All New 2012 Jeep Grand Cherokee SRT8
The most powerful, technologically advanced, high-performance Jeep vehicle ever with a combination of Jeep's legendary capability and utility, merged with the renowned advanced performance engineering from Chrysler Group LLC's Street and Racing Technology (SRT) team.
Delivering outstanding driving performance in all conditions, and complemented by key SRT attributes - including functional, performance-oriented styling, world-class ride and handling, benchmark braking and race-inspired interior appointments - the 2012 Jeep Grand Cherokee SRT8 broadens the Jeep vehicle lineup and builds upon the successful launch of the award-winning 2011 Jeep Grand Cherokee.
"The all-new 2012 Grand Cherokee SRT8 is the ultimate performance SUV, delivering a combination of Jeep capability and utility, world-class performance, luxury and refinement, and advanced innovative technology," said Mike Manley, President and CEO — Jeep Brand, Chrysler Group LLC. "Jeep vehicles have long been known for their off-road capability. In addition to Jeep four-wheel-drive traction and utility, the Jeep Grand Cherokee SRT8 takes capability to a new level by giving driving enthusiasts extreme performance for the street and track.
"Our new benchmark performance SUV effectively broadens the Grand Cherokee portfolio, and will continue to draw new customers into Jeep showrooms," Manley added.
Designed and built using the proven SRT formula that raises the performance to astonishing levels, the new 2012 Jeep Grand Cherokee SRT8 runs from 0-60 mph in 4.8 seconds, 0-100-0 mph in the mid-16 second range, can cover the quarter mile in the mid-13 second range, has a top speed of 155 mph, and brakes from 60-0 mph in 116 feet.
Owners of any Chrysler Group SRT vehicle receive one day of professional driving instruction from the Richard Petty Racing School as part of the SRT Track Experience, designed to maximize their driving knowledge and skills on the street or track. Sessions are held throughout the year at selected tracks.
Outstanding ride, handling and capability:
For 2011, all Jeep Grand Cherokee models boast an improved and refined on-road ride thanks in part to the vehicle's body structure. Torsional stiffness was improved 146 percent versus the previous model, for improved ride, durability and reduced noise, vibration and harshness. The improvement is achieved with more than 5,400 welds in the body alone, marking a 53-percent increase in spot welds, a 42-percent increase in arc welds and a 38-percent increase in structural adhesive.
With the new 2012 Grand Cherokee SRT8, engineers have improved handling even further.
The best handling Jeep vehicle ever - capable of .90 g on the skid pad - features a new SRT-tuned, adaptive damping suspension managed by the new Jeep Selec-Track system that interacts with several different systems (stability control, adaptive damping, transmission shift strategy, transfer case torque proportioning, Electronic Limited Slip Differential performance, throttle control and cylinder de-activation) to automatically tune the dynamics of the vehicle. Drivers can manually choose between five dynamic modes for specific driving conditions:
Auto: provides the most compliant ride and automatically adapts to any road situation using the adaptive suspension tuning
Sport: provides enhanced body control for a sporty, fun-to-drive ride for the street
Tow: provides a safe reduction in pitch and bounce for enhanced towing capability
Track: provides the high-performance, firm, "track-tuned" suspension option to lock down body motion for the ultimate handling experience
Snow: provides the most conservative dynamic mode, so the vehicle will safely stay in-line in inclement winter weather conditions
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 4x4 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.
