Jeep Grand Cherokee SRT8 wheel drive Jeep and versatility to a new level of excellence to offer to fans of extreme sports driving performance both on road and track. The new high-performance SRT8 version expands the Grand Cherokee and will help to attract new customers into showrooms Jeep " Manley added.
Designed using the proven formula SRT, the new Jeep Grand Cherokee SRT8's performance ensures absolute reference: it is, in fact, able to accelerate from 0-100 km / h in 4.8 seconds to go from 0-162-0 in less of 16 seconds and reach a top speed of 255 km / h. The stopping distance from 100 to 0 km / h is 35 meters. Besides the exclusive SRT8 styling details, the equipment of the new high-performance version offers the latest technological features, including the double sunroof CommandView ®, satellite navigation and entertainment system, UConnect GPS, Adaptive Cruise Control, the device with Blind Spot Monitoring Rear Cross-path detection and active suspension with shock absorbers.
A team of powerplant
The new Jeep Grand Cherokee SRT8 is equipped with the new HEMI ® V8 6.4-liter-equipped Chrysler Group Fuel Saver. The new engine has an output estimated at 470 hp (351 kw) and torque of 630 Nm: this corresponds to 50 hp and 61 Nm of torque more than the previous 6.1-liter HEMI V8 engine. An active intake manifold and a camshaft with higher lift the profile of cam timing ensures the delivery of peak torque at low engine speeds and optimizes power at high engine speeds thanks to an improved system of rotation. Specifically, 90% of peak torque is available between 2,800 and 6,000 rev / min starting from rest to ensure a true sports car on the straight and improved performance. Thanks to Fuel Saver, fitted as standard, which turns off four of the eight cylinders when full power is not required, and the new system with active exhaust valve actuation, the operation is extended to four cylinders at a speed r / min to ensure a greater reduction in consumption - estimated 13% of the motorway in the cycle - and a range of about 720 km on a single tank.
The new gear lever on the steering wheel adds to that dell'AutoStick placed on the center tunnel. Both solutions are available as standard in combination with the proven automatic transmission that permits gear changes, sport both on the road and track. The two options exchange to ensure smooth driver change. The transmission controller calibration prevents the engine revving to go. The adaptive electronic control improves engine response, reducing the stiffness.
Outstanding performance ride and handling
thanks to the new frame structure, the new Jeep Grand Cherokee offers a stylish comfort on the road. The torsional rigidity of the new shell has been increased by 146% over the previous model allowing to improve the driving dynamics and strength and reduce noise and vibration at the same time. Improvements have been made through the application of more than 5,400 spot welds in the body and increase only 53% of spot welds, 42% of the welding arc and 38% in the use of structural adhesives. With the new version SRT8, Jeep engineers have further improved the characteristics of the road in terms of handling of the Jeep Grand Cherokee. The Jeep vehicle ever more manageable - capable of recording up to 0.90 g lateral acceleration on the skid pad - has new suspension calibration with SRT administered through the new active suspension system, traction control Selec-Track.
The Selec-Track system coordinates different parameters of the vehicle (stability control, active suspension, the strategy of engagement, torque transfer to the transfer case, Electronic Limited Slip Differential, accelerator pedal and cylinder deactivation system) to automatically manage the vehicle dynamics and adapt to your driving style and road conditions. The driver can manually select from five modes of driving the most suitable to deal with driving on a particular area:
- Auto: ensure in any kind of situation, the most appropriate mode of travel. Automatically adjusts to any road surface thanks to the work of active suspensions
- Sports: ensures maximum control of the car for a sporty driving experience and 'fun' on the road
- Tow-reduces pitch and roll movements to increase the capacity Towing
- Track: provides for an adjustment 'racing' suspension to ensure high performance and ensure maximum stability and exceptional handling
- Snow: adopts the more traditional modes of driving for maximum control of vehicle dynamics in extreme weather conditions
The all-wheel drive, Quadra-Trac is standard on SRT8 Jeep Grand Cherokee. Quadra-Trac traction system is an 'on demand' which, thanks to a series of sensors, immediately notify the slippage of a wheel and sends the information to provide the necessary corrective action. The system uses the device Throttle Anticipate, which in case of sudden acceleration from a standing maximizes traction in order to avoid loss of adhesion. When the system senses slippage of a wheel, come to transfer up to 100% of torque to the wheel of the rear axle with more grip.
The transfer case improves the handling of the car because it distributes torque between front and rear axle and helps to maintain the direction set by the driver. The new Jeep Grand Cherokee SRT8 is also equipped with electronic limited slip differential limited slip ELSD (Electronic Limited-Slip Differential), which instantly detects when one rear wheel loses traction and intervenes by distributing torque to the wheel in improving the handling of the car taken .
Hydraulic steering and sport-calibrated pump is equipped with a new high-strength and a new cooling system pump. The development of the gearbox gives the driver a feeling of greater control of the car and a more immediate response. The SRT8 version of the flagship Jeep is equipped with new alloy wheels with 20 inch 5-spoke. The towing capacity is equal to 2,270 kg. Outstanding braking performance in vehicles made by Chrysler Group SRT are designed to provide exceptional stopping power. Jeep Grand Cherokee SRT8 is equipped with Brembo brakes SRT high-performance four-wheel ABS system. The stopping distance from 100 to 0 km / h is 35 meters and is the result of the adoption of new 6-piston Brembo calipers (front) and 4-piston (rear) red and ventilated discs from 38 cm ( front) and 35 cm (rear) to the four corners.
