Jeep Introduces All-new 2006 Grand Cherokee SRT8: The Quickest, Most Powerful Jeep Vehicle Ever

The all-new 2006 Jeep Grand Cherokee SRT8 combines capability, utility and distinctive style with Street and Racing Technology's (SRT) balanced approach to performance, resulting in the quickest, most powerful Jeep vehicle ever created, and the ultimate performance sport-utility vehicle.

Powered by a 6.1-liter HEMI producing 415 horsepower (85 more horses and 25 percent more power than the 5.7-liter HEMI-equipped 2006 Jeep Grand Cherokee) and 410 lb-ft of torque, the all-new 2006 Jeep Grand Cherokee SRT8's performance numbers include 0-60 mph in under 5 seconds, 0-100-0 mph in the low 19-second range, and 60-0 mph braking distance of approximately 125 feet.

"When we set out to create the first Jeep-branded SRT vehicle, the 2006 Jeep Grand Cherokee presented us with an incredibly capable starting point," said Dan Knott, Director - Street and Racing Technology, Chrysler Group. "With an infusion of SRT DNA, the 2006 Jeep Grand Cherokee SRT8 is the new benchmark performance SUV. It has the raw power to outperform the Porsche Cayenne Turbo, while providing exceptional ride and handling, world-class braking, race-inspired interior appointments and functional, performance-oriented exterior enhancements."

Four-Wheel-Drive System

To create the first SRT vehicle with full-time four-wheel drive, SRT engineers developed a drive system that was lightweight, yet robust and reliable enough to handle massive amounts of horsepower and torque from the 2006 Jeep Grand Cherokee SRT8's powertrain.

Under normal driving conditions, from 5 percent to 10 percent of torque is directed to the front wheels, but as much of the 6.1-liter HEMI's torque as needed can be directed forward when additional traction or stability is required. Remaining torque is sent via a heavy-duty driveshaft designed for the European Jeep Grand Cherokee diesel model, to a Dana 44 rear differential upgraded with a larger ring gear within a new axle housing.

Powertrain

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. Inspired by the original family of HEMIs, the SRT 6.1-liter HEMI employs the namesake hemispherical combustion chambers that provide power and efficiency, while retaining classic HEMI visual cues including the orange-painted cylinder block and black valve covers.

Engine breathing was increased with new higher-flow cylinder heads, a specially designed intake manifold and fresh-air induction system (which allows water-fording capability of up to 19 inches), and exhaust headers with individual tubes encased in a stainless steel shell. All are unique to the 6.1-liter HEMI engine. Larger-diameter valves and reshaped ports in the heads allow for maximized air flow. The intake manifold was designed with larger-diameter and shorter runners for higher-speed tuning. Exhaust is routed through a large-diameter (2.75-inch vs. 2.5-inch) exhaust system with 4-inch chrome tips.

Power from the SRT 6.1-liter HEMI is sent through a special torque converter to an SRT-upgraded A580 five-speed automatic transmission. Torque is then sent to front and rear differentials through a specially designed transfer case.

Ride and Handling

Chassis setup is aimed at balanced performance with SRT-tuned dampers, unique sway bars and specially tailored spring rates and suspension bushings. New front suspension knuckles feature a camber angle calibrated for optimum suspension performance. The ride height of the 2006 Jeep Grand Cherokee SRT8 is one inch lower than the Jeep Grand Cherokee, which lowers aerodynamic drag and contributes to the vehicle's aggressive stance.

To meet or exceed handling and safety criteria, the Electronic Stability Program (ESP) was specially calibrated for the 2006 Jeep Grand Cherokee SRT8.
