• For the 2004 model year, the Chevrolet division of General Motors introduced the Colorado, a mid-size pickup truck. The 2005 Colorado is thus the vehicle's second model year. Although several of its versions--determined by trim, rear-wheel (2WD) or four-wheel (4WD) drivetrain, and bed and cab size--have 2.8-liter engines, two versions of the truck have 3.5-liter engines instead. They are the LS Z71 Crew Cab and the LS ZQ8 Crew Cab.
