How this ranking works

Values come from FuelEconomy.gov, EPA certification data and NHTSA records shown on each vehicle's page. Only the best-placed version of each model family is listed, so one model cannot fill the list. Electric vehicles are excluded from fuel-consumption rankings and ranked by range instead.
