The GMC Terrain is a crossover SUV by American manufacturer General Motors under its GMC marque. Sharing its platform with the Chevrolet Equinox, the first-generation Terrain was built on GM's Theta platform, while the second-generation model is currently built on the Delta platform. The Terrain is the smallest GMC vehicle slotted below the Acadia. It also indirectly replaced the Pontiac Torrent which was often sold in the same dealerships prior to GM dropping the Pontiac brand.
