Trump approves new fuel economy standards, ending Biden-era EV push
Donald Trump says he has approved new US fuel economy standards that end Biden-era requirements, promising lower car prices and more than $100bn of auto investment in the United States.
US President Donald Trump has said he approved new federal fuel economy standards for cars and trucks that roll back Biden-era requirements, declaring on Truth Social on Saturday that they “TERMINATE” what he called the previous administration’s electric vehicle mandate.
“These new Standards will take the waste out of building cars in America. That means LOWER PRICES, saving families thousands on a new, beautiful, and safe car,” Trump wrote in the post. He said more than $100 billion was being invested in American automobile manufacturing and thanked Transportation Secretary Sean Duffy and Commerce Secretary Howard Lutnick.
The administration proposed a sweeping reset of Corporate Average Fuel Economy standards in December that would substantially cut fuel-efficiency requirements for passenger cars and light trucks through model year 2031. Under that proposal, the National Highway Traffic Safety Administration estimated the US vehicle fleet would average about 34.5 miles per gallon by 2031, compared with roughly 50.4 mpg projected under Biden-era standards.
The Biden administration did not require Americans to buy electric vehicles, but its fuel economy and tailpipe-emissions rules were built on the assumption that EVs would make up a growing share of new-car sales — a 2021 executive order aimed for half of all new vehicle sales to be electric by 2030. NHTSA projected its own proposal would save about $930 per vehicle, though a Reuters report said it would add 100 billion gallons of fuel consumption through 2050 and increase carbon dioxide emissions by 5 per cent.
Duffy said in late August that the administration would unveil a “common-sense fuel economy standard because we want Detroit to build cars that Americans want to buy — not cars that Democrats want Washington to build.” The final parameters of the standards Trump approved have not yet been publicly disclosed.
