Texas-based tuner-turned-automaker still knows a thing or a thousand about turning already-badass rigs into reality-warping monsters. Case in point, Hennessey’s latest edition of automotive insanity: the Jeep Grand Cherokee Trackhawk HP1200.
So, the Jeep Grand Cherokee Trackhawk already bends minds with its intolerance of physics and logic. Thanks to its 6.2-liter supercharged Hellcat V-8 engine that throws 707 horsepower at an eight speed automatic transmission and out to all four wheels, this 5,300-pound sled hurtles itself to 60 mph in 3.5 seconds and through the quarter mile in 11.6 seconds.
But for car nuts with a special type of insanity and aren’t satisfied with this — welcome to my club — Hennessey has your fix.
The Hennessey HP1200 upgrade massages this beasts heart with upgraded pistons, rods, ported cylinder heads and camshaft, long-tube stainless-steel headers, a 4.5-liter supercharger system that breathes 22 pounds of boost. This cranks the 6.2-liter engine to “11” and pushes its at-the-wheels output to 1,003 horsepower and 892 pound-feet of torque. Hennessey estimates this engine’s crankshaft output is 1,200 ponies and 1100 pound-feet.
To help harness this power, Hennessey also includes Nitto 555R drag radials sized 275/40R20 and a rear-wheel-drive switch so you can warm up the rear tires before hitting the quarter mile.
This all adds up to a supercar-killing — heck, a hypercar-killing — 2.3-second jump to 60 mph and a 9.66-second run in the quarter mile at 145 mph. Grocery lists will never be the same…
Dozen cage-free eggs, check!
Gallon of organic milk, check!
Grass-fed, grain-free, pasture-raised bison, check!
All-natural supercar ass-whoppin’, check!
You can land your own Jeep Grand Cherokee HPE 1200 Trailhawk for $179,000, which includes the $86,650 base Trackhack. Hennessey will produce only 24 examples, so you’d better get to ordering yours.
