The HFE is an attempt at making the 1500 as efficient as possible by removing certain engine parts and including low-resistance tires as standard. This model is only available in 4x2 guise, but is available with either the base gasoline V6 or the torquey EcoDiesel V6. The economy gains aren’t that big, and at some point, you will load something on the bed, at which stage it will consume a lot of fuel. Pickup trucks are inherently inefficient, and the HFE’s modifications aren’t enough to change that. It makes more sense with the diesel engine, which is already frugal to start with. This option will soon be available on this specific model.
Engine: 3.6L V6 24V VVT eTorque UPG I, Transmission: 8-Speed Automatic (850RE)
