Aggressive AT4 Styling with Trail-Ready Design
The Acadia AT4 stands apart from the standard Acadia lineup with a more rugged exterior appearance built around GMC's off-road-focused AT4 identity.

AT4 exterior highlights that stand out:
Turbocharged Power Built for Tennessee Roads
The 2026 Acadia AT4 delivers significantly more power than previous Acadia generations thanks to its 328-horsepower turbocharged engine. The added torque improves acceleration, highway merging, towing confidence, and low-speed climbing performance when traveling through hilly East Tennessee terrain.
Standard Active Torque Control All-Wheel Drive helps maximize traction during rain, gravel roads, or changing mountain weather conditions throughout the Tri-Cities region, keeping drivers confident in all four Tennessee seasons.
Standard AWD and Impressive Towing Capability
With Active Torque Control AWD standard and approximately 8.0 inches of ground clearance, the Acadia AT4 is built for Northeast Tennessee's varied terrain — from wet fall highways to mountain backroads near the Cherokee National Forest.
Its 5,000-pound towing capacity also makes it a practical choice for drivers who regularly haul trailers, boats, or outdoor equipment across East Tennessee and beyond.
