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.
