Dealer Description
CARFAX 1-OWNER VEHICLE, LOCAL TRADE, Ferman Luxury Pre-Owned Showcase, The 2025 GMC Sierra 2500HD AT4 is a heavy-duty truck that blends brute strength with upscale ruggedness, engineered for off-road prowess and serious towing capabilities. Positioned between the Denali and base models, the AT4 trim stands out with a bold, blacked-out grille, distinctive red tow hooks, body-color bumpers, and AT4-exclusive badging. It sits higher thanks to a factory-installed off-road suspension with Rancho monotube shocks and skid plates, making it trail-ready straight from the showroom. The 2025 model year brings subtle design updates and enhanced technology, refining the Sierra HDs blend of toughness and sophistication. Under the hood, the AT4 is powered by a standard 6.6-liter V8 gas engine delivering 401 horsepower and 464 lb-ft of torque, paired with a 10-speed Allison automatic transmission. For those demanding even more torque, the optional 6.6-liter Duramax turbo-diesel V8 produces 470 horsepower and a massive 975 lb-ft of torque. This allows the Sierra 2500HD AT4 to tow up to 22,500 pounds when properly equipped, making it an ideal companion for hauling trailers, boats, or work equipment. Inside, the cabin combines rugged durability with high-end features. Premium materials, heated and ventilated front seats, and available leather upholstery provide comfort in any climate. A massive 13.4-inch touchscreen infotainment system with Google built-in, wireless Apple CarPlay/Android Auto, and a 12.3-inch digital instrument cluster bring cutting-edge tech to the forefront. The AT4 also features a multi-camera trailering system, integrated trailer brake controller, and the versatile MultiPro tailgate, boosting both convenience and capability. With standard 4WD, hill descent control, and an off-road mode, the 2025 Sierra 2500HD AT4 is purpose-built for those who venture beyond the pavement. Whether towing through mountain passes or navigating remote job sites, it delivers confidence, luxury, and performance in a single commanding package.
