2015 Ram 1500 EcoDiesel HFE Gets 29 MPG Highway

Better aerodynamics bump up highway number by 1 mpg.

Ram is adding a new fuel-economy package for the turbodiesel version of its 1500 pickup that boosts highway fuel economy by 1 mpg in EPA testing. The new 2015 Ram 1500 EcoDiesel HFE (for "high fuel economy") gets a few aerodynamic revisions for a slight improvement to 29 mpg highway, while the city and combined numbers remain the same, at 20 mpg city and 23 mpg highway.

The HFE EcoDiesel is a trim level only available on Quad Cab, rear-wheel-drive versions of the truck. It comes standard with running boards and a tonneau cover for the bed, both of which contribute to the better aerodynamics, and in turn, better highway efficiency. The new EcoDiesel HFE joins the existing HFE variant for the Ram 1500's gasoline 3.6-liter V-6 model, which is rated at 18 mpg city, 25 mpg highway.

We don't yet have information on what the 2015 Ram 1500 EcoDiesel HFE will cost, but it will be a separate trim level within the lineup. Like other EcoDiesel models (pictured), the addition of the turbodiesel, 3.0-liter V-6 should add around $4,000 to the bottom line.

This new, slightly higher rating cements the 2015 Ram 1500's place at the top of the pickup truck efficiency race. The next-best 2015 Ford F-150 and its new, lighter aluminum body achieves up to 26 mpg highway with a twin-turbo, 2.7-liter V-6 and rear-wheel drive, and the 2015 Chevrolet Silverado gets up to 24 mpg highway.

The 2015 Ram 1500 EcoDiesel HFE will hit dealers this March, so stay tuned for more specific information about this new model within the next few weeks.
