New for 2015

The 2015 GMC Terrain gains two new exterior colors: Dark Sapphire Blue Metallic and Cypress Green Metallic. A built-in 4G LTE connection via OnStar is standard on all models (a subscription is available after a three-month trial).

Vehicle Summary

The 2015 GMC Terrain is a two-row crossover available in front- or all-wheel-drive configurations. It is sold in SLE, SLT, and Denali trims with the latter featuring different styling such as a chrome grille, satin-chrome accents, exclusive 18- or 19-inch wheel designs, contrast stitching, a soft-touch instrument panel, and a leather-wrapped steering wheel with mahogany wood accents.


Two engines are available in the 2015 GMC Terrain: a 2.4-liter I-4 with 182 hp and 172 lb-ft of torque and a 3.6-liter V-6 rated at 301 hp and 272 lb-ft. Both engines are paired to a six-speed automatic transmission. Fuel economy is decent at 22/32 mpg city/highway for front-drive I-4 models and 20/29 mpg with all-wheel drive. V-6-powered Terrains are less efficient at 17/24 mpg in front-drive guise and 16/23 with all-wheel drive. The crossover's heavy curb weight, which ranges from 3,853 to 4,204 pounds, hurts its acceleration, particularly in models with the I-4. Opting for the V-6 improves its acceleration but comes at the cost of gas mileage due to the six-speed automatic's slightly shorter gearing in this configuration. Handling is decent with good body control that doesn't sacrifice ride quality, which remains comfortable for long journeys.

Interior space is good in the 2015 Terrain, with up to 63.9 cubic feet of cargo volume with the rear seats folded. The second row also slides forward and back to increase room for passengers or cargo. Build quality is good in all models, with Denali variants trimmed in higher-grade materials to make it feel more upscale.

Optional safety aids include forward collision warning and lane departure warning.The 2015 GMC Terrain has a four-star overall safety score (out of a possible five stars). In IIHS evaluations, the crossover earned a good score on all testing categories and was awarded the Top Safety Pick rating (Good is the highest possible score).

What We Think

The 2015 GMC Terrain is a viable choice as a family crossover with a flexible cabin and upscale touches in Denali trim. In a comparison test against the Kia Sorento, we said that the crossover is an ideal for families with teenage children due to the sliding middle row, which expands cargo or passenger room. Performance, on the other hand, is average due to the crossover's heavy curb weight necessitating shorter transmission gearing when paired with the V-6 to offset the Terrain's heft. As a result, it has lower fuel economy ratings than some of its all-wheel-drive competitors.
