2016 Ram 1500 HFE, Denver, CO, April 2016

It could not look adore it, however the Ram full-size pickup you see right here might be among the a lot more interesting brand-new trucks on the road today.

You may view it as this decade’s version of the Camaros, Mustangs, and Mopars that emerged in earlier days from back-corner “skunkworks” engineering teams at each Detroit automaker. Exactly how so, you ask?

This Ram isn’t the run-of-the-mill SLT model that you’ll see in the parking lots at every ranch supply store (or high-end shopping mall) in America’s heartland.

It’s a Ram 1500 HFE.

That’s HFE for High Fuel Efficiency.

The homeowners at Ram Trucks position a great deal of job in to thinking outside the box to develop a full-size pickup that offers the fuel economy of a V-6 midsize sedan. 

And as we found, its EPA ratings of 24 mpg combined (21 mpg city, 29 mpg highway) actually underrate its fuel efficiency at highway speeds.

The recipe

The heart of this truck is just what gives it the EcoDiesel badge: moms and dad firm Fiat Chrysler’s 3.0-liter turbodiesel V-6 engine, which you can easily include to simply concerning any sort of Ram trim level.

(It’s additionally available as an option on the Jeep Grand Cherokee luxury SUV, for that matter). 

Designed by Italian engine maker VM Motori, now a division of FCA, the EcoDiesel V-6 is rated at 240 horsepower and 4twenty pound-feet of torque in this application.

For the record, it is fitted along with a Selective Catalytic Reduction emission-aftertreatment system that injects a liquid urea solution in to the exhaust at explained times to convert harmful nitrogen oxides in to nitrogen and oxygen.

As well as its fuel tank, all of EcoDiesel Ram trucks have actually a divide tank holding several gallons of diesel exhaust fluid, or DEF—which Should be kept filled, or the truck won’t run.

DON’T MISS: 2016 pickup truck fuel economy roundup

What makes the HFE version of the Ram 1500 unique is the method it came with each other as a product.

Fiat Chrysler’s Ram truck group raided the proverbial portions bin for items to make this big truck more fuel-efficient.

It’s most likely rather like just what their grandparents did spine in the 1960s, looking for bolt-on portions to make their pony cars simply that little bit faster.

To get hold of there, they additionally booked a great deal of time in FCA’s wind tunnels.

They discovered that the a lot of aerodynamic configuration of the Ram full-size pickup was the middle model, the Quad Cab along with front-hinged short rear doors. 

The Quad Cab sits between the standard two-door normal cab, along with a single row of front seats, and the living-room-on-wheels Crew Cab.

Of course, Ram’s engineers decided on a 4×2 model, because the rear-wheel-drive-just version weighs much less and sits reduced to the ground compared to the 4×4.

All diesel Rams consist of grill shutters that activate at highway speeds to enhance aerodynamics.

And, regardless of engine, all of Rams have actually a ducktail spoiler integrated in to the tops of their tailgates to enhance airflow as it departs the vehicle.

Like all of big trucks, the Ram can easily be ordered in a dizzying array of trim levels. Discovering that weight (not to mention cost) would certainly be essential for the HFE, the engineers started along with the a lot of simple truck they could build.

Ram chose to forgo the cost, weight, and complexity of the normally optional air suspension, which may have actually allowed the HFE to hunker down closer to the road at highway speeds for reduced drag and presumably much better fuel economy. 

From there, the engineers looked at just what else could make the truck ever so slightly slipperier.

A tonneau cover was an obvious choice. however chrome operating boards?

They actually assistance to push air about the truck, Ram engineers found, after investigating multiple add-ons from their accessory catalog.

Even though they include weight, the operating boards are standard on the HFE.

As any sort of hybrid owner knows, wheels make a big difference. Looking at off-the-shelf items when again, the Ram engineers plucked 20-inch rims and tires from the high-end Big Horn and Lone Star trim levels.

But they discovered that the one-piece plastic-covered front fascia from the low-end Ram Express cut through the air much better compared to any sort of others bumper setup.
