The Ram 1500 EcoDiesel is obviously a more efficient vehicle than a Ford F-150 2,7 EcoBoost simply because it burns oil and can easily match and surpass manufacturer claimed figures.
In fact, in this comparative review by AutoGuide, the diesel Ram achieved an average figure slightly over what the manufacturer claimed, whereas the Ford didn’t come close to the official median, even though both cars were driven with a light foot and on the same route.
The Ram also feels more planted on the road, according to the reviewer, especially when hauling a trailer. Here, the Ford’s lower weight apparently makes it fidget and feel not as stable on uneven roads.
You do lose out on some modernity if you opt for the Ram, and the Ford beats it hands down for technology and usability too. The EcoBoost engine is also a much cheaper option to tick, whereas the $4,500 EcoDiesel option would take around five years to recoup it under normal driving conditions.
