Trump administration lowers fuel economy standards

The Trump administration released new fuel economy standards Monday that loosen requirements for automakers to control pollution from gasoline cars and light trucks. The rules follow Trump’s rejection of an Iranian proposal involving the Strait of Hormuz, a decision that boosted oil prices. Fuel economy standards are measured by how far new vehicles travel on a gallon of gasoline. The Department of Transportation and the National Highway Traffic Safety Administration estimate the final standards translate to about 34.9 miles per gallon (combined fleet average) for passenger cars and light trucks in the 2031 model year, down from the Biden-era projected 50.4 mpg. Transportation Secretary Sean Duffy said the change ends an “illegal mandate” tied to more costly EV production. The article also notes policy rollbacks since Trump took office, including ending EV purchase credits up to $7,500 and repealing certain mileage-related fines.
