Jeep Grand Cherokee SRT8
As the first Jeep® vehicle to wear the Street and Racing Technology (SRT) badge and the first four-wheel-drive SRT vehicle, the 2007 Jeep Grand Cherokee SRT8 was designed for superlative performance.
And it delivers: It’s the quickest, most powerful Jeep vehicle ever created, offering astonishing on-road and all-weather ability and power. With a 0-60-mph time in under 5 seconds — in wet or dry conditions — the 2007 Jeep Grand Cherokee SRT8 is quicker than competitors such as Porsche Cayenne Turbo and BMW X5.
Powered by a 6.1-liter HEMI® V-8 producing 420 horsepower (313 kW) and 420 lb.-ft. of torque (569 N•m), the 2007 Jeep Grand Cherokee SRT8 delivers a complete performance package, with exceptional ride and handling, world-class braking, race-inspired interior appointments and functional, performance-oriented 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.
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.
