The 2026 GMC Sierra 2500HD Denali Crew Cab 4WD delivers heavy-duty capability combined with premium luxury and advanced technology. Finished in Onyx Black with a refined Atmosphere/Brownstone interior, this truck is powered by the legendary 6.6L Duramax V8 Turbo-Diesel paired with a 10-speed automatic transmission, providing exceptional torque, serious towing capability, and a 5-year / 160,000 km powertrain component warranty.
Equipped with the Denali Reserve Package, it features a power sunroof, rear camera mirror, and a 15-inch multicolor head-up display that projects key driving information directly into the driver’s line of sight. The cabin is further enhanced with power-retractable assist steps with LED perimeter lighting, premium floor liners with removable carpet inserts, and three years of SiriusXM for entertainment on every drive.
Built for demanding jobs, this Sierra includes the Gooseneck/5th Wheel Prep Package for serious trailering capability, a high idle switch for extended idling when operating equipment, and a tri-fold hard tonneau cover to keep cargo protected. With its combination of luxury Denali design, powerful Duramax diesel performance, and heavy-duty capability, the 2026 Sierra 2500HD Denali is built to handle tough work while delivering a premium driving experience.
