The midsize 2016 Chevrolet Colorado and GMC Canyon have broken through a new barrier by surpassing the full-size Ram 1500 EcoDiesel’s maximum rating of 29 miles per gallon. They now hold the title to the most fuel-efficient pickup trucks in America.
Detroit-based manufacturer General Motors on Nov. 9 announced that the U.S. Environmental Protection Agency had certified the trucks, when equipped with the new 2.8-liter Duramax turbo diesel engine, to reach 31 mpg on highway.
