WASHINGTON—The Biden administration on Monday raised fuel-efficiency standards for passenger cars and light-duty trucks, saying the new standards will reduce pollution and save consumers billions of dollars at the gas pump.
Auto makers must meet a fleetwide average of 55 miles a gallon for cars and light trucks by model year 2026, up from the 43 mpg standard set by the Trump administration for that year. The fleetwide mileage standard for the current 2021 model year is 40 mpg.
