DESIGN
Trevor Creed, Senior Vice President - Design, Chrysler Group: "The Jeep Grand
Cherokee SRT8 was designed to evoke two important qualities: performance capability and
refinement. With subtle yet functional improvements inside and out, it redefines what a
performance SUV should be."
The 2007 Jeep Grand Cherokee SRT8's front fascia makes use of aerodynamic improvements to
reduce lift and drag, while providing sufficient air flow to cool the 6.1-liter HEMI V-8 engine. The front
fascia also helps increase brake-system cooling through integrated air ducts.
In the rear, a modified fascia incorporates an aggressive center cutout to accommodate dual 4-inch
exhaust tips. Sill extensions are another functional enhancement that help create downforce.
Inside the 2007 Jeep Grand Cherokee SRT8's cabin are power-adjustable, deeply sculpted
performance front seats complete with uniquely patterned performance suede inserts to hold
occupants during aggressive maneuvering. Interior accents include a carbon-fiber technical finish on
the leather-wrapped steering wheel, instrument-panel brow and shift knob, complemented by a
refined aluminum finishing on the center stack, shifter and door-switch bezels.
Full instrumentation includes a 180-mph (300-kph) speedometer, tachometer and temperature
gauges, all trimmed with a unique blue accent and located within a carbon fiber-trimmed binnacle.
ENGINEERING
Kipp Owen, Director - Street and Racing Technology: "The SRT-developed four-wheeldrive
system in the 2007 Jeep Grand Cherokee SRT8 coupled with its 6.1-liter, 420-horsepower
HEMI V-8 are an unbeatable combination, in terms of all-weather performance. But it doesn't
stop there: The 2007 Grand Cherokee SRT8 also benefits from SRT improvements including
Brembo brakes, a performance-tuned suspension and race-bred interior and exterior
enhancements."
SRT engineers created the first SRT vehicle with full-time four-wheel drive by creating a new transfer
case. They used the front half of a Jeep transfer case, chosen for its capability and light weight, and
mated it to the rear half of a heavier-duty case, chosen for its ruggedness and ability to house
electronic full-time, four-wheel-drive system components.
Under normal driving conditions, 5 percent to 10 percent of torque is directed to the front wheels, but
as much of the 6.1-liter HEMI V-8's torque that's needed can be directed forward when additional
traction or stability is required. Remaining torque is sent via a heavy-duty driveshaft to a Dana 44 rear
differential.
Providing horsepower and torque to the unique SRT four-wheel-drive system is a specially tuned
version of the new 6.1-liter SRT HEMI engine, which was developed by adding more cubic inches,
increasing the compression ratio and redesigning the cylinder head, intake and exhaust systems for
better flow and increased engine speed.
Power from the SRT 6.1-liter HEMI is sent through a special torque converter to an SRT-upgraded,
five-speed automatic transmission with specially calibrated driver-selectable Auto Stick, which offers
fully automatic or manual shift selection.
Chassis setup for the 2007 Jeep Grand Cherokee SRT8 employs SRT-tuned dampers, unique sway
bars and specially tailored spring rates and suspension bushings. Front suspension knuckles were
redesigned to accommodate high-performance braking and steering systems. The ride height of the
2007 Jeep Grand Cherokee SRT8 is 1 inch lower than the Jeep Grand Cherokee, which lowers
aerodynamic drag as well as the center of gravity, and contributes to the vehicle's stability and
aggressive stance.
With an optional hitch package available from Mopar®, the 2007 Jeep Grand Cherokee SRT8 is
capable of towing up to 3,500 pounds.
The braking system of the 2007 Jeep Grand Cherokee SRT8 features four-piston performance brake
calipers developed by Brembo, finished in gloss black. While braking, these calipers work with 360
mm x 32 mm vented rotors up front, with 350 mm x 28 mm vented rotors in the rear.
