Miles Overview
The 2020 Sierra 2500HD is GMC's heavy-duty pickup, the one you cross-shop with the Ford Super Duty and Ram 2500 when you need serious towing and hauling. It drives like a big truck, with a commanding view and a ride that settles down once you've got weight in the bed. The cabin is roomy and quiet, and the available Denali trim adds upscale materials and heated, ventilated seats. You can get it as a regular, double, or crew cab, and the available MultiPro tailgate makes reaching into the bed a lot easier. The AT4 sits between the SLT and the Denali, and it's the one to pick if you want off-road hardware like a two-speed transfer case and hill descent control without giving up the upscale interior. Its 6.6L V8 produces 401 horsepower and 464 lb-ft of torque, paired with a six-speed automatic and four-wheel drive that handles heavy loads with confidence.
