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 Denali Ultimate is the top Sierra 2500 trim, adding the Duramax diesel, massaging seats, and exclusive Vader Chrome grille over the standard Denali. Its 6.6L V8 makes 470 horsepower and 975 lb-ft of torque, routed through a ten-speed automatic and four-wheel drive that handle heavy trailers with ease. The standard Technology Package brings a 15-inch head-up display and a rear-camera mirror, both unique to this trim.
