The 2015 unveiling of the Chevrolet Colorado gave the flailing intermediate pickup category a much needed boost. Not too big and not too small, the Colorado's dimensions are the answer to those in need of a pickup, but who don't necessarily want it to be a mastodon. Moreover, the fact that you can order it with a 181-horsepower, 2.8L four-cylinder diesel engine has managed to win over numerous buyers. The 200-horsepower four-cylinder and 305-horsepower V6 engines round out the offer.
