President Donald Trump is expected to roll back fuel efficiency standards for cars and trucks set by the Biden administration during an announcement at the White House on Dec. 3, making it easier for automakers to sell gas-powered vehicles.

Signed into law in 1975, the Corporate Average Fuel Economy (CAFE) standards regulate how far vehicles must travel on a gallon of fuel. The National Highway Traffic Safety Administration is expected to propose reducing the fuel economy requirements from model years 2022 to 2031, a move that will save Americans $109 billion, a White House official told USA TODAY.

"Joe Biden's fuel efficiency regulations would have raised the cost of a new vehicle by $1,000," the White House said in a post on X. "PRESIDENT TRUMP IS HITTING RESET- saving Americans $109 BILLION!"

The Biden standards would have compelled widespread shifts to electric vehicles that American consumers did not ask for, accompanied by significant cost-of-living increases, the official said.

Executives from the three largest automakers, Ford, General Motors, and Stellantis (parent company of Chrysler) were expected at the White House for the announcement.
