30 Trucks With the Best Fuel Mileage

3. Ram 1500 (20/27)

The RAM 1500 HFE leads the way of fuel efficient trucks. With a 3.6-liter Pentastar V6 that cranks out 305 horsepower and 269 lb-ft of torque, the RAM 1500 HFE can do some serious work. At the same time, it nets 25 miles per gallon on the highway, and its standard 8-speed automatic delivers luxury-smooth shifts. If you don’t want the HFE package, by the way, consider that the regular RAM 1500 V6 still achieves 20 mpg city/27 mpg highway.
