Vehicle Description
The 2023 GMC Sierra 2500HD AT4 is built for drivers who demand heavy-duty strength with off-road capability and premium refinement. Powered by the proven 6.6L Duramax Turbo-Diesel V8, paired with the Allison 10-speed automatic transmission, this truck delivers a commanding 445 horsepower and an incredible 910 lb-ft of torque. Whether you’re hauling, towing, or tackling rugged terrain, the AT4 is engineered to perform with confidence.
This 4WD Crew Cab with a 159" wheelbase offers both capability and comfort. With available towing up to 18,500 lbs (when properly equipped) and impressive payload ratings, it’s ready for serious work. The off-road-tuned suspension with Rancho shocks, skid plates, and a two-speed transfer case make the AT4 equally at home on the trails.
Inside, the AT4 blends rugged design with premium features. The cabin includes leather-appointed seating with exclusive Kalahari accents, a heated steering wheel, and heated/ventilated front seats for all-season comfort. A large touchscreen infotainment system with Apple CarPlay, Android Auto, and available navigation keeps you connected, while the premium Bose audio system delivers rich sound on every drive.
On the outside, the AT4 stands out with its bold black chrome grille, red recovery hooks, 18-inch machined aluminum wheels with all-terrain tires, and unique AT4 badging. LED lighting, a spray-on bedliner, and the innovative MultiPro Tailgate add both style and functionality.
Safety and confidence come standard, with available features like Front and Rear Park Assist, Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Alert, and HD Surround Vision camera system.
