2015 Ram 1500 EcoDiesel HFE
2015 Ram 1500 EcoDiesel HFE""
Ram Trucks has managed to eek out another mile per gallon from the already fuel-efficient Ram 1500 EcoDiesel pickup, proving the Detroit Auto Show wasn’t all about brawny off-road trucks. Ram’s new class-leading numbers are EPA-certified at 21 mpg city, 24 mpg combined, and 29 mpg highway. The upgraded mileage comes thanks to the HFE, or High Fuel Efficiency package. But technically, the Ram HFE is no different than any other Ram EcoDiesel, including its engine, transmission, and gearing specifications. It all comes down to equipment packaging and aerodynamics.
Engineers figured out the low-optioned Tradesman trim level combined with the shorter Quad Cab and six-foot, four-inch bed offers the slipperiest shape of the truck line. Add to that the prior knowledge of the wheel-to-wheel running boards and a tonneau cover’s ability to cut drag, and you’ve got the most aerodynamic Ram yet.
This makes the HFE a full 12 percent more efficient than the next-closest competitor, the 2.7-liter EcoBoost-powered 2015 Ford F-150, rated at 26 mpg highway.
For current Ram EcoDiesel owners, adding the same tri-fold tonneau cover and extended side steps would likely result in improved fuel economy as well. Just don’t expect 29 mpg with a four-wheel-drive, Crew Cab truck.
Thankfully Ram didn’t neuter the Ram of its towing and hauling capabilities with tall gears, skinny tires, or a wimpy ECU tune. The truck is still able to haul 1,614 pounds in the bed and tow 8,050 pounds on the hitch.
