vehicle fuel economy. Specifically, this study examines actual fuel economy of cars and light trucks (pickup trucks, SUVs, and vans) from 1966 through 2017. Calculated vehicle fuel economy is available going back to 1923. The primary measure in this analysis is the average miles driven per gallon of fuel for each year. For 1966 through 1985, fuel economy was calculated from the information in a summary publication by the U.S.
