What Is the Worst Gas Mileage SUV
The worst gas mileage SUVs are typically large, heavy, or off-road-oriented models with powerful engines. These vehicles often have EPA ratings below 15 mpg combined, especially older or full-size body-on-frame designs. Real-world mileage can be even lower when towing or driving in cities.
Examples of Low MPG SUVs
Models such as the Ford Expedition, Chevrolet Suburban, and Toyota Sequoia frequently rank among the lowest mpg SUVs. Some older luxury or performance SUVs also consume more fuel due to weight and engine size. The U.S. Department of Energy lists many of these models in its vehicle comparison tools.
Why These SUVs Use More Fuel
Large displacement engines, all-wheel drive systems, and heavy frames increase fuel use. Aerodynamic drag, frequent short trips, and aggressive driving further reduce efficiency. Drivers who need towing capacity or off-road features often accept lower mpg as part of the vehicle's design.
