2025 GMC SIERRA 2500HD

The 2025 GMC Sierra 2500HD Denali Crew Cab 4WD combines serious heavy-duty capability with the premium comfort, technology and refinement of the Denali trim. Powered by the 6.6L Duramax Turbo-Diesel V8 paired with a 10-speed automatic transmission, this Sierra HD is built for demanding towing, hauling and year-round work while providing a highly equipped interior for everyday driving.

The Duramax diesel provides the heavy-duty performance expected from a Sierra 2500HD, while the two-speed electronic Autotrac transfer case, automatic locking rear differential and 3.42 rear axle provide additional capability when conditions become challenging. A GVWR of 11,350 lb reflects its heavy-duty configuration, while the Snow Plow Prep/Camper Package and high-idle switch further expand its work-ready versatility.

Trailering technology is extensive, including an integrated trailer brake controller, Hitch Guidance with Hitch View, in-vehicle Trailering App, Trailer Side Blind Zone Alert and Bed View Camera. StabiliTrak with Trailer Sway Control and Hill Start Assist provides additional confidence when towing, while HD Surround Vision supplies multiple camera perspectives around the truck.

The Denali interior combines premium materials with impressive comfort. Heated and ventilated front seats, heated second-row outboard seats, a heated steering wheel and dual-zone automatic climate control make this truck comfortable throughout the seasons. The 12-way power driver’s seat includes memory settings, while wireless charging and Bose premium audio add everyday convenience and refinement.

The Denali Reserve Package adds a power sunroof, Rear Camera Mirror and 15-inch multicolour Head-Up Display. The Head-Up Display projects important driving information into the driver’s field of view, while the Rear Camera Mirror can provide a wider unobstructed view behind the truck.

Technology is centred around GMC’s 13.4-inch Premium Infotainment touchscreen with Google built-in compatibility and navigation capability. Wireless Apple CarPlay and Android Auto integrate compatible smartphones, while the 12.3-inch reconfigurable Driver Information Centre provides a customizable digital instrument display.

Sierra HD Pro Safety includes Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, Following Distance Indicator and IntelliBeam automatic high beams. Front and Rear Park Assist, Rear Cross Traffic Alert and the Driver Safety Alert Seat provide additional awareness around this large heavy-duty truck.

Exterior equipment includes 20-inch high-gloss black aluminum wheels, chrome assist steps, a factory spray-on bedliner, animated LED projector headlamps, LED fog lamps and power-folding and extending heated mirrors with integrated turn signals and perimeter lighting. The GMC MultiPro Tailgate provides multiple configurations for loading, unloading and accessing the cargo bed.

As a heavy-duty vehicle, this Sierra 2500HD does not have standardized Canadian fuel-consumption ratings for its vehicle class.
