2015 Ram 3500 vs 2015 Ford F-350 mileage

Heavy duty trucks are exempt from EPA mileage measurements (maybe the testers figured that knowing exactly how much gas or diesel these monster trucks burn to do their jobs would make anyone looking into a truck for the first time cry) but that doesn’t mean that fuel efficiency doesn’t matter when you are hauling or working with your truck. What heavy duty truck is most fuel efficient? Keep reading to get the skinny on the 2015 Ram 3500 vs 2015 Ford F-350 mileage comparison.

This fuel efficiency test compared the top trims of each vehicle: the 2015 Ram 3500 Laramie Longhorn and 2015 Ford Super Duty F-350 King Ranch. Both of these diesel trucks had dual rear wheels and comparable power and torque. The Ford come out a little ahead on power, with 440 horsepower compared to the Ram’s 385 horsepower and they had very similar torque numbers at 860 pound-feet and 865 pound-feet respectively. The only major difference in the build of the vehicles was a different axle ratio.

The test was conducted and shared in the two videos below, but keep reading for simplified results.

The test was conducted on a highway loop of a total of just under 44 miles using a cruise controlled speed of 65 for most of the journey. Each vehicle towed an identical trailer and loaded down with a Ford Bronco which weighted about 7,300 pounds together and had four passengers.

In the end, the 2015 Ram 3500 averaged 14.2 mpg while the 2015 Ford F-350 DRW took in only 12.36 mpg.

In a competition between tow capacity or acceleration a different truck may come out on top, but in a straight mileage competition between these two dually trucks, the Ram took the lead.
