10,000-lb. Towing Test: F-150 EcoBoost vs. Steep Colorado Highway

Offering the high horsepower of a gasoline engine paired with near-diesel levels of low-end torque, the 3.5L EcoBoost V6 in the Ford F-150 is the best of both worlds. The engine is also quite thrifty with fuel, but if you really push it, it can get thirsty … 2.9-mpg thirsty.

Some thirst is to be expected when you’re towing 10,000 pounds up steep Colorado highway, and while that’s a lot of pain to throw at any truck, the EcoBoost F-150 handles one of the steepest highway ascents in the United States like a champ. The twin-turbocharged EcoBoost motor transforms the Ford F-150 into the Steve-O of the truck world.
