Trump administration rolls back Biden-era fuel economy standards for automakers

The Trump administration finalized new fuel economy rules, lowering the required fleet average to 34.9 miles per gallon by model year 2031, down from a prior target of 50.4 mpg. Officials said the change could save Americans $138 billion over five years and reduce the average new vehicle price by $1,300 by 2031; some analysts have expressed doubt about that claim.
