Watch Hennessey’s Jeep Trackhawks Storm Past A Stock One

You’d have to be an absolute speed freak to buy the Jeep Grand Cherokee Trackhawk, an SUV so fast and powerful that it borders on ridiculous.

With a 6.2-liter supercharged V8 engine delivering 707 hp and 645 lb-ft (875 Nm) of torque, the Trackhawk can out-accelerate some supercars. Despite this, it can still carry a family in supreme comfort and with ample luggage space. For Hennessey Performance, the stock Trackhawk just isn’t enough.

The Texas tuner has developed two tuning packages for the SUV. The first, dubbed HPE850, adds a new supercharger pulley to lift boost from 11.6 psi to 14 psi. Engine tuning and a higher flow induction system result in a total of 852 hp and 845 lb-ft (1146 Nm). These upgrades allow the Trackhawk to hit 60 mph (96 km/h) in 2.9 seconds before sprinting down the quarter mile in 10.9 seconds at 124 mph (200 km/h).

Does anyone need an SUV as quick as the Trackhawk?

For the power hungry among us, Hennessey has also developed a HPE1000 package for the Trackhawk. As the name implies, this model pumps out 1012 hp and 969 lb-ft (1314 Nm) of torque thanks to a huge 4.5-liter supercharger, new fuel pump, enlarged injections, and a high-flow induction system. Naught to 60 mph passes in 2.7 seconds while the super-SUV hauls down the quarter mile in 10.7 seconds at 132 mph (212 km/h).

To show just how rapid its Trackhawks are, Hennessey lined up the HPE850 and HPE1000 against a stock Trackhawk in an epic three-way drag race. Unsurprisingly, they easily walk away from the standard model, despite it getting a slight head start.
