The latest edition of the US Environmental Protection Agency (EPA) annual Automotive Trends Report finds that Model Year (MY) 2017 vehicle fuel economy was 24.9 miles per gallon, slightly higher than MY 2016, and a record high overall. Since MY 2004, fuel economy and CO 2 emissions have improved in eleven out of thirteen years.
