Hennessey Jeep Grand Cherokee Trackhawk Makes 1,200 HP And Runs Quarter-Mile in 9.66 Seconds

When you think of a Jeep Grand Cherokee Trackhawk, you think of a big Hemi under the hood and incredible power and performance. Add a Hennessey badge, and you think ridiculous power.

With 707bhp from its Hellcat 6.2-liter supercharged V-8 under the hood, the Grand Cherokee Trackhawk is already ridiculously quick SUV with impressive 11.7-second quarter-mile time.

But for Hennessey Performance, the stock Trackhawk just isn’t enough. Hennessey dials things up with a 4.5-liter supercharger, upgraded pistons, rods, ported cylinder heads, camshaft upgrade, and long tube stainless steel headers.

Hennessey’s HPE1200 Jeep Trackhawk performance upgrade is extensive, to say the least. With 22 psi of boost pressure, the HPE1200 produces 1003 bhp and 892 lb-ft of torque at the wheels. Factoring in a 20 percent driveline loss, this equates to more than 1200 bhp and 1100 lb-ft at the motor.

The Jeep Grand Cherokee Trackhawk is already verging on being silly, but with the HPE1200 package from Hennessey, HPE1200 Trackhawk runs 0-60 mph in 2.3 sec & 9.66 sec. @ 145 mph in the ¼ mile. If you’re wondering about top speed, it’s 200+ mph.

If you want Hennessey HPE1200 Trackhawks, it’s going to cost you. A lot. While the stock Trackhawk starts at $87,695, the base price for Hennessey Trackhawk is a cool $179,000. However, the price includes a standard Grand Cherokee Trackhawk to undergo the modifications.

Too much? Then again, how many other SUVs can run a sub-10-second quarter mile? Not to mention this build is guaranteed with 1 Year / 12,000 Mile Limited Warranty.

Now check out how this flying brick performs next to a stock McLaren 720S. This is what happens when Hennessey adds nearly 500 horsepower to an already blistering-fast machine.
