While pickups usually offer multiple configurations and engine options, the latest Colorado comes exclusively with a crew cab and 5.5-foot cargo bed. That being said, there are plenty of trim levels to choose from (WT, LT, Trail Boss, Z71, ZR2 and ZR2 Bison). All of them are powered by a turbocharged 2.7-litre four-cylinder engine delivering anywhere between 237-310 horsepower. The new ZR2 Bison has all the arsenal you need to be the king of the mountain.
