Jeep has taken the 707 hp engine from the Hellcat and stuffed it into the Grand Cherokee to create the very fast and capable Grand Cherokee Trackhawk. The rear drive shaft, rear axle and other driveline components have been strengthened to keep up with the extra torque of the engine whilst retaining reliability. The TorqueFlite eight-speed automatic transmission has been tweaked to improve shift response, quality and consistent performance and drivability on the road and track.
"Long recognized as the full-size SUV capability leader, Jeep Grand Cherokee is now the most powerful and quickest SUV as well, with the introduction of our new 707-horsepower Trackhawk," said Mike Manley, Head of Jeep Brand - FCA Global. "The new Grand Cherokee Trackhawk delivers astounding performance numbers, backed by renowned SRT engineering that combines world-class on-road driving dynamics with luxury, refinement and an array of innovative advanced technology."
