The vehicle stands out with red front recovery hooks and a protective front steel skid plate that guards critical underbody components. Standard 17-inch dark machined aluminum wheels wrapped in all-terrain tires provide the necessary grip and durability for gravel paths and muddy trails.
Uncompromising Safety – Advanced Driver Assistance

A massive 15-inch infotainment screen dominates the dashboard, running on a Google Built-in operating system for native access to Maps and Assistant. Drivers benefit from a standard 11-inch digital gauge cluster that is fully customizable to display navigation, speed, and vehicle vitals. Wireless Apple CarPlay and Android Auto come standard, ensuring that your digital life stays connected without the clutter of cables.
Interior Versatility – Smart Space Management
Maximum cargo utility is achieved through a 60/40 split-folding rear seat configuration that expands the storage area to a significant 63.5 cubic feet. The cabin features durable CoreTec seat upholstery and AT4-specific interior accents that balance premium comfort with easy-to-clean practicality. Small-item storage is enhanced by a pass-through center console and multiple dedicated bins for passenger gear.
Fuel Efficiency – Optimized for Long Journeys
Respectable fuel economy ratings allow the AT4 to remain a viable daily driver despite its off-road enhancements and standard AWD. The vehicle is estimated to deliver 24 MPG in the city and 28 MPG on the highway, balancing its rugged capabilities with efficient fuel consumption. Active Noise Cancellation is also standard, ensuring the cabin remains quiet and refined regardless of road conditions or wind resistance.
Verdict: A Premium Off-Road Specialist
The 2026 GMC Terrain AT4 is a compelling choice for buyers who want the rugged capability of a truck in a maneuverable compact SUV package. With its standard AWD, lifted suspension, and class-leading 15-inch touchscreen, it offers a superior blend of tech and toughness. While it commands a higher entry price than the base Elevation trim, the added protection of steel skid plates and the utility of Terrain Mode justify the investment for adventure-seekers.
