The 2025 GMC Sierra 2500HD Denali Ultimate represents the highest tier of refinement and capability in GMCs heavy-duty truck lineup. Built for those requiring substantial towing power while prioritizing interior luxury and advanced technology, this model pairs a Duramax 6.6L V8 Turbo Diesel engine with a 10-speed automatic transmission and a robust 4WD system. Its 2-speed active transfer case, hill descent control, and the X31 Off-Road Package enhance off-road performance and traction in demanding environments.
This Denali Ultimate edition showcases signature design elements such as the Vadar Chrome grille, LED smoked amber roof marker lamps, and a factory-applied spray-on bedliner featuring the GMC logo. Functional features include a 120-volt power outlet in both the bed and the instrument panel, LED cargo lighting, a power sliding rear window with defogger, and rear wheelhouse liners, all supporting the practical demands of daily use or jobsite readiness.
Towing and trailering technologies are comprehensive. This model includes the Gooseneck/5th Wheel Prep Package, trailer camera provisions with trailer viewing software, a trailer tire pressure monitoring system, Trailer Side Blind Zone Alert, and HD Surround Vision. A bed view camera further assists in aligning and monitoring trailer connections. Integrated ultrasonic front and rear park assist and Rear Cross Traffic Alert add to driver confidence during low-speed maneuvers.
Inside the crew cab, the Sierra 2500HD Denali Ultimate delivers premium comfort with Alpine Umber leather seating and a full suite of technology. Front seats offer heating and ventilation, while rear outboard seats are heated. The driver benefits from a multicolor 15-inch head-up display and an inside rearview auto-dimming camera mirror, both part of the comprehensive Technology Package. Wireless charging, wireless Apple CarPlay and Android Auto, a 12-speaker Bose Premium Series audio system, and SiriusXM with 360L keep connectivity and entertainment top-tier. Controls are ergonomically placed, including a manual tilt/telescoping steering column and a floor-mounted center console.
Convenience and security are enhanced through keyless open and start, a remote vehicle starter system, universal home remote, and the Unauthorized Entry Theft-Deterrent System. Rain-sensing wipers, a power sunroof, and deep-tinted glass further elevate the premium driving experience.
