Which full-size pickup truck gets the best gas mileage?
Full-size trucks are available in numerous engine and drivetrain configurations of automatic and manual transmissions, rear- and four-wheel drive, six- and eight-cylinders, which makes it difficult to sift through mileage numbers because all of these options affect gas mileage. But we did the hard work for you and here are the results: We compared rear-wheel-drive trucks in both six- and eight-cylinder configurations. Four-wheel drive is going to eat up gas and typically get worse mileage than rear-wheel drive.
According to federal gas mileage estimates for 2007 vehicles, the six- and eight-cylinder versions of the Chevrolet Silverado have the highest ratings among full-size, rear-wheel-drive trucks. Mileage estimates are listed below. The Silverado bested the Toyota Tundra by 1 to 2 miles per gallon in the city and on the highway.
Across the board, we noticed the difference is minimal when comparing a six-cylinder Ford to a comparable Toyota or Dodge, etc., and the same stays true when looking at eight-cylinder trucks. Of course, mileage in the “real world” is dependent on how you drive your truck, so even through the Chevy is rated at 22 mpg on the highway, if you’re heavy on the pedal or tow frequently, it may be harder to reach that estimate.
