The GMC Terrain is a mid-size crossover SUV. According to GM, it replaced the Pontiac Torrent which was 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. Although the preceding Pontiac Torrent had the same Theta platform, the Torrent was a rebadged version of the original Chevrolet Equinox from 2005–09, while GM decided to differ the look of the Chevrolet Equinox with its 2010 Terrain and still use the Theta platform.
The Terrain shares engineering with the 2010 Chevrolet Equinox. While the two vehicles use the same platform and drivetrain, the Terrain's body panels and standard features differ from those of the Equinox.
The 2010 Terrain debuted at the 2009 New York International Auto Show.
For the 2013 model year, the GMC Terrain receives the Denali trim which consists of more chrome trim and slightly improved interior quality, the 3.6L SIDI V6 that is shared with the 2012 Cadillac SRX in place of the optional 3.0L SIDI V6, and firmer front struts. The Denali also offers cross-traffic detection, blind-spot warning and a power passenger seat as options.
