Best Gas Mileage SUVs: Most Fuel-Efficient SUVs for 2021 | Edmunds

Best Gas Mileage SUVs for 2021

SUVs have been gaining in popularity for decades, supplanting traditional sedans, wagons and hatchbacks as the go-to choice for both family and personal transport. Like every other type of vehicle, SUVs have benefited from advances in engineering and technology that have increased fuel efficiency by leaps and bounds.

But which SUVs have the best mpg? We crunched the numbers and came up with the most efficient SUVs for 2021 in a wide variety of classes and sizes. Keep in mind that these models aren’t necessarily top-rated in their segments — this list is purely focused on mpg numbers. It’s also worth noting that diesel SUVs have fallen off the map, with the diesel mpg champs of yesteryear giving way to a new crop of hybrids. Moreover, while some brands that didn’t make this list may have a number of fuel-efficient SUVs — Chevrolet, Hyundai and Nissan come to mind — we’re looking for the best SUV fuel economy in each class, and brands such as Ford and Toyota just do it a little better at the moment.

Our list of fuel-efficient SUVs is split up into four distinct categories: small, midsize, large and luxury. Our figures are based on the EPA’s official estimates for traditional internal combustion engines and hybrids. Since electric vehicles don’t use fuel, we’ve taken them out of the running.
