President Trump is set to announce a rollback of federal fuel-economy requirements, reducing the standard from 50.4 miles per gallon under the Biden administration to an average of 34.5 miles per gallon for model year 2031. The decision will be formally announced on Monday by Transportation Secretary Sean Duffy and aims to lower new car prices, a key point in current high gas price conditions where California faces particularly steep gasoline costs due to its isolated fuel market and specific regulations. This rollback also limits states like California’s ability to set stricter auto emission standards and promotes the production of gas-powered vehicles over electric ones.

Story summary
On Saturday, President Donald Trump announced he would roll back fuel economy standards for cars and light trucks, reversing rules set by the Biden administration. In a social media post, Trump claimed the rollback would lower car prices, save families thousands of dollars on new vehicles, and boost American manufacturing jobs. The move would relax requirements to an average of 34.5 miles per gallon by 2031, down from the projected 50.4 mpg under Biden's regulations. Critics argue that the rollback could increase consumer costs at the pump and worsen air quality.
