Miles Overview
The 2026 Sierra 2500 is GMC's heavy-duty pickup, built for serious towing and hauling with a range of trims from work-oriented Pro to luxury Denali Ultimate. It competes head-to-head with the Ford F-250 Super Duty and Ram 2500, offering comparable capability with a more premium cabin in upper trims. The Sierra 2500 drives with the confidence of a true heavy-duty truck, offering strong acceleration and stable towing manners, though its size demands respect in tight spots. Cabin space varies by cab configuration, but the Denali trims bring leather upholstery, heated and ventilated seats, and a large touchscreen with wireless smartphone integration. The AT4X adds Multimatic DSSV dampers, a 1.5-inch lift, and 35-inch mud-terrain tires over the AT4, making it the most off-road-ready Sierra 2500 short of a custom build. Its standard 6.6L V8 makes 401 horsepower and 464 lb-ft of torque, paired with a ten-speed automatic and four-wheel drive that handle heavy loads without breaking a sweat. The driver-selectable rear electronic-locking differential and Off-Road mode in the Traction Select System let you crawl over rocks you'd never attempt in a standard heavy-duty pickup.
