GMC AT4 Lineup and Features

When you step into an AT4, you can feel right away that it was built with capability at its core. Every AT4 comes equipped with a factory lift for improved ground clearance, making it easier to tackle rough terrain without hesitation. You'll also get an off-road-tuned suspension that absorbs bumps and keeps you steady on uneven ground, while skid plates protect the underbody from rocks and debris. Advanced traction management systems allow you to switch between drive modes, such as Snow, Mud, Sand, or Tow/Haul, ensuring you're always prepared for whatever lies ahead. Many AT4 models also feature hill descent control, all-terrain tires with aggressive tread patterns, and four-wheel drive with a two-speed transfer case—giving you total control whether you're navigating steep trails, pulling through heavy mud, or cruising through icy conditions.

GMC gives you plenty of choices when it comes to finding the right AT4 for your lifestyle. The Sierra AT4 brings serious muscle to the table, offering available V8 power and towing capability that makes hauling trailers, boats, or campers feel effortless. The Canyon AT4 is more compact but no less rugged, with an available Off-Road Performance Package that includes skid plates, advanced suspension tuning, and even a locking rear differential. For those who want family space without giving up adventure, the Yukon AT4 adds seating for up to eight, Magnetic Ride Control for smooth handling on or off the road, and bold styling with black chrome trim. The Acadia AT4 rounds out the lineup with midsize SUV practicality, a twin-clutch AWD system that delivers grip exactly where you need it, and innovative interior storage solutions to keep all your gear organized. No matter which size or style you choose, every AT4 shares a tough, trail-ready personality with a refined GMC touch.

The AT4 stands out because it blends rugged performance with everyday comfort in a way that's hard to match. Inside, you'll find available leather-appointed seats, durable all-weather floor liners, and thoughtful design touches like unique AT4 badging and contrast stitching that make the cabin feel upscale yet adventure-ready. Technology is another significant advantage, featuring options such as an available Head-Up Display, a surround-view camera system that enhances parking or trail driving, and smartphone integration to keep you connected even when you're far from home. Safety doesn't take a back seat either—many AT4 models come standard with GMC Pro Safety features like forward collision alert, lane keep assist, and blind spot monitoring. Compared to other trims, the AT4 delivers a balance of off-road capability, advanced technology, and rugged styling that's hard to beat if you want a vehicle that's equally at home on city streets and dirt trails.

If you're ready to experience a vehicle that can handle rough trails just as easily as it handles your daily commute, the GMC AT4 lineup is the perfect fit.
