For more information on this story, 2015 RAM 1500 HFE Hauls 29 MPG Into Detroit and for all of our North American International Auto Show coverage please visit AutoGuide.com.What do you get when you take a Ram 1500 EcoDiesel and improve its aerodynamics? You get a truck that’s capable of 29 MPG on the highway and 24 MPG combined, good enough to be best in class.
The Ram 1500 HFE debuted today at the 2015 Detroit Auto Show, promising some pretty impressive fuel numbers. The trim package is only available on the Ram 1500 Tradesman Quad Cab four-door with a 6-ft 4-in bed and 20-inch wheels.
The fuel economy gains come thanks to wheel-to-wheel side steps and a tri-fold tonneau cover which contributes to better fuel efficiency through aerodynamics. That’s in addition to the usual fuel economy saving features like the eight-speed automatic transmission, 3.0-liter diesel engine, stop-start system, grille shutters and air suspension.
HFE models also get a unique badge that heralds their MPG claims. Full fuel economy ratings are 21 mpg city, 29 mpg highway and 24 mpg combined. Ram says that its truck is now 12 percent more fuel efficient than its closest competitor.
