The 2025 GMC Sierra 2500HD Denali blends heavy-duty capability with advanced technology and comfort features, making it a well-rounded option for those needing both power and refinement. Powered by the Duramax 6.6L V8 turbodiesel engine paired with a 10-speed automatic transmission, this 4WD truck is engineered for serious towing, off-road performance, and long-distance hauling. A 2-speed active transfer case and the X31 Off-Road Package, which includes hill descent control and skid plates, contribute to its off-road capability and all-terrain readiness.
Inside, the Denali trim delivers luxury through its Atmosphere/Brownstone leather interior, heated and ventilated front seats, and heated outboard rear seats. A power sunroof, power sliding rear window with defogger, and ambient LED lighting enhance the cabin environment. The floor-mounted center console provides organized storage, while the multicolor 15-inch head-up display projects essential driving data directly into the drivers field of view.
For trailering and cargo management, this Sierra is equipped with a gooseneck/5th wheel prep package, a spray-on bedliner with GMC logo, and dual 120-volt power outlets (one bed-mounted and one in the instrument panel). The bed view camera and trailer camera provisions, including Trailer Side Blind Zone Alert and trailer viewing software, contribute to safer and more precise towing. Rear wheelhouse liners and LED cargo area lighting further increase durability and visibility.
Technological highlights include a Bose Premium 7-speaker sound system, wireless phone projection, and wireless charging. The HD Surround Vision system, rearview auto-dimming mirror camera, and ultrasonic front and rear park assist offer improved awareness around the vehicle. The Safety Alert Seat and Rear Cross Traffic Alert provide additional layers of protection during daily driving and trailering.
Convenience features such as keyless open and start, push-button ignition, remote vehicle starter system, and universal home remote help streamline everyday operation. The inclusion of the Denali Reserve Package and Technology Package brings together GMCs top-tier features, including the signature chrome Denali grille and premium interior materials.
With OnStar services capability, SiriusXM with 360L trial subscription, and multiple USB ports including charge-only and data-enabled ports across both rows, the Sierra Denali caters to both connectivity and passenger comfort. Rain-sensing wipers and deep-tinted glass add functionality and privacy, while the trucks exterior is accentuated by LED smoked amber roof marker lamps and a polished exhaust tip.
