The Biden administration and automakers are in the final stages of negotiating over ambitious new rules to accelerate the electric-vehicle transition that could cost Detroit's automakers billions and fuel an election-year clash over climate policy.

 

The White House could enact proposed Environmental Protection Agency regulations as soon as March that would mandate dramatic reductions in tailpipe emissions. The administration proposal would require boosting U.S. EV market share to 67% by 2032 from less than 8% in 2023.

 

General Motors (GM.N), Ford (F.N), and Stellantis (STLAM.MI), the European parent of U.S-based Ram and Jeep, have warned they cannot profitably transition their truck-heavy U.S. fleets that quickly, according to a Reuters analysis of automakers’ sales data and a review of comments to regulators.
