Dealer Description
The 2020 GMC Sierra 2500HD AT4 is a rugged, off-road-ready heavy-duty pickup that blends premium features with serious capability. It’s powered by a 6.6-liter V8 Duramax turbo-diesel engine delivering a massive 445 horsepower and 910 lb-ft of torque. This particular setup is paired with a 6-speed automatic transmission, and features four-wheel drive for enhanced traction and towing performance. The AT4 trim adds off-road enhancements like skid plates, Rancho shocks, and a factory-installed 2-inch suspension lift, giving it a commanding stance and improved ground clearance. Exterior styling includes black chrome accents, red tow hooks, and bold AT4 badging. Inside, the cabin is upscale and functional, with leather-appointed seats, a large touchscreen infotainment system, and available tech like wireless charging and surround-view cameras. It’s built to haul, tow, and tackle tough terrain while keeping passengers comfortable and connected.
