In recent years, the GMC Canyon pickup truck has stretched its dimensions and now falls into the intermediate category. This increase in size not only helps set the vehicle apart, it also appeals to a new clientele. The proud cousin of the Chevrolet Colorado is available in several configurations and comes with a choice of engines including: a 185-hp 2.9-litre four-cylinder, a 242-hp 3.7-litre five-cylinder and a 300-hp 5.3-litre V8.
