Standard Launch Control optimizes the Grand Cherokee Trackhawk’s performance by coordinating the engine, transmission, driveline and suspension for a textbook launch and consistent straight-line acceleration.

A new standard Torque Reserve system provides improved engine torque response and quicker vehicle acceleration in Launch Control by pre-positioning the supercharger bypass valve to generate boost and minimize manifold filling time, while cutting fueling to individual cylinders and managing spark timing. This generates a reserve of torque that can be instantaneously delivered upon acceleration from a standing stop.

The new benchmark 707-horsepower supercharged engine combines with an upgraded high-torque capacity TorqueFlite eight-speed automatic transmission, world-class on-road driving dynamics and new Brembo brakes to deliver a new level of performance: 0-60 miles per hour (mph) in 3.5 seconds, quarter mile in 11.6 seconds at 116 mph, top speed of 180 mph, 60-0 mph braking distance in 114 feet and .88 g capability on the skid pad.
