The U.S. Environmental Protection Agency said Wednesday that the average fuel economy of 2015 model-year vehicles increased 0.5 mile per gallon to a record high of 24.8 miles per gallon. Mazda had the highest average fuel economy of 29.6 mpg, the EPA said. Fiat Chrysler had the lowest, at 20.8 mpg.

Weight loss is one reason that fuel economy is increasing.
