The SRT-8 (Street and Racing
Technology V8) version of the Grand Cherokee debuted at the 2005 New
York International Auto Show. Powered by a 420 hp (313 kW) version of
the 6.1 L Hemi, it also features upgraded Brembo brakes, large dual
performance exhaust with polished tips (exiting out the middle of the
rear), Bilstein performance gas charged shocks and modified suspension
components, Mercedes-Benz NAG1 (WA580) 5-speed transmission, unique
NV146 transfer case, specially designed electronic all-wheel-drive
system and interior and exterior updates. A drive shaft from a diesel
application, fortified Dana 44 rear differential, and 11.2" (285 mm)
wide Goodyear tires in the rear (10" or 255 mm in the front) complement
the performance package. The sports tuned suspension allows the Jeep
SRT8 to hold 0.92 g on the skid-pad.
The 2006 model yielded a 0
to 60 mph time of 4.6 seconds, and a quarter mile dragstrip of 13.2
seconds at 104.1 miles per hour (167.5 km/h). This made the SRT-8 Grand
Cherokee the fastest accelerating vehicle within the SRT8 lineup (which
at the time included the Chrysler 300C, Dodge Charger, Dodge Challenger
and the now-discontinued Dodge Magnum), and second only to the SRT10
Viper among all SRT tuned vehicles. There is no electronic speed
governor employed, leaving the top speed rev-limited (revving to
redline in top gear) to 170 mph (270 km/h).
To achieve superior
on-road handling, off-road gear has been removed to make the SRT-8
lighter. The SRT-8 uses an NV146 transfer case, which uses an
electronic-applied clutch pack to transfer 0-50% of torque to the front
axle but has no low-range or manual controls. The front and rear
differentials are both open, with no limited-slip capability. Its ride
stance is significantly lower and the front fascia spoiler gives the
vehicle 7 inches (178 mm) of ground clearance. The Grand Cherokee SRT-8
was the first SRT vehicle to wear the Jeep emblem.
A total of 11,775 Jeep SRT8s were produced.
of 2014, the SRT8 is no longer that standard designation to indicate a
V8 powered perforamnce vehicle. Instead, "SRT" is a seperate
brand name for the Chrysler/Dodge line of performance vehicles.
The new JEEP SRT shows just how they mean business with the new

starters, the Grand Cherokee is no stranger to high-performance
variants with the SRT-8 model, so moving the range up-market should be
an easy move. Second, with machines like the Range Rover Sport SVR on
the market, Jeep could be looking to join the high-performance action.
Of course, the most damning piece of evidence found is the
trademark from FCA for the name “Trackhawk.” If you are familiar with
Jeep’s naming schemes, “Trailhawk” is a name used for hardcore off-road
models of the Cherokee and Grand Cherokee. Now it’s not a stretch to
see Jeep use the “Trackhawk” name for an ultra-high-performance variant.
Trackhawk will look fairly similar to the standard SRT Grand Cherokee.
The front retains the requisite Jeep grille, though it's been narrowed
a bit to make room for larger air intakes below. The Hellcat engine
creates a lot of heat, so designers needed to make sure the beast has
plenty of room to breathe. New LED fog lights have been integrated into
lower air ducts.
eight-speed automatic transmission developed by ZF will be the only
unit offered. While Dodge’s Hellcats are rear-wheel drive, the
Trackhawk will ship with all-wheel drive, and that’s where the
situation begins to get tricky. Car & Driver previously reported
the Grand Cherokee’s all-wheel drive system can’t handle the Hellcat’s
massive 707-horsepower and 650-lb-ft. output. Developing a new
all-wheel drive system for a low-volume model has been ruled out for
obvious cost reasons, so the eight-cylinder might have to be
electronically detuned before it can be dropped in the Grand Cherokee’s

cooled seats, rear entertainment system, media inputs, Bluetooth Paring
and many more options to keep all inside entertainment if they are not
entertained by 707 horsepower.
When launched, it will be on seriously powerful SUV to take on Range Rover’s Sport SVR, BMW’s X5M and Porsche’s Cayenne GTS.
Jeep Cherokee Hellcats will start rolling into showroom later in 2017
as they not only confirmed it a the show, but to official dealers in
the US back in August 2015.
While the blown 6.2-liter V8
delivers 707 ponies in both the Challenger and the Charger, we can't be
sure about the output it will deliver while installed on the
Mercedes-Benz ML-sourced platform of the flagship Jeep.

HellCat is named after a Grumman World War II fighter plane, used
mainly on aircraft carriers; many of its 2,000-hp Pratt & Whitney
engines (also used on Corsair and Thunderbolt) were made by Nash, the
car company that later joined with Hudson to form AMC, which was
purchased by Chrysler in 1987.
