This 2024 GMC Yukon Denali Ultimate H650 takes GMC’s already ultra-premium full-size SUV and elevates it into something far more exclusive through Hennessey Performance engineering. This Onyx Black example combines the luxury and technology of the Denali Ultimate trim with the added performance of the Hennessey H650 package, transforming this family hauler into a 650-horsepower supercharged SUV. With a Whipple supercharger system, upgraded engine components, HPE calibration, and a throaty MagnaFlow exhaust system, this Yukon delivers the kind of straight-line performance few full-size SUVs can match while still retaining its exceptional comfort and long-distance usability. Finished in a sophisticated Onyx Black over Alpine Umber specification, this H650 offers an ideal blend of understated luxury and high-performance capability.

Exterior and Interior
The exterior of this 2024 GMC Yukon Denali Ultimate H650 is finished in Onyx Black and retains the bold, upscale styling that distinguishes the Denali Ultimate from lesser Yukon trims. Signature LED lighting, a massive chrome-accented grille, power assist steps, and 22-inch machined wheels give this SUV a commanding road presence, while subtle Hennessey exterior badging hints at the significant performance upgrades beneath the surface. The lowered stance created by the adaptive air suspension system pairs well with the aggressive soundtrack generated by the MagnaFlow stainless-steel cat-back exhaust system. Additional premium exterior touches include a hands-free power liftgate, panoramic power sunroof, and GMC’s advanced trailering technologies including Hitch Guidance with Hitch View and Trailer Side Blind Zone Alert. The interior of this 2024 GMC Yukon Denali Ultimate H650 showcases GMC’s flagship luxury SUV craftsmanship with Alpine Umber full-grain leather upholstery throughout the cabin. Heated and ventilated front bucket seats with massage functionality, second-row heated captain’s chairs, and a power-folding third row provide exceptional comfort for all passengers. The cabin also features a power-sliding center console, genuine wood trim, a heated steering wheel, and a rear-seat entertainment system. Technology remains a major highlight thanks to a 10.2-inch touchscreen infotainment system with wireless Apple CarPlay and Android Auto, a multicolor head-up display, Super Cruise hands-free driving capability, and an 18-speaker Bose Performance Series audio system. A serialized Hennessey plaque mounted within the cabin further emphasizes the exclusivity of this professionally upgraded SUV.

Engine
Under the hood sits a supercharged 6.2-liter EcoTec3 V8 upgraded by Hennessey Performance to H650 specification. Utilizing a 2.9-liter Whipple supercharger system, high-flow intercooling system, upgraded air induction, chromoly hardened pushrods, and HPE engine management calibration, this Yukon produces an impressive 650 horsepower at 5,500 rpm and 658 lb-ft of torque at 4,200 rpm. Power is routed through a 10-speed automatic transmission and a sophisticated 4WD system, allowing this nearly three-row luxury SUV to sprint from 0-60 mph in just 5.3 seconds while completing the quarter mile in 13.5 seconds. Additional upgrades include chassis dyno tuning, extensive road testing, and a MagnaFlow stainless-steel cat-back exhaust system that gives the H650 a far more aggressive tone than a factory Yukon Denali Ultimate.
