From model year (MY) 2000 to MY 2019, the number of conventional gasoline vehicle models achieving an Environmental Protection Agency (EPA) combined rating of 45 mpg or greater increased from one model to eight models. Perhaps more notable is that these high-mpg vehicles have expanded from one small two-seater to several larger-size classes. Since MY 2014, most models offered with 45 mpg or greater have been midsize or large cars. To see fuel-efficient vehicles for the newest model year, go to the FuelEconomy website.
Note: Each model counted may be offered with multiple transmissions, engines, drive types, and trim levels that achieve 45 mpg or greater. For this figure, each model name was only counted once regardless of the number of variants available that meet or exceed 45 mpg.
