The standard Jeep Quadra-Trac active on-demand four-wheel-drive transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire slippage is detected, the Jeep 4×4 system can transfer up to 100 percent of available torque to one rear wheel.
The transfer case also enhances handling by proportioning torque between the front and rear axles to maintain the driver’s intended path. The new Grand Cherokee SRT8 also features an Electronic Limited Slip Differential that eliminates rear wheel slip and improves handling.
The performance-tuned, fully-hydraulic steering system is improved with a new, heavy-duty pump and pump cooler. Revised gearing gives drivers more direct feel and on-center response.
New split 5-spoke, 20-inch forged aluminum wheels ride on P295/45ZR20 Pirelli PZero run-flat tires (standard All-season or available Three-season).
Rounding out the capability of the 2012 Jeep Grand Cherokee SRT8 is a trailer tow rating of 5,000 lbs.
Chrysler Group’s SRT vehicles are well known for their world-class braking. Stopping power for the 2012 Grand Cherokee SRT8 comes courtesy of new SRT high-performance Brembo brakes with four-wheel anti-lock brake system (ABS).
Stopping distance performance of 116 feet from 60-0 mph is made possible by new red-painted, Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 15-inches (front) and 13.8-inches (rear).
Aggressive and functional exterior
The functional performance exterior of the 2012 Grand Cherokee SRT8 features the “planted” look of a high-performance sports car by being lowered 1 inch and adding new, SRT-exclusive, body-color wheel flares and side sill cladding.
A one-piece front fascia contains new LED multi-function daytime running lamps that result in an exclusive face for the new Jeep Grand Cherokee SRT8, while a body-colored front grille with a unique black screen background and chrome bezel inserts adds to the aggressive look.
The integrated lower front grille is painted in gloss black and a newly designed underbody belly pan features integrated brake ducting to improve cooling and fade performance. Completing the new front end is a newly sculpted hood with functional dual black heat extractors for added engine cooling.
