Miles Overview

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. Stepping up to the AT4 from the SLE adds off-road hardware like an automatic two-speed transfer case, skid plates, and Rancho shocks, plus unique styling inside and out. Its 6.6L V8 makes 401 horsepower and 464 lb-ft of torque, paired with a ten-speed automatic and four-wheel drive that give you confident traction on pavement and dirt alike.
