The GMC Terrain comes with one of two engines. The standard 2.4-liter four-cylinder is rated at 182 horsepower and comes with a six-speed automatic, while the optional 3.0-liter V6 offers 264 hp and 222 pound-feet of torque, also routed through a six-speed auto. Front-wheel drive is standard, and all-wheel drive is optional across the lineup., , The GMC Terrain boasts a nice ride and handling combination, feeling like more of a substantial vehicle than its many small crossover rivals. Inside, the Terrain's cabin is impressively quiet, well built and earns top style marks. Fuel economy would seem to be a Terrain strong suit with the four-cylinder, but in real-world testing, we've found it to be merely average., , Features content is quite generous, with even the base model including such items as partial power front seats, a tilt-and-telescoping steering wheel, sliding and reclining rear seats, a rearview camera, OnStar emergency communications, satellite radio, Bluetooth phone and audio connectivity, and a touchscreen interface. With the latter two items, you can connect to Internet-based features like Pandora and Stitcher radio through a system GMC dubs Intellilink. Optional features like leather upholstery, automatic climate control, a lane-departure warning system, a navigation system and premium audio are available as you travel up the trim levels., , As a family hauler, the Terrain shines. Backseat accommodations are extraordinarily generous by default, and downright limousine-like when you slide the standard adjustable seat back. One minor disappointment is the Terrain's 64-cubic-foot maximum cargo capacity, which trails the class leaders despite this crossover's considerable dimensions.
