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. Off-road hardware and the X31 package distinguish the AT4 from the SLE and SLT, while it skips some of the Denali's chrome and luxury trim. The AT4's standard off-road suspension and Rancho shocks make it capable on rough trails, though the ride is firmer than the Denali on pavement.
