Ram has announced the launch of the 1500 EcoDiesel HFE pickup truck, which increases highway mileage to 29 mpg (8.1 l/100 km) compared to the standard 1500 EcoDiesel’s 28 mpg (8.4 l/100 km).

EcoDiesel HFE (high fuel efficiency) will be the first diesel powertrain offered in the Ram 1500 Express model and will deliver the highest fuel economy among all full-size truck competitors – Ram says it’s 12 percent more fuel-efficient than the next-closest competitor.

The Ram 1500 EcoDiesel HFE gets an EPA-certified 29 mpg highway fuel economy rating, while its city and combined mpgs are 21 (11.2 l/100 km) and 24 (9.8 l/100km), respectively. These ratings are also claimed to be the highest among all pickups.

The Ram 1500 EcoDiesel HFE features a unique trim package based on the popular Ram 1500 Tradesman Quad Cab four-door body, with a 6-ft 4-in (1,930mm) bed and 20-inch wheels.

The model is also available with a body-colored fascia adopted from the Ram Express model, which gives the Ram EcoDiesel HFE a distinctive exterior appearance compared to other EcoDiesel-powered Ram 1500s. Other features include wheel-to-wheel side steps and a tri-fold tonneau cover which improve functionality and aerodynamics, thus contributing to better fuel efficiency.

Ram 1500 EcoDiesel HFE models will also get a new HFE badge that backs its mileage claims. The model will go on sale late first quarter of 2015.
