The Chevrolet Colorado, and its counterpart, the GMC Canyon, are series of compact and later mid-sized pickup trucks marketed by American automaker General Motors. They were introduced in 2004 to replace the Chevrolet S-10 and GMC S-15/Sonoma compact pickups. It is named for the U.S. state of Colorado. The Chevrolet Colorado and its twin, the GMC Canyon were jointly designed by GM's North American operations, GM's Brazil operations, and Isuzu, which began selling its own version worldwide in 2002. In late 2005, Isuzu offered a version in North America called the Isuzu i-series. This North American model Isuzu shared North American powertrains, styling, and equipment with the Colorado/Canyon twins and differed from Isuzu's worldwide offering. All Chevrolet, GMC, and Isuzu versions worldwide are based on the GMT355, itself the basis for the GMT 345-based Hummer H3. Most vehicles for markets outside North America are manufactured at a GM plant in Rayong, Thailand. All North American-market vehicles were manufactured by Shreveport Operations.
