Across Europe, the 2012 Jeep Grand Cherokee SRT8 will be available in one single specification. On top of the unique SRT8 items, standard equipment will offer some of the most technologically advanced features available today, including: Command-View® dual-pane sunroof, Uconnect satellite navigation system, adaptive cruise control, blind-spot monitoring with Rear Cross-path detection and active damping suspension.
Powering the new Jeep Grand Cherokee SRT8 is Chrysler Group’s all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology that delivers 470 horsepower (351 kW) and 630 Nm of torque – an improvement of 50 horsepower and 61 Nm 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 active valve exhaust system allows four-cylinder operation to engage over a wider rpm range, to deliver both improved fuel efficiency – a 13-percent increase on the highway – and an extended range of 720 km on one tank of gas.
Standard steering wheel mounted paddle shifters join the standard Auto Stick 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 Jeep Grand Cherokee SRT8, Jeep engineers have improved on-road handling even further. The best handling Jeep vehicle ever – capable of .90 g on the skid pad – features a new SRT-tuned, active damping suspension managed by the new Jeep Selec-Track system. This system interacts with several different systems (stability control, active 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 active 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
Quadra-Trac active on-demand four-wheel-drive transfer case is standard on the Jeep Grand Cherokee SRT8 model. This 4×4 system 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, which 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.
Jeep Grand Cherokee SRT8 features new split 5-spoke, 20-inch forged aluminum wheels.
Rounding out the capability of the new Jeep Grand Cherokee SRT8 is a trailer tow rating of 2,270 kg.
Chrysler Group’s SRT vehicles are well known for their world-class braking. Stopping power for the new Jeep Grand Cherokee SRT8 comes courtesy of new SRT high-performance Brembo brakes with four-wheel anti-lock brake system (ABS).
Stopping distance performance of 35 meters from 100-0 km/h is made possible by new red-painted, Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors at all four corners measuring 38 cm (front) and 35 cm (rear).
Sporty and functional exterior
The lowered, aggressive profile of the new Jeep Grand Cherokee SRT8 reveals the unmistakable Jeep personality and unique SRT DNA. The functional performance exterior features the “planted” look of a high-performance sports car by being lowered 3 cm 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. The new Jeep Grand Cherokee SRT8 offers a dual-sport exhaust system featuring 10 cm exhaust tips.
Race-inspired and high-performance interior
The new Jeep Grand Cherokee’s refined, exclusive 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 satin chrome 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 Grand Cherokee lineup and show instant feedback on steering input measurements, horsepower, torque, 0-100 km/h time, 100-0 km/h braking distance, g-forces, and covered distance 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.
The Command View® 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 interior cabin is further enhanced by premium leather-wrapped door trim panels, center console and instrument panel.
Safety and security
As part of the standard equipment, the new Jeep Grand Cherokee SRT8 offers a vast array of safety and security features, including:
- Active head restraints: Deploy in the event of a rear collision. Restraints are designed to reduce injuries by minimizing the gap between the head restraint and the passenger’s head;
- Adaptive cruise control (ACC): The system decreases the vehicle’s pre-set cruise-control speed when closing in on another vehicle in the same lane, or when another vehicle pulls into the same lane. The system will accelerate to the pre-set speed when the vehicle in front speeds up or moves into another lane. ACC will maintain a driver adjustable distance between the vehicle and the one in front of it, allowing the use of cruise control in light traffic without having to continuously adjust settings;
- Advanced multi-stage air bags: Inflates with a force appropriate to the severity of the impact for smaller, out-of-position occupants;
- Blind-spot Monitoring (BSM): Uses dual ultra-wideband radar sensors to aid the driver when changing lanes, or if being passed by or passing unseen vehicles. The system notifies the driver of vehicle(s) in their blind spot via illuminated icons on the sideview mirror and with a driver-selected audible chime;
- Brake-traction control system (BTCS): Helps to keep driving wheels from spinning
during acceleration from a stop or during slow speeds by applying individual brakes to the slipping wheel(s);
- Electronic roll mitigation (ERM): An extension of electronic stability control (ESC). Uses input from ESC sensors to anticipate if the vehicle is at risk of entering a potential roll situation, then applies the brakes individually and modulates the throttle position as needed;
- Electronic stability control (ESC): Enhances driver control and helps maintain directional stability under all conditions. Provides the benefit in critical driving situations such as turns, and is valuable when driving on mixed surface conditions including snow, ice or gravel. If there is a discernible difference between driver input through the steering wheel and the vehicle’s path, ESC applies selective braking and throttle input to guide the vehicle back on to the driver’s intended path;
- Energy-absorbing steering column: The power-adjust steering column employs a calibrated bending element that deforms during column stroke for optimal energy management;
- Enhanced Accident Response System (EARS): Makes it easier for emergency personnel to see and reach occupants in the event of an accident by turning on the interior lighting and unlocking doors after air bag deployment. Also shuts off flow of fuel to the engine;
- Forward Collision Warning (FCW): Using forward-facing radar sensors, this system detects when the vehicle may be approaching another vehicle too rapidly and alerts the driver so the driver can determine what action must be taken in order to prevent the vehicle from a collision;
- High-intensity discharge (HID) Bi-Xenon headlamps: Provide approximately three times the light output of conventional reflector lamps for improved nighttime illumination;
- Hill-start Assist (HSA): Assists drivers when starting a vehicle from a stop on a hill by maintaining the level of brake pressure applied for a short period of time after a driver’s foot is removed from the brake pedal. If throttle is not applied within a short period of time after the driver’s foot is removed from the brake pedal, brake pressure will be released;
- Keyless Enter-N-Go: When an individual enters the vehicle, electronic sensors detect if the vehicle key fob is present. The vehicle will then allow the individual to push a button to start the vehicle without having to insert the key into the ignition;
- ParkSense® rear park assist system: Assists at low speeds in reverse to detect stationary objects. Consists of audible warnings for the driver and has a display in the Electronic Vehicle Information Center (EVIC) integrated into the instrument cluster;
- ParkView® rear back-up camera: Provides a wide-angle view of the area immediately behind the vehicle, giving the driver greater peace of mind before reversing at low speeds. Contains grid line to aid the driver when maneuvering into parking spaces or narrow areas. Also aids in lining up a trailer to the vehicle’s trailer hitch, when so equipped. The image is displayed on the navigation screen when the transmission is shifted into Reverse;
- Power tilt-and-telescoping steering column with memory: Allows steering column to tilt and move toward or away from the driver to achieve a safe and comfortable distance from the advanced multi-stage front driver air bag, if deployed;
- Rain Brake Support: Uses the ESC pump to occasionally push brake pads lightly against brake rotors in rainy conditions in order to keep rotors dry;
- Ready Alert Braking: Anticipates situations when the driver may initiate an emergency brake stop and uses the ESC pump to set brake pads against rotors in order to decrease the time required for full brake application;
- Rear Cross Path (RCP): In parking lot situations, this system warns drivers backing out of parking spaces of traffic moving toward their vehicle. It activates any time the vehicle is in Reverse. The driver is notified of vehicle(s) crossing behind the vehicle via illuminated icons on the sideview mirror and with a driver-selected audible chime;
- SmartBeam® headlamps: Headlamp system adjusts to ambient light and oncoming traffic to deliver maximum lighting;
- Standard full-length side-curtain air bags: Extend protection to all outboard front- and rear-seat passengers. Each side air bag has its own impact sensor that autonomously triggers the air bag on the side where an impact occurs. This type of air bag is housed in the headliner just above side windows;
- Standard seat-mounted side thorax air bags: Provide enhanced protection to the
driver and front outboard passenger in certain impacts. Each side air bag has its own impact sensor that autonomously triggers the air bag on the side where an impact occurs. Standard side air bags are housed within the outboard side of each front seat;
- Trailer-sway control (TSC): Reduces trailer sway and improves handling in adverse towing conditions caused by crosswinds and traffic. The system monitors the vehicle’s movement relative to the driver’s intended path, then applies alternating brake pressure to slow the vehicle and then increases the pressure on one front wheel in order to counteract the sway induced by the trailer.
Connectivity and Infotainment
Jeep Grand Cherokee SRT8 features standard multimedia infotainment and navigation UConnect GPS system with 6.5-inches touchscreen, 30 gigabyte hard disk, USB compatibility, AUX port, DVD video and voice activated Bluethooth UConnect Phone with integrated microphone in the rearview mirror.

The system offers world premier innovation, featuring a 32-volt TPS (Tracking Power Supply) 12-channel Class D amplifier that delivers outstanding acoustics and brings multi-dimensional, quality sound for all interior occupants.
Jeep® Wrangler 3.6-liter V-6: the Pentastar engine equipped on the Jeep icon
3.6-liter V-6 powertrain provides more fuel efficiency, improved on-road driving dynamics and refinement, more power and more torque. Petrol powertrain now adds upgraded automatic transmission for refined shifting and greater performance. Dramatically improved on-road performance combines with even more off-road prowess. New petrol engine joins 2.8-liter turbo diesel engine for European lineup.
In Europe, the all-new 3.6-liter petrol powertrain will be introduced on Jeep Wrangler and Jeep Wrangler Unlimited Sport, Sahara and Rubicon trim levels starting November 2011.
At the 2011 Frankfurt Motor Show, Jeep show-cases the iconic Jeep Wrangler equipped with the all-new 3.6-liter Pentastar V-6 engine.
Jeep Wrangler – the most capable and iconic vehicle in the world – now becomes even more capable both on- and off-road, courtesy of an all-new, more fuel-efficient and more powerful 3.6-liter V-6 petrol engine and a five-speed automatic transmission – both of which it shares with the award-winning* Jeep Grand Cherokee (*for awards see appendix).
The all-new 3.6-liter Pentastar V-6 engine and automatic transmission enhance Jeep Wrangler’s on-road driving performance – delivering a 5-percent improvement in fuel consumption, 42-percent more power and 10-percent more torque – while also taking the vehicle’s legendary off-road capability to a new level.
“Jeep Wrangler – the most capable and iconic vehicle in the world – has a new heart but retains the same spiritual soul,” said Mike Manley, President and CEO – Jeep Brand and Chief Operating Officer Asia, Chrysler Group LLC. “Our new 3.6-liter V-6 engine gives the ever-capable Wrangler a completely new, more refined on-road driving experience – complete with more fuel efficiency, power and torque.
“Available in 2-door and 4-door models and boasting an untouchable combination of efficient design, open-air freedom, improved real-world drivability and unique 4×4 systems that deliver unmatched off-road prowess, Jeep Wrangler once again resets the benchmark and offers consumers the ultimate vehicle for any driving adventure,” Manley added.
Chrysler Group’s 3.6-liter Pentastar V-6 engine – named to the prestigious U.S. automotive media outlet Ward’s “10 Best Engines” list – delivers 284 horsepower DIN (209 kW) and 347 N•m (256 lb-ft) of torque, along with greater fuel efficiency over the previous 3.8-liter V-6 engine.
Additionally, for refined shifting and greater performance, Jeep Wrangler petrol models migrate from a four-speed to a five-speed automatic transmission. The newest Jeep Wrangler also features the company’s first application of a manual transmission to the Pentastar V-6.
The Jeep Wrangler and Wrangler Unlimited will continue to be available in three models for European markets: Sport, Sahara and Rubicon. Combined with an all-new interior for 2011, the newest Jeep Wrangler is virtually all-new over the past year and will excite core Jeep followers while appealing to new customers.
3.6-liter Pentastar V-6 Engine
Compact and lightweight, the all-aluminum 3.6-liter Pentastar V-6 engine is more than 40 kg (90 lbs) lighter than the previous 3.8-liter V-6 engine that was constructed with a cast-iron block. The Pentastar engine is extremely quiet, constructed with a high-pressure, die-cast aluminum block fitted with cast-iron bore liners and aluminum cylinder heads. The engine also has been designed to meet all known future worldwide emission standards and is currently Euro 5 certified.
The 3.6-liter V-6 engine is manufactured at the Trenton engine plant in Michigan (USA).
The A580 automatic transmission benefits Jeep Wrangler as much as the new petrol engine, with more refined shifting and gear selection. By increasing the number of speeds, the transmission allows the engine to operate in a more efficient RPM range, which helps increase fuel economy. More speeds also enable the engine to remain in the torque curve, increasing acceleration. The new Wrangler (two-door) boasts a 37-percent improvement in 0 – 100 km/h time, which is now 8.1 seconds. Also, a lower first-gear ratio in the new automatic transmission gives the Wrangler more off-road capability via a lower overall crawl ratio.
Electronic Range Select is standard for all automatic-equipped Jeep Wrangler models. The electronic stability control (ESC) also has been optimized to perform effortlessly with the new 3.6-liter V-6 engine.
Along with the proven NSG 370 six-speed manual transmission, engineered for the newest Jeep Wrangler are a new clutch housing, flywheel and long-travel damper clutch. The improvements are a result of the adaptation of the transmission to the 3.6-liter V-6 engine.
The five-speed automatic transmission is produced in Kokomo, Indiana (ITP2), and the six-speed manual transmission is produced in Gaggenau, Germany.
Jeep Wrangler delivers unmatched off-road capability with legendary four-wheel drive and is produced with more than seven decades of 4×4 engineering experience behind it. Wrangler continues to offer a body-on-frame design, front and rear five-link suspension system, live axles and electronic lockers.
Jeep Wrangler now offers a choice of two transmissions: a six-speed manual and a five-speed automatic gearbox.
Along with a new powertrain, Jeep engineers have thoroughly optimized ride and sound characteristics of the Jeep Wrangler’s body-on-frame design. New motor and transmission adaptations and revised suspension calibrations contribute to overall improvements that are immediately evident both on- and off-road.
The interior sound quality is greatly improved through refinements in the powertrain mounting system, noise damping in the firewall and the inclusion of the first Jeep Wrangler engine cover to effectively isolate the cabin from noises emulating from the engine and road surfaces.
On the outside, engine noise is barely perceptible at idle. With the new 3.6-liter V-6 engine, all accessories are mounted directly to the engine with no accessory brackets. This helps ensure that all accessories, including the power steering pump, alternator and air conditioning compressor, are anchored firmly and less susceptible to vibration and noise.
Shocks have also been retuned and are designed for optimum balance between advanced on-road handling and rugged off-road capability.
Axles and Transfer Cases
The Jeep Wrangler is now available with more axle gear ratios, allowing customers to optimize fuel economy and/or vehicle capability. Wrangler is available with 3.21, 3.73 or 4.10 ratios depending on model. Also, Wrangler offers towing capability up to 2,500 kg.
The capable driveline of the Sport and Sahara models includes a Dana 30 front axle and Dana 44 rear axle. The Command-Trac® NV241 part-time, two-speed transfer case features a 2.72:1 low-range gear ratio.
The Rubicon model features heavy-duty Dana 44 front and rear axles and the Rock-Trac® NV241 two-speed transfer case with a 4.0:1 low-range gear ratio. Rubicon also includes electric front and rear locking differentials and disconnecting front sway bar, taking Jeep Wrangler to the highest level of capability.
2.8-liter CRD Engine
The all-new 3.6-liter V-6 engine joins the new 2.8-liter turbo diesel engine with fuel-saving Stop/Start technology. The diesel engine provides power of 200 hp DIN (147 kW), a 13-percent improvement over the prior 2.8-liter diesel engine. Torque for the engine comes in at 410 N•m (302 lb-ft) with its six-speed manual transmission and 460 N•m (339 lb-ft) with its five-speed automatic transmission.
Jeep Wrangler’s diesel engine, when paired with the manual transmission, incorporates Stop/Start technology – the first application of this technology on a Chrysler Group vehicle. Stop/Start improves fuel efficiency and reduces CO2 emissions by managing the amount of time the engine runs. With Stop/Start, the engine is shut off when the vehicle is stopped, the shift gear is in Neutral and the clutch is released. The engine then restarts automatically when the clutch pedal is depressed. Drivers can deactivate the technology via a button on the dashboard, and an icon displays in the instrument panel to indicate the Stop/Start status.
