A new era of the GMC Yukon Denali Ultimate is heralded - thanks to the Hennessey H650 package. With this, the already impressive SUV mutates into a real powerhouse and makes hearts beat faster. But what is behind the H650 package? First, there's the power upgrade of GM's popular 6,2-liter V8 (L87 EcoTec3). With the help of Hennessey's 3,0-liter compressor, an air intake system, a high-performance intercooler and a special crankcase ventilation, Hennessey gives the Denali a decent power boost. And to make the engine more stable, chrome-molybdenum pushrods were also installed. In addition, the control unit received new software in the form of Hennessey's own HPE chip tuning.

The performance of the Yukon Denali Ultimate is increased with the tuning package from the former 420 to an impressive 650 hp at 5.500 rpm. The maximum torque also increases to 892 NM at 4.200 rpm. The upgrade is rounded off by a stainless steel sports exhaust system from the catalytic converter with standard tailpipes, which not only ensure improved performance, but also an incomparable sound.

But the H650 package goes one step further and also comes with all the necessary seals and fluids. Incidentally, a subtle detail in the engine compartment is a special plaque with a consecutive number. There are also Hennessey logos on the outside of the vehicle to indicate the upgrade. And those looking for even more can opt for additional performance wheels and an upgraded braking system. The rims are available in glossy black or polished silver and are 22-inch in size.

Warranty: 3 years or 36.000 miles

The icing on the cake of the H650 package is the limited 3-year or 36.000 miles (approx. 58.000 km) warranty on the conversion. This allows Yukon Denali Ultimate owners to get into their tuned SUV with peace of mind. However, the H650 supercharger upgrade is only available for the 6,2L V8 version, but it's also offered for the Escalade, Yukon, Suburban and Tahoe models.

A feature of the H650 software is that it permanently removes General Motors' "Cylinder Deactivation" and "Auto Start/Stop" features. Overall, the Hennessey H650 package creates a perfect symbiosis of luxury and performance that catapults the GMC Yukon Denali Ultimate to new heights.
