2026 GMC Sierra 2500 Pro

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. Vinyl seats, steel wheels, and a manual driver seat set the Pro apart as the work-ready entry point above the stripped-down base models. Its 6.6L V8, Gasoline makes 401 horsepower and 464 lb-ft of torque, paired with a ten-speed automatic and four-wheel drive for confident pulling power. The Pro comes with the Trailering Package standard, including a hitch, trailer brake controller, and trailering mirrors.
