General Motors' mid-size pickup trucks - the Chevrolet Colorado and its counterpart, the GMC Canyon are introduced in 2004 to replace the GMC Sonoma and Chevrolet S-10. In late 2005 Isuzu began selling its own version, named the "i-Series". Also Isuzu participated in the design of the truck. The Chevrolet Colorado was jointly designed by GM's Brazil operations, GM's North American operations, and Isuzu, based on the GMT355. The vehicles are manufactured and produced at a GM plant in Shreveport, Louisiana and in. Rayong, Thailand.
 The Colorado/Canyon offer both automatic and manual transmission. GM also offers either a four-wheel drive or rear-wheel drive drivetrain with four-door crew cab, extended and standard bodystyles. Colorados come with a more powerful 3,460 cc (3.46 L; 211 cu in) L52 Straight-5 comes with the Z71 package on 4-door versions and is optional on all others but usually the most of Coiorado have 2,770 cc (2.77 L; 169 cu in) LK5 I4 engine as standard. 4-speed standard automatic transmission gets Coloradi  with 4-door Z71s.   This package was later dropped in favor of LT2 and LT3.
 A Coorado Z85 is a standard model, but ZQ8 edition is available with a lower and more road-tuned "sport" suspension and comes with color-matched bumper and grille, low profile fender flares and 17 inch wheels. There is also available a Xtreme edition of the Colorwdo ZQ8 which has a different front bumper, side skirts, grille, headlights,  rear bumper, fender flares and 18 inch wheels. From its predecessor, the Chevrolet S-10, Xtreme edition is basically a continuation of a trim package.
 For 2007, Calorado /Canyon was modernized and offered new colors — Imperial Blue (Midnight Blue for the Canyon) and Pace Blue (Sport Blue for the Canyon) and Deep Ruby (Sonoma Red for the Canyon), engines for Colorada /Canyon, which include powerful 3,653 cc (3.653 L; 222.9 cu in) L5R I5 and standard  2,923 cc (2.923 L; 178.4 cu in) LLV I4, and new wheels and  tires. Minor changes to the interior and grille for the Cloorado  LTZ and LT  models; the LS models kept the similar facelift ass the TrailBlazer in 2005. A Colotado with 5,328 cc (5.328 L; 325.1 cu in) LH8 V8 producing 300 hp (224 kW) and 320 lb•ft (434 N•m) is offered for model year 2009.
 In 2005 Colorafo/Canyon U.S. sales reached at 163,204 units, surpassing the perennial segment leader, the Nissan Frontier, Ford Ranger, by almost 35% and just with 3.3% behind the new best-seller, the Toyota Tacoma. However, in 2006, Coloardo/Canyon's sales lagged their Toyota competitor's by almost 34% and still leading the Ford pickup by 27.5%.
 The Colorato LT crew cabs are the only trims of the Colrado to have 6-passenger seating, however crew cabs being limited to LT trims which most other Chevrolet vehicles only offer front bucket seating with the trim.
 The Colarado and Canyon are expected to be completely redesigned and reengineered for the 2011 or 2012 model year. The aged Atlas 2.9 I4 and 3.7 I5 models will be replaced by the direct-injected base engines found in the new Equinox and Traverse (2.4 L LAF I4 and 3.6 L LLT V6), which are expected to come with the promise of better fuel economy. The new engines for Olorado are rated at 281 hp (210 kW) and 182 hp (136 kW). Six-speed transmission may also be viable with all three engines in the near future, and the 5.3 Vortec V8 is still expected to be an option and a promising even better fuel economy. Coloado will be built on the new GMT-700 platform, possibly being developed on a global platform in Brazil or Thailand.
