Report: Next-Gen Colorado Will Only Be Available with 2.7-Liter Turbo-Four by Sebastien Bell April 22, 2020 Share Comments Chevrolet (and GMC, by extension) will not use any of the engines currently available on the Colorado/Canyon. In their place will be the 2.7-liter turbo-four, according to a report form Muscle Cars & Trucks. The report, which does not cite any sources, says that Chevy will get rid of the 2.8-liter Duramax diesel, the base 2.5-liter four-cylinder, and the 3.6-liter V6 for the next generation. MC&T also reports that the 10-speed automatic will also be the only transmission available to the small trucks. In the current Silverado/Sierra, the 2.7-liter engine that will apparently power the Colorado/Canyon makes 310 hp and 348 lb-ft of torque—about 40 more hp and torque than the 2.3-liter EcoBoost in the Ford Ranger. As you may have gleaned, the move also means that Chevy and GMC simply won’t offer a diesel-powered small truck in the USA when the next-generation arrives. Although GM still seems to have faith in diesel power, it seems to believe that it is better suited to bigger luxury fare like the Escalade than to smaller, economy vehicles like it is much of the rest of the world.
