Key Features of the 2027 GMC Terrain

15" diagonal Premium GMC Infotainment System

The 15" diagonal Premium GMC Infotainment System is one of the most important highlights of the Terrain cabin because it gives the interior a modern, command-center feel. GMC describes the system as a color touchscreen display designed to help drivers access, manage, and customize favorite in-vehicle entertainment. Its large vertical layout helps reduce the need to hunt through small menus, making it easier to interact with audio, navigation-related functions when equipped, smartphone connectivity, and vehicle settings. The available Google built-in integration adds another layer of familiarity for shoppers who already use connected services in daily life. Paired with an 11" diagonal Driver Information Center on the Elevation trim and beyond, the cabin feels digital without becoming complicated. This is especially helpful for drivers who regularly move between commuting, school pickups, appointments, and road trips, because the Terrain keeps key information visible and organized. The screen also supports the feeling that this is not simply a practical SUV; it is a refined GMC small SUV designed around convenience, customization, and confident everyday use.

60/40 split-folding rear seats

Versatility is a major reason shoppers choose a small SUV, and the Terrain answers that need with 60/40 split-folding rear seats, a rear cargo underfloor storage compartment, and front center console passthrough storage. With up to 29.8 cu. ft. of cargo volume behind the second row, the vehicle is ready for daily cargo while still carrying passengers comfortably. Fold the rear seats and the maximum cargo volume expands to 63.5 cu. ft. behind the first row, creating room for bulkier items without requiring a larger SUV. The split-folding design is especially useful because drivers can carry longer cargo on one side while keeping a rear seating position available on the other. The underfloor storage area helps keep smaller items tucked away, which is useful for valuables, emergency gear, charging cables, or items best kept out of sight. In a city environment where errands can stack up quickly, the Terrain makes the cabin easier to adapt throughout the day. It is the kind of detail that turns a compact footprint into a genuinely useful ownership experience.

1.5L Turbo 4-cylinder engine

Terrain features a power-packed 1.5L Turbo 4-cylinder engine paired with an 8-speed automatic transmission, giving the SUV the smooth, responsive character drivers expect from a modern GMC. The engine is rated at 175 horsepower, providing practical strength for merging, commuting, and carrying passengers or cargo. The 8-speed automatic transmission is designed to support smooth gear changes, which helps the SUV feel composed in changing traffic conditions. For shoppers who want added traction, Terrain is available with All-Wheel Drive. GMC also offers selectable drive modes, including Normal, Snow, Off-Road, Tow/Haul, and AT4-exclusive Terrain Modes, depending on configuration. These modes help the vehicle adapt to different surfaces and driving priorities. When properly equipped, Terrain can tow up to 1,500 lbs. with an available Trailering Package and In-Vehicle Trailering App, making it capable of handling smaller recreational items such as a light trailer, a small camper, or personal gear carriers. This performance package is not about excess; it is about balanced capability that fits everyday SUV expectations.

Over 16 standard safety and driver assistance features

Safety and driver confidence are central to the Terrain experience. GMC notes that the Elevation trim includes over 16 standard safety and driver assistance features, and the broader safety suite offers systems that help drivers stay more aware of nearby vehicles, pedestrians, bicyclists, and objects. Blind Zone Steering Assist can alert the driver and provide a brief, firm turn of the steering wheel when a potential crash is detected with a moving vehicle in the lane being entered. Forward Collision Alert can warn of a potential front-end collision with a detected vehicle and can also provide a tailgating alert. Front Pedestrian & Bicyclist Braking can help avoid or reduce the severity of a collision with a pedestrian or bicyclist detected directly ahead at certain speeds. Rear Cross Traffic Braking helps when reversing by alerting the driver and automatically providing hard emergency braking when needed for detected crossing vehicles. IntelliBeam can automatically turn high beams on and off according to surrounding traffic conditions at higher speeds. These features do not replace attentive driving, but they add valuable support.

AT4-exclusive Terrain drive mode

For shoppers who like a more adventurous look and added functional capability, the AT4 trim gives the Terrain a distinct personality. AT4 includes an AT4-exclusive Terrain drive mode, lifted ride height, red front recovery hooks, a front skid plate with steel underbody shield, LED fog lamps, and 17" Dark Machined aluminum wheels with all-terrain tires. These details work together to create a more rugged appearance while adding useful hardware for drivers who may encounter uneven roads, gravel paths, boat launches, or outdoor recreation areas. The front skid plate with steel underbody shield helps reinforce the purposeful character of the trim, while the red recovery hooks give the front end a signature AT4 visual cue. The available All-Wheel Drive system and selectable drive modes further support confidence in changing conditions. At the other end of the lineup, Denali focuses on refinement with heated and ventilated front seats, heated rear outboard seats, animated headlamps and taillamps, HD Surround Vision, Rear Camera Mirror, and signature Galvano chrome design cues. Together, the trims make it easy to choose the Terrain personality that best fits your lifestyle.
