At the heart of the 2026 GMC Terrain AT4 sits a 1.5-liter turbocharged 4-cylinder engine producing 175 horsepower, paired with an 8-speed automatic transmission. The AT4 trim takes things further with an AT4-exclusive Terrain drive mode alongside Normal, Snow, Off-Road, and Tow/Haul modes. Standard all-wheel drive adds confident traction across a wide range of driving conditions, and with an available Trailering Package, the Terrain AT4 can tow up to 1,500 pounds.

Inside, the Terrain AT4 features distinctive Forest Storm premium cloth and CoreTec seats with unique Mahogany piping and accents - a stylish nod to its rugged character. The 5-passenger cabin offers heated front seats and a heated steering wheel for added comfort. Practical touches like 60/40 split-folding rear seats, a rear cargo underfloor storage compartment, and front center console passthrough storage make the most of the available space, with up to 63.5 cubic feet of maximum cargo volume.

The 2026 Terrain AT4 centers its tech experience around a 15-inch diagonal Premium GMC Infotainment System with a color touchscreen. Google built-in enables hands-free assistance via Google Assistant and navigation through Google Maps, right on the center display. An 11-inch diagonal Driver Information Center keeps key vehicle data front and center, and available camera views - including HD Surround Vision and the Rear Camera Mirror - help you navigate parking and tight spaces with greater ease.

The Terrain AT4 comes loaded with over 16 standard safety and driver assistance features. Blind Zone Steering Assist can alert you and provide brief steering input when a potential crash with a vehicle in an adjacent lane is detected. Forward Collision Alert warns you of potential front-end collisions and includes a tailgating alert. Front Pedestrian and Bicyclist Braking operates between 5 and 50 miles per hour and can apply hard emergency braking when needed. Rear Cross Traffic Braking and IntelliBeam automatic high-beam headlamps round out the robust safety suite.

The 2026 GMC Terrain lineup offers three distinct trims to match a range of lifestyles. The Elevation starts the range with LED headlamps, heated front seats, and the full infotainment suite. The AT4 steps up with a lifted ride height, a front skid plate with steel underbody shield, red front recovery hooks, LED fog lamps, 17-inch Dark Machined aluminum wheels with all-terrain tires, and the exclusive Terrain drive mode. The Denali tops the lineup with a signature Galvano chrome grille, animated headlamps and taillamps, ventilated front seats, and 19-inch Midnight Silver machined-face aluminum wheels.

The 2026 GMC Terrain AT4 delivers an impressive combination of off-road readiness, thoughtful technology, and everyday practicality. With flexible financing options available, there's no better time to explore what this capable small SUV can do for you. Stop by and experience it for yourself.
