"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.
Awe-inspiring powertrain
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:
• 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.
Outstanding braking
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
The 2012 Jeep Grand Cherokee's refined, luxurious interior takes on a performance feel in SRT8 form with race-inspired technology and SRT-exclusive appointments.
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.
Connectivity and Infotainment
New for 2012 is the available 825-watt, 19-speaker premium SRT performance audio surround-sound system from Harman Kardon® that includes a 10-inch subwoofer for the ultimate in sound quality.
A wide variety of easy-to-use infotainment options are available with features that provide customers with seamless integration of consumer electronics, delivering drivers and passengers the conveniences of home and office.
Garmin Navigation and SIRIUS Travel Link are standard with the 430N AM/FM/CD/DVD radio. Also standard are a multitude of features including SIRIUS Satellite Radio and Uconnect Phone.
The available Vehicle Entertainment System (VES) includes a DVD player and rear seat overhead screen that deliver a variety of programming choices, with ports to connect games and media players with audio and video output capability, including iPod® connectivity. The Media Center or the VES remote can control multiple screen inputs and each screen can play something different.

Yeah me too, either it's much heavier than the old one (some of those got into the 12s bone stock) or maybe they're just being conservative with the numbers as some manufacturers tend to be.
I like it a lot, inside and out.

HAHA, that's a joke right? The last model with less power (and more than likely, less weight) was rated for 12/16mpg. Hell, the Challenger with the same engine is rated less than that (14/22). Dodge hasn't been doing much right lately, they really need to get on the ball and start making cars people want to buy. Ford has been doing a GREAT job at this, GM is starting to, while Dodge hasn't been doing anything it seems.
