The Fuelly website lets users search for fuel economy ratings for vehicles, including the RAM 2500 and Chevrolet Silverado pickups. These ratings are collated from reports from owners, since the Environmental Protection Agency does not provide fuel efficiency ratings for these models.Continue Reading
The typical fuel economy reported by Fuelly for a 2014 RAM 2500 fitted with the 6.4-liter HEMI engine is 13 miles per gallon, as of March 2015. In comparison, a Chevrolet Silverado 2500 fitted with the comparable 6-liter V8 engine also gets 13 miles per gallon. In addition to searching for vehicles by model and engine type, Fuelly allows users to specify additional features of vehicles for comparison. Features such as the cab style and four-wheel drive can significantly affect the fuel economy of pickup trucks such as the Ram 2500 and Silverado, so specifying these features allows for a more accurate comparison between models.
Under current U.S. law, trucks over 8,600 pounds of gross vehicle weight are exempted from the Environmental Protection Agency's fuel economy and rating standards. The RAM 2500 and Chevrolet Silverado are both exempt under these regulations, as the gross vehicle weight of both trucks is well in excess of 9,000 pounds in most trims.Learn more about Car Makes & Models
