The GMC Terrain is a compact crossover SUV that replaced the Pontiac Torrent, sold in the same dealerships prior to GM dropping the Pontiac brand,. Like the Torrent, the Terrain is based on the Theta platform. The Terrain slots below the Acadia as GMC's smallest SUV. The Terrain shares engineering with the 2010 Chevrolet Equinox. The 2010 Terrain debuted at the 2009 New York International Auto Show. Like the preceding Pontiac Torrent, the Terrain will be sold in Mexico.
