The Jeep Grand
Cherokee Trackhawk is one of the craziest SUVs on the market as the model has a
supercharged 6.2-liter V8 engine that produces 707 hp and 873 Nm of torque. It enables the model to rocket from 0-96
km/h in 3.5 seconds, before hitting a top speed of 289 km/h.
While most
consumers are happy with performance that can shame a Porsche Cayenne Turbo,
John Hennessey isn’t one of them. Instead, his company has introduced an
upgraded Trackhawk which produces an estimated 1,200 hp and 1,354 Nm of torque.
Thanks to the extra
power, the Grand Cherokee hits 96 km/h in 2.3 seconds and can
eventually top out at speeds in excess of 321 km/h. The model can
also run the quarter mile in 9.6 seconds at 233 km/h. It’s so fast
that Hennessey claims the Trackhawk is the “quickest accelerating SUV in the
world.”
In order to achieve
these insane numbers, the Grand Cherokee Trackhawk has been equipped with the
HPE1200 engine upgrade package which includes a massive 4.5-liter supercharger.
The package also adds forged aluminum pistons and connecting rods as well as
ported cylinder heads and a new camshaft. The company also installs an upgraded
throttle body, a high-flow air induction system and long tube stainless steel
headers – among other things.
Thanks to these
upgrades, the engine develops 1,003 hp and 1,208
Nm of torque at the wheels when running on 109 octane fuel. Hennessey says the
resulting driveline loss means the motor actually produces more than its quoted
output of 1,200 hp and 1,354 Nm of torque.
Regardless of the
final numbers, pricing starts at US$ 179,000 (£ 136,057/€ 154,575) and includes a
new 2019 Jeep Grand Cherokee Trackhawk. Production will be limited to 24 units
and all will come equipped with Nitto 555R 275/40-20 drag radial tires. The
model also has a unique feature which enables the Trackhawk to switch between
rear- and all-wheel drive on demand.
