The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. Fuel economy average for the US fleet, per the Trends report, is 24.1 Click to enlarge.
