Trump finalizes rollback of US fuel economy standards to 34.9 mpg by 2031
The Trump administration has finalized a significant rollback of federal fuel economy standards, reducing the required average for passenger cars and light trucks to 34.9 miles per gallon by the 2031 model year, down from the Biden-era target of roughly 50 mpg. The Department of Transportation's "Freedom Means Affordable Cars" initiative aims to lower vehicle prices by reducing regulatory costs, but critics warn it will increase fuel consumption and emissions.
