Subsequent Event, Description																		On January 25, 2023, FFIE entered into a Limited Consent and Amendment No. 5 to the SPA (“Fifth Amendment”) with FF Simplicity as administrative and collateral agent and Senyun as purchaser, pursuant to which Senyun agreed to purchase 10.0 million in principal amount of additional SPA Notes no later than January 27, 2023, which 10.0 million amount was funded on January 26, 2023. Pursuant to the Fifth Amendment, FFIE also agreed (a) to use commercially reasonable efforts to file an amendment to the Company’s registration statement (File No. 333-268972) no later than January 29, 2023 and to seek effectiveness of such registration statement on or prior to February 10, 2023, which effectiveness notice was received on February 8, 2023; (b) to use commercially reasonable efforts to file an additional registration statement on Form S-1 registering the re-sale by Senyun of all remaining shares of Class A Common Stock underlying Senyun’s SPA Notes and SPA Warrants no later than February 10, 2023 and to seek effectiveness of such additional registration statement as promptly as practicable thereafter (which registration statement was eventually filed on February 13, 2023); (c) to honor the conversion notice submitted by Senyun on January 18, 2023, and to reserve sufficient shares of Class A Common Stock to satisfy the conversion and exercise of all of Senyun’s SPA Notes and SPA Warrants to the extent FFIE has sufficient authorized but unissued or uncommitted shares of Class A Common Stock. The notes subjected to the January 18, 2023 conversion notice were issued in February 2023.
Amount paid (in Dollars)								$ 135,000
Stockholder approval description								The Tranche C Notes constitute SPA Notes and, among others, are issuable at 10% original issue discount and have a $1.05 base conversion price subject to full ratchet anti-dilution price protection and other adjustments as set forth therein, five year interest make-whole (calculated using the greater of (x) $0.21 per share of Common Stock and (y) 90% of the lowest VWAP for the five consecutive trading days ending on the trading day that is immediately prior to the date on which interest is paid in shares of Common Stock), which entitle the lenders to receive all interest that accrued and would have accrued on their converted notes had they been held to maturity, 10% per annum interest rate (or 15% if paid in Common Stock subject to certain conditions). As part of the Sixth Amendment, the Company agreed to issue warrants, which constitute SPA Warrants, to purchase number of shares of Common Stock equal to 33% of such purchaser’s conversion shares, with an exercise price equal to $1.05 per share, subject to full ratchet anti-dilution price protection and other adjustments and a seven year termination date. Each purchaser also has the option to purchase a certain amount of additional notes and warrants from time to time for twelve months from the effective date of the Sixth Amendment (“Tranche D Notes”). The Company received gross proceeds of $70.0 million as part of the Sixth Amendment ($62.2 million net of original issue discount and transaction costs).
