GM's small pickups, the Colorado and its GMC Canyon twin, are more maneuverable than full-sized trucks and better equipped than their Nissan and Toyota competitors. Buyers can choose a 200-hp four-cylinder or a 305-hp V6, both backed by a standard six-speed automatic. The ride is rather choppy, as befitting a pickup, but handling is responsive. Rear- and four-wheel-drive versions are available, as are extended and crew-cab body styles. Inside are the latest electronics, including the MyLink audio system. These are the first small trucks to offer forward-collision and lane-departure warnings, and a backup camera is standard. A 181-hp four-cylinder diesel is new. First-year reliability has been much below average.
