Best Gas Mileage by Vehicle Class

Each year, the EPA compiles its Fuel Economy Guide to educate car buyers on fuel-efficient vehicles. While there are a growing number of cars and trucks that use alternative fuels, the majority of cars bought in this country are still fueled on gasoline alone, and this list highlights the best and worst in each segment. Figures do not include estimates for use of E85. Compare estimates for all vehicles at fueleconomy.gov.

Editor's note: If there are multiple drivetrains available for a vehicle, only the one with the highest mpg estimate is listed as a class leader to avoid redundancy. Visit the EPA website (fueleconomy.gov) to find the mileage estimates for specific drivetrains.

* The lowest and highest mpg ratings and average city/highway mpg is listed for each class; ranges include cars with manual and automatic transmissions. Ranges exclude hybrids, as well as cars that run on diesel fuel. The average and range only include ratings available at the time of publication.

** Average means the average combined mpg for the segment.
