The Colorado was offered in three basic trim levels: Base, LS, and LT, while the Canyon was also offered in three trim levels, but with different names: Canyon, SLE, and SLT. This package was later dropped in favor of LT2 and LT3. The 4-door Z71s also get the four-speed automatic transmission standard. Most models come with the 2.8 L (171 cu in) LK5 I4 engine as standard, but a more powerful 3.5 I5 comes with the Z71 package on four-door versions and is optional on all others. GM also offers either a rear-wheel drive (4x2) or four-wheel drive (4x4) drivetrain with standard, extended, and four-door crew-cab body styles. The Colorado/Canyon trucks in the North American market offer both manual and automatic transmissions. The cooperation between GM and Isuzu to build a light-duty truck and offer it in North America returns to an original arrangement the two companies had in the 1970s with the Chevrolet LUV, a rebadged Isuzu Faster. All North American-market vehicles were manufactured by Shreveport Operations. Most vehicles for markets outside North America are manufactured at a GM plant in Rayong, Thailand. All Chevrolet, GMC, and Isuzu versions worldwide are based on the GMT355, itself the basis for the GMT 345-based Hummer H3. This North American model Isuzu shared North American powertrains, styling, and equipment with the Colorado/Canyon twins and differed from Isuzu's worldwide offering. In late 2005, Isuzu offered a version in North America called the Isuzu i-series. 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. 2007 Chevrolet Colorado LT Z71 (rear view)
