New 2028 GMC Acadia AT4 Review, Specs & Changes – The 2028 GMC Acadia AT4 stands out as the adventurous choice in GMC’s midsize three-row SUV lineup. It perfectly balances genuine off-road hardware with the spacious comfort and premium features American families expect. Building on the significant redesign introduced in recent model years, the AT4 trim adds lifted ride height, specialized all-wheel drive, and rugged styling that make it ideal for weekend trails, light overlanding, or confident driving in snow, rain, and rough roads across the United States. For buyers who want more than a standard crossover but still need room for seven passengers and cargo, the Acadia AT4 delivers a unique blend of capability and everyday usability.
What’s New for 2028 GMC Acadia AT4
For 2028, the GMC Acadia AT4 receives evolutionary upgrades focused on refining its off-road prowess and modern technology. Expect potential enhancements to the off-road suspension tuning for better articulation and ride quality, along with expanded drive modes and improved traction management.
Interior technology may see further integration of over-the-air updates and enhanced connectivity features. Safety systems could gain additional off-road-specific camera views or upgraded sensor technology. As a carryover from the current generation’s platform, the 2028 model emphasizes incremental improvements in durability, refinement, and user-friendly features rather than an all-new redesign.
What Makes This Trim Special?
The AT4 trim is GMC’s dedicated off-road-oriented variant, designed for drivers who occasionally venture beyond pavement without sacrificing family-hauling practicality. What sets it apart is the combination of Active Torque Control AWD with a twin-clutch rear axle that intelligently sends power to the wheel with the most grip, plus an off-road-tuned suspension with increased ground clearance and lifted ride height.
Exclusive touches include 18-inch dark machined aluminum wheels wrapped in all-terrain tires, protective skid plates, red recovery hooks, and a Terrain Mode within the Traction Select System. These elements give the Acadia AT4 a more aggressive stance and real-world capability that standard trims simply don’t offer, while still providing a composed on-road experience suitable for daily commuting and long highway trips.
2028 GMC Acadia AT4 Redesign
The current-generation Acadia introduced a bold, larger footprint with sleeker, more modern proportions compared to the boxier previous model. For 2028, the AT4 continues this evolution with subtle exterior refreshes that enhance its rugged identity. Expect darker accent trim, unique AT4 badging, and a more purposeful front fascia that emphasizes capability.
The overall design remains longer, wider, and taller than older Acadia models, delivering superior interior space and a commanding road presence. This “redesign DNA” carries forward, ensuring the 2028 AT4 maintains its distinctive look that bridges the gap between everyday family SUV and light-duty off-roader.
What Difference This Trim and Others
The Acadia AT4 sits between the value-focused Elevation and the luxury-oriented Denali trims. While the Elevation offers stylish looks and strong standard equipment at a lower price, the AT4 adds serious off-road hardware: Active Torque Control AWD (standard), lifted suspension, all-terrain tires, skid plates, and exclusive Terrain Mode.
In contrast, the Denali prioritizes premium leather, refined ride quality, larger wheels, and upscale interior finishes for smoother highway cruising and maximum comfort. The AT4 sacrifices some on-road plushness for better trail performance and a more adventurous aesthetic with blacked-out elements and recovery-focused details. If you need genuine light off-road ability and still want three rows of seating, the AT4 provides the best compromise in the lineup.
2028 GMC Acadia AT4 Interior, Features & Tech
Step inside the 2028 GMC Acadia AT4 and you’ll find a spacious, durable cabin tailored for active families. The three-row layout comfortably seats up to seven (with second-row captain’s chairs) or eight passengers, with significantly more legroom and cargo volume than previous generations—up to approximately 97.5 cubic feet with the rear seats folded.
AT4-specific interior touches include rugged yet premium Cloth/CoreTec upholstery with unique Forest Storm or similar color schemes accented by mahogany stitching for a sporty, outdoorsy feel. Higher trims add available leather and ambient lighting.
Tech highlights feature a large 15-inch touchscreen infotainment system with wireless Apple CarPlay and Android Auto, a digital driver display, and available Super Cruise hands-free driving assistance. Additional conveniences like a power liftgate, tri-zone climate control, and multiple USB ports make long family road trips across the U.S. more enjoyable.
Safety Features & Driver Assistance
GMC equips the Acadia AT4 with a robust suite of safety technologies designed to protect occupants on and off the road. Standard features typically include forward collision warning, automatic emergency braking, lane-keeping assist, blind-spot monitoring, and rear cross-traffic alert.
Off-road-specific aids such as hill descent control, hill start assist, and enhanced camera systems (including available surround-view) help drivers navigate tricky terrain confidently. Available Super Cruise provides advanced hands-free highway driving capability, reducing fatigue on long interstate journeys common in the United States. The combination of strong structure and modern electronics positions the AT4 as a safe choice for families who mix daily driving with occasional adventures.
2028 GMC Acadia AT4 Performance & Specs
Under the hood, the 2028 Acadia AT4 is powered by a potent 2.5-liter turbocharged inline-four engine producing 328 horsepower and 326 lb-ft of torque, paired with a smooth 8-speed automatic transmission. This powertrain delivers strong acceleration and responsive performance for merging, passing, and light towing.
The Active Torque Control AWD system provides excellent traction in varied conditions, while the off-road-tuned suspension and higher ground clearance improve stability on uneven surfaces. Maximum towing capacity reaches up to 5,000 pounds when properly equipped, making it suitable for small boats, campers, or trailers. Fuel economy is estimated around 20 city / 23-27 highway mpg depending on configuration, a reasonable figure for a capable three-row AWD SUV.
