The 2026 GMC Terrain is the perfect SUV for driving in Barrington, Illinois. Compact enough for easy maneuverability around downtown, rugged enough to handle changing seasons and off-road adventures, and offering a wealth of tech to keep you safe and connected, it’s the total package. Whether you prioritize everyday comfort, luxurious accommodations, advanced technology, or off-road capability, the Terrain offers a trim level designed to match your lifestyle.
Technology That Keeps You Connected
Every 2026 GMC Terrain shows off a 15” Premium GMC Infotainment System color touchscreen with Google Built-in. This means you can use Google Assistant for hands-free commands, access Google Maps for navigation, and manage entertainment—all from the center display without ever using your phone. Wireless smartphone compatibility also comes standard, so you can get your apps and playlists without the clutter of cords.
The 11” Driver Information Center gives you quick access to key vehicle data at a glance. It’s fully customizable to let you choose what stands out most, ensuring you’ve got the right data where you want it. Staying informed, entertained, and connected is straightforward and simple.
Interior Comfort and Cargo Versatility
The Terrain seats up to 5 passengers comfortably with 44” of front legroom and nearly 40” of 2nd-row legroom. Even with a full house of passengers, you’ll have 29.8 cu. ft. of cargo space for everyday stuff and a cooler, while folding the rear seats flat maxes that out at 63.5 cu. ft. The 60/40 split-folding rear seats and rear cargo underfloor storage compartment give you flexibility when hauling gear so nothing gets left behind, but your cabin stays clear.
Interior materials range from heated premium cloth seats on the entry-level Elevation trim to perforated leather front seats with heating and ventilation on the luxurious Denali. An available panoramic sunroof with a power sunshade adds an open, airy feel to every drive.
The AT4 Trim Level: Built for Extremes
For drivers who want to take the Terrain beyond the pavement, the AT4 trim is off-road-ready from the factory. With its lifted ride height, red recovery hooks, front skid plate with a steel underbody shield, and bold 17” Dark Machined aluminum wheels wrapped in all-terrain tires, it can take on the uncharted with ease.
The AT4-exclusive Terrain drive mode, combined with available all-wheel drive, gives you more confidence when conditions get rough. LED fog lamps and a distinctive exterior design make the AT4 a standout choice for adventure-minded drivers.
Safety Features That Support Every Drive
The 2026 GMC Terrain in Barrington, IL includes more than 16 standard safety and driver assistance features. This extensive list includes Enhanced Automatic Emergency Braking, Reverse Automatic Braking, and even Intersection Automatic Emergency Braking. This system watches out when you’re making a left turn and can stop if a vehicle approaches quickly. Blind Zone Steering Assist can steer you back to your lane if a vehicle approaches in your blind spot, while an HD Rear Vision Camera and Front Pedestrian and Bicyclist Braking is invaluable for tight spots, crowded lots, and school zones. Available HD Surround Vision and a Rear Camera Mirror provide even more visibility when you need it most.
Performance and Capability
The Terrain is powered by a 1.5L turbocharged 4-cylinder engine producing 175 hp and up to 203 lbs.-ft. of torque with all-wheel drive. That AWD system pairs with selectable drive modes—including Normal, Snow, Off-Road, and Tow/Haul—so you can tailor the drive to the situation at hand. The AT4’s Terrain Mode lets you take on rock crawls, ruts, and more obstacles. With the available Trailering Package, the Terrain can tow up to 1,500 lbs., making it capable of hauling smaller recreational trailers, jet skis, or light fishing boats.
