As of 2015, small pickup trucks with the highest fuel efficiency ratings include the Chevrolet Colorado, GMC Canyon, Toyota Tacoma and Nissan Frontier. This goes for the two-wheel drive models only, as the four-wheel drive versions generally get fewer miles to the gallon.
The United States Department of Energy listed the 2015 Chevrolet Colorado, GMC Canyon and Toyota Tacoma as the most efficient small pickup trucks for that model year, as each had a combined fuel economy rating of 22 miles per gallon. While the two-wheel drive Toyota Tacoma was listed as one of the most efficient, the four-wheel drive version was listed among the least efficient, as it only achieved a combined fuel efficiency rating of 17 miles per gallon.
The 2016 Chevrolet Colorado and GMC Canyon have a slightly improved fuel economy compared to the 2015 versions, as both trucks get approximately 20 miles per gallon in the city and 27 miles per gallon on the highway. This is slightly less than the full-size 2016 Dodge Ram 1500, which is ranked as the most efficient pickup truck by Autobytel.com. This truck has a fuel economy rating of 21 miles per gallon in the city and 29 on the highway.
