2025 GMC Sierra 3500 Denali

The 2025 GMC Sierra 3500 is the heavy-duty workhorse of GMC's pickup lineup, built to handle serious towing and payload duties. It squares off against the Ford F-350 Super Duty and Ram 3500 in the heavy-duty truck segment. The Sierra 3500 drives with the commanding presence you expect from a heavy-duty truck, though its size demands respect in tight spots. Inside, the cabin ranges from work-ready vinyl in base trims to the upscale materials of the Denali and Denali Ultimate. The Denali sits above the SLE, SLT, and AT4 in the Sierra 3500 lineup, trading some off-road hardware for the plushest cabin and most chrome. The Denali's real draw is its interior, with quilted leather seats and a 13.4-inch touchscreen that make it feel more luxury SUV than work truck.
