The Chevrolet Colorado (sharing mechanical commonality with the GMC Canyon) is a series of compact pickup trucks (first generation) and mid-size pickup trucks (since second generation) marketed by American automaker General Motors. They were introduced in 2004 to replace the Chevrolet S-10 and GMC S-15/Sonoma compact pickups. The Colorado is named after the U.S. state of Colorado, while the Canyon took its name from the deep chasm between cliffs.
