Hennessey-tuned Jeep Grand Cherokee Trackhawk packs an insane 894kW

The Jeep Grand Cherokee Trackhawk is already one of the most potent SUVs on the market with its 522kW/873Nm 6.2-litre supercharged V8 but that hasn’t stopped Hennessey from tinkering with it.

Described as the “quickest accelerating SUV in the world”, the Hennessey Trackhawk churns out a mighty 894kW of power and an astonishing 1,354Nm of torque!

Thanks to the extra firepower, the Grand Cherokee Trackhawk does the century sprint in a supercar slaying 2.4 seconds and is capable of a top speed in excess of 321km/h. Hennessey says the SUV will run the quarter mile in just 9.6 seconds at 233km/h.

The insane power comes courtesy of the HPE1200 engine upgrade package that brings a massive 4.5-litre supercharger, an upgraded throttle body, a high-flow air induction system and long tube stainless steel headers. It also gains forged aluminium pistons and connecting rods along with ported cylinder heads and a new camshaft.

As a result of these upgrades, the engine develops 748kW of power and 1,208Nm of torque at the wheels when fed with 109-octane fuel.

No changes have been made to the SUV’s exterior, so it might be the ultimate sleeper!

Hennessey intends to build just 24 units of the HPE1200 tuned Jeep Grand Cherokee Trackhawk with prices starting from US$179,000 ($A251,438). The price includes the donor car as well as a unique feature which enables the Trackhawk to switch between rear- and all-wheel drive on demand. All the cars will also come with Nitto 555R 275/40-20 drag radial tyres.

In Australia, the Grand Cherokee Trackhawk is priced from $134,900 plus on-road costs.
