Best and Worst Gas Mileage 2018
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 by 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.
