WASHINGTON — The U.S. Energy Department on Tuesday will unveil final rules that will significantly soften its proposal that would have slashed electric vehicles' mileage ratings to meet government fuel economy requirements in 2027, sources said.
Automakers cited administration estimates that under the 2023 proposals, General Motors would face $6.5 billion in fines, followed by Chrysler parent Stellantis with $3 billion, and Ford with $1 billion through that year. The National Highway Traffic Safety Administration is set to proposal final revised CAFE rules this spring.
The Miles Per Gallon equivalent ratings have not been updated in more than two decades and are determined using values for national electricity, petroleum generation and distribution efficiency and driving patterns. Automakers are expected to be able to produce significantly fewer EVs in 2030 under the final rules. The Alliance for Automotive Innovation representing nearly all major automakers except Tesla had urged EPA to finalize rules resulting in closer to a 50% EV sales target by 2030.
