Here's how I averaged 31.5 mpg in a Ram HFE EcoDiesel

Few things could be more American than a bright red Ram pickup parked in front of Mount Rushmore. To get there and back on a single tank of fuel from the nearest major city, however, requires a collaboration of international proportions. This particular Ram is a 1500 HFE EcoDiesel, festooned with badges indicating the presence of an Italian turbodiesel V6 mated to a German eight-speed automatic. Some Rams are even built in Mexico, but this one only boasted a 27 percent Mexican parts content. A rather global truck, this one. It is the sum of its parts, but those bits and pieces were curated by a team of engineers in Michigan. At the risk of hipstering its history, the Ram HFE (High Fuel Efficiency) package was truly custom-tailored for one purpose: Achieving an EPA-rated 29 mpg on the highway, which is 1 mpg better than a standard Ram 1500 EcoDiesel. It did just that. No, it did better than that, but more on that in a minute. The Ram has stuck with its "son of big rig" styling for nearly 25 years; opting for the EcoDiesel V6 means you can fill up next to Peterbilts. My goal was to bypass truck stops entirely. I left Denver early in the morning and aimed to enjoy lunch with Washington, Jefferson, Roosevelt, and Lincoln looking over my shoulder before heading home for dinner. Mt. Rushmore is about 370 miles away from the northernmost truck stop within Denver, where I filled the Ram HFE's tank and headed northbound on Interstate 25 toward Wyoming and a series of smaller highways that roughly follow an old stagecoach route from Cheyenne to what is now Mt. Rushmore in South Dakota. The Ram was such a fuel miser that I could have driven an extra 50 miles each way and still avoided the pumps. It's beautifully stark country: the kind of desolate place where the FM radio does a lot of seeking; that's all the audio I had on board because the Ram HFE is decidedly lacking in comfort and convenience features. To get to an EPA-estimated 29 mpg highway figure, Ram engineers had to goals: To strip weight and improve aerodynamics. In the wind tunnel, the medium-size 4x2 Quad Cab with 20-inch wheels and the Ram Express trim level's one-piece front bumper proved the most aerodynamic configuration of the many flavors of Ram available. Interestingly, testing revealed that adding full-length tubular side steps and a tri-fold tonneau cover normally offered in the Mopar accessories catalog aid aerodynamics.

Ram goes all-in on SAE J2807 tow ratings [w/video]

Thanks to the Society of Automotive Engineers (SAE), when car shoppers look at horsepower and torque figures on vehicles, they know that all the automakers are calculating them the same way. However, that isn't the case when it comes to truck buyers and max towing capacity ratings because each company figures the value differently. That practice finally changes with the SAE's standardized J2807 system, though, and Ram Truck is the first one to apply the new test procedure to its entire light- and heavy-duty pickup range.
All models of the Ram 1500, 2500 and 3500 use the new, standardized rating for the 2015 model year, but buyers might not notice too much difference. According to the company, in 99 percent of cases the max towing weights are unchanged or even improve slightly from last year. That's a strong result compared to the 2015 Chevrolet Silverado and GMC Sierra that are seeing few increases but mostly decreases under the new testing procedure.
"For too long, an uneven playing field existed and towing capacities went unchecked. We're happy to be the only pickup truck manufacturer to align with the SAE J2807 towing standard across our pickup truck lineup," said Mike Cairns, director of Ram Truck engineering, in the company's announcement of the new specs.

GM also sheds parts from its pickups to boost payload ratings

The row between Ford and Ram over who boasts the best-in-class tow rating for heavy duty pickups has revealed a number of things. Chief among them is a report that Ford removes items like the spare tire, jack, radio and center console from its vehicles in a bid to lower its base curb weight and therefore keep the truck's gross vehicle weight rating down.
For those that need a refresher, GVWR is the vehicle's curb weight plus its maximum payload. A lower GVWR allows Ford to station its F-450 among the so-called Class III pickups, despite the fact that internally, it has the makings of a more brutish Class IV truck.
Ford explains away these deletions, saying a customer could order their vehicle in such a manner. It has also come to light that Ford is not the only automaker to engage in such practices.
