Chevrolet Colorado

For the vehicle of the same name sold in Thailand, see Isuzu D-Max.

The Chevrolet Colorado and its counterpart, the GMC Canyon, are General Motors' mid-size pickup trucks introduced in 2004 to replace the Chevrolet S10 and GMC Sonoma. Isuzu, which participated in the design the truck, began selling a version of the truck in late 2005 named the "i-Series". The Chevrolet Colorado was jointly designed by GM's North American operations, GM's Brazil operations, and Isuzu, based on the GMT355, itself the basis for the GMT 345-based Hummer H3. The vehicles are manufactured and produced at a GM plant in Rayong, Thailand and in Shreveport, Louisiana.

The Colorado/Canyon offer both manual and automatic transmissions. GM also offers either a rear-wheel drive or four-wheel drive drivetrain with standard, extended, and four-door crew cab bodystyles. Most models come with the 2.8L LK5 I4 engine as standard, but a more powerful 3.5L L52 I5 comes with the Z71 package on 4-door versions and is optional on all others. The 4-door Z71s also get the 4-speed automatic transmission standard. This package was later dropped in favor of LT2 and LT3.

A ZQ8 edition is available with a lower and more road-tuned "sport" suspension than the standard Z85 and comes with 17inch wheels, color-matched bumper and grille, and low profile fender flares. There is also a Xtreme edition of the ZQ8 which has a different front bumper, rear bumper, side skirts, fender flares, grille, headlights, and 18inch wheels.

For 2007, Colorado/Canyons offer new engines, which include the 2.9L LLV I4 and 3.7L L5R I5, new colors - Deep Ruby (Sonoma Red for the Canyon), Pace Blue (Sport Blue for the Canyon) and Imperial Blue (Midnight Blue for the Canyon), and new tires and wheels.

Colorado/Canyon U.S. sales peaked in 2005 at 163,204 units, surpassing the perennial segment leader, the Ford Ranger, by almost 35% and just 3.3% behind the new best-seller, the Toyota Tacoma. In 2006, however, while still leading the Ford pickup by 27.5%, Colorado/Canyon's sales lagged their Toyota competitor's by almost 34%.
