Fuel economy has taken a bit of a back seat in the last few years in the full-size pickup market, with each manufacturer trying to one-up one another with ever higher horsepower, payload and towing numbers. The first fuel economy salvo was fired by Ford with their 3.5-liter twin-turbo V6 EcoBoost in their F-150. There were skeptics until it proved to be a big seller. Never one to simply follow, Ram’s response was a return to the diesel. Motor Trend put the new Ram to the mileage test and the results seem to back up Ram’s reasoning.
