Detroit Automakers Face Billions in Fines Under Proposed Fuel Economy Rules, Claiming Higher Costs Than Foreign Brands

Proposed fuel economy rules through 2032 would cost GM $6.5 billion in fines and Stellantis $3 billion.

Ford faces about $1 billion in penalties.

Letter says new rules would result in "disproportionately higher compliance costs" for U.S. automakers.

Detroit automakers face $2,151 per vehicle in compliance costs compared to $546 for other automakers.

Policy "would reward those auto manufacturers resisting the transition to a fully electric future the most."
