Three configurations are available for the GMC Canyon: standard cab, extended cab and crew cab. Extended-cab and crew-cab models feature four doors; crew-cab Canyons have four standard-sized doors and a 60/40-split-folding rear seat that can seat three adults, while extended-cab versions offer two small reverse-opening doors and rear jump seats. Canyon crew cabs haul loads with a 5-foot bed, while the other two configurations get the job done with a bed that measures 6 feet., , Three trim levels are available: Work Truck (WT), SLE and SLT. WT models offer features like air-conditioning, cruise control and an AM/FM stereo. The Canyon SLE model adds an improved stereo and a more extensive options list, though power accessories are an extra-cost option on regular-cab SLEs (standard on extended-cab SLEs). The SLT steps it up with leather upholstery and power seats. There are also two optional suspension packages. The Z71 suspension improves the off-road performance of 4WD trucks, while the ZQ8 package for 2WD trucks enhances on-road handling and grip., , GMC Canyon buyers have a choice of three engines. A 2.9-liter inline four-cylinder produces 185 horsepower, and is standard on WT and SLE models. It comes with either a five-speed manual or a four-speed automatic. The 3.7-liter inline five-cylinder is more robust, offering 242 hp. Both a five-speed manual and a four-speed automatic transmission are available. The available 5.3-liter V8 cranks out 300 hp. Two-wheel drive and four-wheel drive are offered; the 4WD system has a dual-range transfer case and push-button controls., , The GMC Canyon has met with middling reviews from our editors. Its interior has been criticized for being below average in build and material quality. Its engines, too, have been panned as lackluster, though the optional V8 is possibly the most enjoyable engine in the compact truck segment. In consumer reviews, owners have praised the truck for its stylish exterior and quiet ride, but have expressed reservations about its build quality. In sum, unless you can't live without V8 power in your midsize truck, there are better choices.
