Driving a 4x4 truck used to mean resigning yourself to big fuel bills, as the most fuel-efficient 4x4 trucks were gas hogs compared to most cars, and even compared to most 4x2 trucks. Truck makers wised up, and started to pay attention. They now build lighter trucks with much more efficient engines. In fact, each truck on our top 10 list averages 20 mpg combined or better, impressive figures for such capable vehicles. We consulted the Environmental Protection Agency’s official site, FuelEconomy.gov, for our ratings, and we’ve included variants within a model based on engine, transmission and fuel efficiency.
Here’s our list of the 10 Most Fuel-Efficient 4x4 Trucks, in descending order of combined city/highway mpg.
