Terrain exterior features
A bold exterior design sets Terrain apart from other midsize crossover vehicles on the road with a refined, sculpted body that is accented with a sleek, yet angular, appearance. Eighteen-inch chrome clad aluminum wheels (standard on SLT-2 and available on SLE-2 and SLT-1 models) and 17-inch aluminum wheels (on SLE and SLT-1 models) emphasize a powerful stance, while chrome details add another level of style.
Inside the Terrain’s spacious cabin, premium interior features have been designed with high standards of functionality and materials that exude a commanding and structured feel. From the warm ambient lighting to the contrast stitching details, the Terrain is home to many comfort and convenience controls that make driving this vehicle seem effortless.
Powertrain details
GMC Terrain’s standard Ecotec 2.4L engine and available 3.6L V-6 feature fuel-saving direct injection and continuously variable valve timing. The 2.4L delivers 182 horsepower (136 kW) with an EPA-estimated highway fuel economy rating of 32 mpg (FWD models).
The 3.6L is rated at 301 horsepower (224 kW) and 272 lb-ft of torque (369 Nm) and uses lightweight components that contribute to the Terrain’s fuel efficiency while boosting horsepower. An integrated cylinder head/exhaust manifold design saves about 13 pounds compared to a non-integrated design, while a composite intake manifold saves about 5.5 pounds vs. an aluminum intake. Additionally, a lightweight structural front cover and high-strength connecting rods save additional weight.
An efficient six-speed automatic transmission is standard on all models and an “Eco” transmission mode on 2.4L-equipped models alters shift points to improve fuel economy.
