All major carmakers in the United States have united against proposed rules for higher fuel efficiency that would threaten them with fines totaling some $14 billion in the five years from 2027 to 2032.
In July, the National Highway Traffic Safety Administration proposed hiking fuel efficiency limits by an annual 2% for passenger cars and by 4% for trucks between 2027 and 2032.
That, the NHTSA said, would lead to an average fuel efficiency boost to 58 miles per gallon.
“If finalized as proposed, the updated standards would save Americans hundreds of dollars at the pump,” the NHTSA said at the time in a press release, “all while making America more energy secure and less reliant on foreign oil.”
