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. Stepping up from the SLT to the AT4 adds the X31 Off-Road Package with Rancho shocks, skid plates, and Hill Descent Control, along with exclusive 20-inch black wheels and all-terrain tires. The 6.6L V8 makes 401 horsepower and 464 lb-ft of torque, paired with a ten-speed automatic and four-wheel drive, giving you confident pulling power whether you're towing a trailer or hauling gravel. The AT4's off-road suspension is tuned for dirt trails and rough job sites, so expect a firmer ride on pavement than the Denali's adaptive setup.
