Class A common stock that is issued to the warrant holder less any cash paid in accordance with the warrant agreement. Upon either cash or cashless exercise, the de-recognized derivative liability results in an increase in additional paid in capital equal to the difference between the fair value of the underlying Class A common stock and its par value. A cashless exercise results in the warrant holder surrendering Class A common stock equal to the stated warrant exercise price based on the contractual terms in the warrant agreement that govern the cashless conversion.
Equity Awards	Equity Awards The grant date for an option or stock award is established when the grantee has a mutual understanding of the key terms and conditions of the option or award, the award is authorized, including all the necessary approvals unless approval is essentially a formality or perfunctory, and the grantee begins to benefit from, or be adversely affected by, underlying changes in the price of the Company’s Class A common shares. An award or option is authorized on the date that all approval requirements are completed (e.g., action by the compensation committee approving the award and the number of options, restricted shares or other equity instruments to be issued to individual employees).
Net Loss per Share of Common Stock	Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class method under which earnings are allocated to both common shares and participating securities. Undistributed net losses are allocated entirely to common shareholders since the participating security has no contractual obligation to share in the losses. Basic net loss per share is calculated by dividing the net loss attributable to common shares by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share of common stock is computed by dividing the net loss using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of stock-based compensation awards and warrants to purchase common stock (using the treasury stock method).
Foreign Currency Remeasurement and Transactions	Foreign Currency Remeasurement and Transactions The functional currency of the Company’s U.K., German, Indian and Austrian subsidiaries is the U.S. Dollar. For this subsidiary, monetary assets and liabilities denominated in non U.S. currencies are re-measured to U.S. Dollars using current exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities denominated in non-U.S. currencies are maintained at historical U.S. Dollar exchange rates. Expenses are re-measured at average U.S. Dollar monthly rates. Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency. Transaction gains and losses are immaterial for all periods presented. In April and July 2022, the Company purchased 130.1 million Euros for 140.0 million U.S. dollars, a currency exchange rate of 1 U.S. dollar for 1.076 Euro and 50.0 million Euros for 50.9 million U.S. dollars, a currency exchange rate of 1 U.S. dollar for1.018 Euro, which are designed to provide an economic hedge against future foreign currency exposures.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In December 2020, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU No. 2019-12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. This guidance had no effect on the Company’s condensed consolidated financial statements upon adoption in 2022. In June 2021, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40). This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The ASU eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The ASU also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. The ASU amends the diluted earnings per share guidance, including the requirement to use if-converted method for all convertible instruments and an update for instruments that can be settled in either cash or shares. We early adopted ASU 2020-06 effective on January 1, 2021 applying the modified retrospective method. Since the Company does not have any financial instruments as of January 1, 2021 within the scope of ASU 2020-06, early adoption had no effect on the Company’s condensed consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. This ASU also provides updated guidance regarding the impairment of available-for-sale debt securities and includes additional disclosure requirements. The new guidance is effective for non-public companies, and public business entities that meet the definition of a Smaller Reporting Company as defined by the Securities and Exchange Commission (SEC), for interim and annual periods beginning after December 15, 2022. On December 31, 2021, the Company became a large accelerated filer, as defined by the SEC, and, as a result, adopted this guidance effective January 1, 2021, which did not have a material impact on the Company's consolidated financial statements.
