The 2013 Jeep Grand Cherokee SRT8 is the most powerful, technologically advanced, high-performance Jeep vehicle ever. The 2013 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 160 mph, and brakes from 60-0 mph in 116 feet. Powering the 2013 Jeep Grand Cherokee SRT8 is the 6.4-liter HEMI V8 with Fuel Saver Technology that delivers 470 horsepower (351 kW) and 465 lb.-ft. (630 N•m) of torque. An active intake manifold and high-lift camshaft with cam phasing delivers maximum low-end torque while optimizing high-end power across a wide rpm band. Specifically, 90-percent of peak torque is available between 2800 and 6000rpm, allowing for inspired standing starts and improved straight-line performance.
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 racetrack. 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.
The 2013 Grand Cherokee SRT8 features a SRT-tuned, adaptive damping suspension managed by the 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, Sport, Track, Snow and Tow.
The standard Jeep Quadra-Trac SRT 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 Grand Cherokee SRT8 also features an Electronic Limited Slip Differential, which eliminates rear wheel slip and improves handling.
Stopping power for the 2013 Grand Cherokee SRT8 comes courtesy of 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 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).
