As part of Ram’s Detroit announcements, the truck brand revealed a new, more fuel-efficient Ram 1500 model.

According to Ram, this new 2015 Ram 1500 EcoDiesel HFE further extend its claim on the industry’s highest fuel efficiency rating.

HFE stands for high fuel efficiency.

The 2015 Ram 1500 EcoDiesel HFE will deliver, according to Ram, the highest fuel economy among all full-size truck competitors — 12 percent higher than the next-closest competitor.


Ram said the EcoDiesel HFE gets an EPA-certified 29 mpg highway fuel economy rating. EcoDiesel HFE’s city and combined mpgs are 21 and 24, respectively, also highest among all pickups.

Regular EcoDiesel Ram trucks in 4×4 versions are rated at 19 mpg city, 27 mpg highway and 22 mpg combined; rear-wheel-drive models are rated at 20 mpg city, 28 mpg highway and 23 mpg combined.

Ram did not specify it, but the 2015 Ram 1500 EcoDiesel HFE is very likely a rear-wheel-drive model.

“Fuel efficiency is at the top of truck buyers’ priorities, and Ram is the recognized benchmark for the industry,” said Bob Hegbloom, President and CEO – Ram Truck Brand. “Twenty-nine miles per gallon cuts through the clutter. Ram invested in powertrain technologies and those are paying real dividends in the wallets of our customers.”

All Ram EcoDiesel models, including this new HFE version, are powered by a turbocharged 60-degree, dual overhead camshaft (DOHC) 24-valve 3.0-liter diesel V6 that produces 240 horsepower and 420 pound-feet of torque; this engine is combined to a TorqueFlite 8-speed automatic transmission.

This new fuel efficient HFE Ram features a unique trim package on the popular Ram 1500 Tradesman Quad Cab four-door body, with a 6-ft. 4-in. bed and 20-inch wheels.

Ram added the EcoDiesel HFE is also available with a body-colored fascia adopted from the Ram Express model, which is said to give the Ram EcoDiesel HFE a sporty exterior appearance not offered on other EcoDiesel-powered Ram 1500s.

To help with fuel efficiency, wheel-to-wheel side steps and a tri-fold tonneau cover have been added. These are the only modifications Ram has mentioned to explain the fuel consumption difference between the HFE and regular EcoDiesel models.


“The Ram 1500 EcoDiesel delivers dominant fuel efficiency across five configurations and nine trims,” said Mike Cairns, Director – Ram Truck Engineering. “The Quad Cab is a widely purchased configuration which delivers the best aero benefit of any half-ton truck.”

Ram stated the EcoDiesel HFE will go on sale late first quarter of 2015.
