2026 GMC Terrain AT4

The 2026 GMC Terrain AT4 earns its off-road credentials with a turbocharged 1.5-liter four-cylinder engine paired with an eight-speed automatic transmission. All-wheel drive comes standard, giving drivers confident traction on unpredictable terrain. Available Hill Descent Control helps you navigate steep grades with precision, while AT4-exclusive selectable Terrain drive mode — with up to five different drive modes — lets you tailor the vehicle's response to whatever conditions lie ahead. A factory-installed trailer hitch and wiring harness also come standard, so you can tow your favorite gear with ease.

Step inside the Terrain AT4 and you'll find a thoughtfully designed cabin that blends rugged capability with everyday comfort. Cloth and CoreTec seating material provide a durable yet refined feel, and heated front seats and a heated steering wheel keep you comfortable when the temperature drops. The interior maximizes versatility with 60/40 split-folding rear seats, an underfloor storage compartment, and center console passthrough storage for added cargo flexibility. An available panoramic sunroof opens up the cabin and lets passengers soak in wide, sweeping views from every seat.

The Terrain AT4 centers its tech experience around a standard 15-inch diagonal Premium GMC Infotainment System touchscreen, designed to help you access, manage, and customize your in-vehicle entertainment with ease. Google Built-In compatibility lets you use Google Assistant and Google Maps directly on the touchscreen, so you can get directions, reply to messages, and control select vehicle functions without picking up your phone. An 11-inch diagonal Driver Information Center keeps key vehicle data right in your line of sight. Available wireless smartphone charging keeps your compatible device powered up on longer drives, while an available AutoSense power liftgate lets you open the rear hands-free — a welcome convenience when your hands are full.

The 2026 GMC Terrain AT4 comes equipped with more than 16 standard safety and driver assistance technologies, providing confidence-inspiring coverage on every drive. Standard features include Forward Collision Alert and Adaptive Cruise Control to help manage highway driving with greater ease. Available camera technology includes up to eight different camera views, High Definition Surround Vision, and a Rear Camera Mirror with washer — tools that make navigating tight parking lots and tricky situations far less stressful. These systems are engineered to support attentive drivers, adding an extra layer of awareness wherever the road takes you.

The 2026 GMC Terrain is available in three distinct trim levels: the Elevation, the AT4, and the Denali. The Elevation serves as an excellent entry point, offering a well-rounded feature set including the 15-inch touchscreen and over 16 standard safety and driver assistance technologies. The AT4 builds on the Elevation's foundation with off-road-specific upgrades, including a lifted ride height, red front recovery hooks, a front skid plate with steel underbody shield, 17-inch Dark Machined aluminum wheels with all-terrain tires, and AT4 badging. The Denali caps the lineup with premium luxury touches, including animated LED headlamps and taillamps, heated and ventilated front seats, heated rear outboard seats, High Definition Surround Vision, a Rear Camera Mirror, and 19-inch Midnight Silver machined-face aluminum wheels.

The 2026 GMC Terrain AT4 strikes a compelling balance between off-road readiness and everyday sophistication. Whether you're tackling rough trails or cruising through your daily routine, this small SUV is engineered to keep pace with your life — confidently and in style.
