With the new Jeep Grand Cherokee SRT8, the Jeep brand broadens its lineup and introduces a Sport Utility Vehicle that is capable of delivering outstanding driving performances in all conditions.
The new model boasts the five key SRT attributes, including awe-inspiring powertrains, functional, performance-oriented styling, world-class ride and handling, benchmark braking and race-inspired interior appointments.
The 3-cm lowered, aggressive profile of the new Jeep Grand Cherokee SRT8 reveals the unmistakable Jeep personality and unique SRT DNA. Functional design features enhance the sporty and muscular exterior of the SRT8 model: new liftgate spoiler, new split 5-spoke, 20-inch forged aluminium wheels, new wheel flares, functional dual black heat extractors on the front hood and dual-sport exhaust system.
The one-piece front fascia contains new LED multi-function daytime running lamps and 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 the new hood with functional dual black heat extractors for added engine cooling. At the rear, a unique one-piece fascia includes a separate air diffuser and offers a dual-sport exhaust system.
The 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 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 Electronic Vehicle Information Center (EVIC) controls are accessible from the horizontal spokes on the steering wheel. A power tilt and telescoping steering column is also standard.
Directly from racing technology, the standard equipment offers SRT-exclusive Performance Pages. This functionality shows 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 active front headrests, provide all the comfort for daily drives and the “grip” to keep the driver and passengers in place during spirited driving. The two front seats feature embroidered SRT logo and contrast stitching. Heated (front and rear) and ventilated (front) seats are standard.
Carbon fiber accents are integrated into the leather-wrapped instrument panel and door trim panels and new bright, racing style brake and pedal pads add to the high-performance look inside the cabin.
Jeep Grand Cherokee SRT8 is powered by the all-new 6.4-liter HEMI® V-8 with Fuel Saver Technology. New engine 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 produces 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.
Thanks to the powerful V-8 HEMI engine, new Jeep Grand Cherokee SRT8 runs from 0-100 km/h in 4.9 seconds, has a top speed of 255 km/h and brakes from 100-0 km/h in 35 m.
These astonishing performances correspond to improved fuel efficiency – a 13-percent increase on the highway thanks to the standard Fuel Saver Technology and new active valve exhaust system. Fuel Saver turns off four of the eight cylinders when full power is not required while the active valve exhaust system allows four-cylinder operation to engage over a wider rpm range for increased fuel economy.
Standard steering wheel mounted paddle shifters join the standard Auto Stick on the floor. Both are mated to a proven five-speed automatic transmission, allowing a choice of spirited shifting on the road and the race track. Both methods give the driver the ability to shift rapidly 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.
With the new Jeep Grand Cherokee SRT8, Jeep engineers have improved on-road handling even further. The best handling Jeep vehicle ever features new SRT-tuned, active Adaptive 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 according to customers’ driving habits and driving condition.
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 4×4 system can transfer up to 100 percent of available torque to one rear wheel with better grip.
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 a rear 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.
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 Brembo 6-piston (front) and 4-piston (rear) calipers, and vented rotors measuring 38 cm (front) and 35 cm (rear).
Standard equipment on the new Jeep Grand Cherokee SRT8 includes some of the most technologically advanced features available for on-board comfort, including Command-View® dual-pane sunroof, 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.
Part of the Jeep Grand Cherokee SRT8 standard equipment is a 825-watt, 19-speaker, 1 subwoofer premium audio surround-sound system from Harman Kardon®. The system offers world premier innovation, featuring a 32-volt TPS (Tracking Power Supply) 12-channel amplifier that delivers outstanding acoustics and brings multi-dimensional, quality sound for all interior occupants.
The new Jeep Grand Cherokee SRT8 offers a vast array of advanced safety and security features, including: Electronic Stability Control (ESC) with Electronic Rollover Mitigation (ERM); Brake Traction Control System (BTCS); Hill-start Assist (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); Park Assist with front and rear sensors and ParkView® rear back-up camera; High-intensity discharge (HID) Bi-Xenon headlamps with SmartBeam® system (adjusts to ambient light and oncoming traffic to deliver maximum lighting); advanced multi-stage air bags and full-length side-curtain air bags; side air bags and driver’s knee air bag; active head restraints; 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); and Adaptive Cruise Control (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.)
Additional safety and security for driver and passengers are granted by innovative systems such as Forward Collision Warning (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); Blind Spot Detection (system 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) with Rear Cross-path detection (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);
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); and 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).
