"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 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.
Powering the 2012 Jeep Grand Cherokee SRT8 is Chrysler Group's all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers an estimated 465 horsepower and 465 lb.-ft. of torque an improvement of 45 horsepower and 45 lb.-ft. torque over the 6.1-liter HEMI V-8 it replaces.
An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wider and improved rpm band. Specifically, 90-percent of peak torque is available between 2,800 and 6,000 rpm, allowing for inspired standing starts and improved straight-line performance.
Standard Fuel Saver Technology and a new-for-2012 active valve exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency an estimated 13-percent increase on the highway and an extended range of approximately 450 miles on one tank of gas.
Standard steering wheel mounted paddle shifters join the standard AutoStick on the floor. Both are mated to a proven automatic transmission, allowing a choice of spirited shifting on the road and the race track. Both methods give the driver the ability to shift while the transmission controller calibration prevents situations that might over rev the engine. Fully adaptive electronic control of all shifting makes the powertrain more responsive while minimizing harshness.
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:
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.
At the rear, the SRT performance influence continues with a new liftgate spoiler that reduces drag and improves downforce. A unique one-piece rear fascia includes a separate air diffuser along with an available trailer receiver and access cover. New for the 2012 version of the Grand Cherokee SRT8 is the dual-sport exhaust system featuring 4-inch exhaust tips.
Race-inspired and functional interior
An all-new, leather-wrapped, heated steering wheel features a unique rim section with a flattened bottom surface evoking a race-inspired cockpit that showcases the SRT logo. Standard paddle-shift controls flank both sides of the new contoured palm rests while all audio and Electronic Vehicle Information Center (EVIC) controls are accessible from the horizontal spokes on the steering wheel. A power tilt and telescoping steering column also is standard.
SRT-exclusive Performance Pages are new for 2012 and show instant feedback on steering input measurements, horsepower, torque, 0-60 mph time, 60-0 mph braking distance, g-forces, and one-eighth mile and quarter-mile times, along with expanded engine information.
New SRT-styled Nappa leather and suede seats, with sculpted bolsters and adjustable headrests, provide all the comfort for daily drives and "grip" to keep the driver and passengers in place during spirited driving. The embroidered SRT logos and contrast stitching accent the two front seats. Heated (front and rear) and ventilated (front) seats are standard.
Carbon fiber accents are integrated into the instrument panel and door trim panels and new bright, racing style brake and pedal pads add to the high-performance look inside the cabin.
An available CommandView® dual-pane sun roof provides twice as much glass surface than a standard sun roof and extends from the windshield to the rear of the vehicle.
The available Luxury Group package adds premium leather to the door trim panels, instrument panel and center console along with a power liftgate, adaptive cruise control, Forward Collision Warning and Blind-spot Monitoring.
