Shortly following the successful introduction of their Acadia crossover vehicle, GMC debuted with a smaller five-passenger model for 2010. Called the GMC Terrain, mid-sized crossover vehicle gave families a practical and fuel efficient for a competitive price. Constructed on the same platform as the Chevrolet Equinox, the GMC Terrain received a radically distinct and more upscale look than its corporate sister. Large chrome grille and rectangular-shaped projector-beam headlights are some of the notable design details indicative of a premium-oriented appearance. Equipped as either a front-wheel drive or an all-wheel drive version, the 2010 GMC Terrain was offered with a choice of two gasoline direct-injected engines.
The smaller base engine for the 2010 Terrain was a four-cylinder 2.4-liter double overhead cam powerplant that produced 182 horsepower and 172 pound-feet of torque. With a front-wheel drivetrain, the four-cylinder-powered GMC Terrain could travel up to 32 miles using a gallon of fuel on the highway. Presenting greater performance, the 3.0-liter V-6 generated 264 horsepower and 222 pound-feet of torque. A six-speed automatic transmission was used to manage engine momentum from both powerplants. Offered in SLE or SLT, the 2010 Terrain came with standout standard features such as 17-inch aluminum wheels, six-airbags, rear-view camera and OnStar.
The 3.0-liter V-6 added E85 compatibility in 2011 while the four-cylinder Terrain gained the feature in the following year. Also in 2012, a touch screen audio system featuring a seven-inch display became standard on all Terrains. A heightened sense of luxury was explored with the 2013 GMC Terrain through the addition of the Denali trim level. Featuring unique exterior and interior touches, the 2013 Terrain Denali came with eight-way power adjustable front seats, tuned suspension and a standard sunroof. For 2015, the GMC Terrain became one of many General Motors products to adopt OnStar with 4G LTE with built-in Wi-Fi hotspot.
