At the heart of the 2026 Terrain is a 1.5-liter turbocharged 4-cylinder engine producing 175 horsepower, paired with an 8-speed automatic transmission. Available all-wheel drive adds traction and confidence in changing weather conditions. Multiple selectable drive modes - including Normal, Snow, Off-Road, and Tow/Haul - give drivers the flexibility to adapt to different road conditions. When properly equipped, the Terrain can tow up to 1,500 pounds, making it capable of hauling smaller trailers, jet skis, or a compact fishing boat.

The Terrain's cabin is thoughtfully designed with comfort and versatility in mind. Standard heated front seats and a heated steering wheel make cold mornings more manageable, while available heated and ventilated front seats and heated rear outboard seats - found on the Denali trim - take passenger comfort to another level. The available panoramic sunroof opens up the cabin with expansive above-and-beyond views. Cargo flexibility is a clear highlight, with 60/40 split-folding rear seats, a rear cargo underfloor storage compartment, and up to 63.5 cubic feet of maximum cargo volume behind the first row.

The 2026 Terrain comes equipped with a 15-inch diagonal Premium GMC Infotainment System featuring a color touchscreen. Google built-in functionality means drivers can use Google Assistant to set reminders, reply to messages, and get directions, all without taking their hands off the wheel. Google Maps displays directly on the center display for seamless navigation. An 11-inch diagonal Driver Information Center keeps key vehicle data front and center. Available camera views, including HD Surround Vision and the Rear Camera Mirror, help make parking and maneuvering noticeably easier.

Drivers near Le Mars, Iowa, will appreciate the Terrain's impressive suite of standard safety and driver assistance features. Over 16 standard features come included, covering a broad range of driving scenarios. Blind Zone Steering Assist provides steering input when a potential collision with a vehicle in an adjacent lane is detected. Forward Collision Alert warns drivers of potential crashes and can issue a tailgating alert as well. Front Pedestrian and Bicyclist Braking can detect and respond to pedestrians or cyclists at speeds between 5 and 50 miles per hour. Rear Cross Traffic Braking automatically applies emergency braking when a cross-traffic collision is detected in reverse. IntelliBeam automatically adjusts high beams above 25 miles per hour based on surrounding traffic.

The 2026 GMC Terrain is available in three distinct trim levels, each offering a unique personality. The Elevation serves as the entry point, featuring LED headlamps and taillamps, heated front seats and steering wheel, and the full infotainment system. The AT4 steps up the adventure with an exclusive Terrain drive mode, a lifted ride height, a front skid plate with steel underbody shield, red front recovery hooks, and 17-inch dark machined aluminum wheels wrapped in all-terrain tires. At the top of the range, the Denali trim elevates the experience with perforated leather-appointed seating, heated and ventilated front seats, animated headlamps and taillamps, a signature Galvano chrome grille, HD Surround Vision, Rear Camera Mirror, and 19-inch Midnight Silver machined-face aluminum wheels.

The 2026 GMC Terrain strikes a meaningful balance between everyday functionality and upscale refinement. With three well-differentiated trims and a strong roster of technology and safety features, it's easy to find a Terrain that fits your lifestyle and priorities.
