Onyx Black 2025 GMC Sierra 3500HD Denali Ultimate 4WD represents the highest level of heavy-duty luxury, diesel power, and advanced towing technology GMC has ever offered. Powered by the legendary 6.6L Duramax Turbo-Diesel V8 paired with an advanced 10-speed automatic transmission and rugged 4WD system, this Sierra 3500HD is engineered to handle the most demanding towing and hauling tasks with ease while surrounding its occupants in premium comfort. Finished in stunning Onyx Black, it commands attention with the exclusive Denali Ultimate Vader Chrome grille, LED smoked amber roof marker lamps, a power sunroof, spray-on bedliner, and striking 20-inch Ultra-Bright Machined aluminum wheels that perfectly complement its bold, upscale appearance.
Inside, the Denali Ultimate cabin sets a new standard for heavy-duty truck luxury. Heated and ventilated front seats, heated rear outboard seats, premium materials throughout the interior, wireless charging, a premium Bose 12-speaker sound system, and a massive 15-inch multicolor Head-Up Display create an experience more comparable to a luxury SUV than a traditional pickup.
