Jeep Grand Cherokee SRT8

The all-new WK Grand Cherokee debuted in 2004 for the 2005 model year. Features available for the first time in a Jeep included Quadra-Drive II four wheel drive and a rear-seat DVD player.

The design still emphasizes power and luxury, with significant work done on improving noise, vibration, and harshness (NVH). However, for the first time, Jeep also emphasized on-road performance to a similar extent as the cornerstone of its brand, off-road capability.

This newfound emphasis on on-road refinement led Jeep to replace the live-axle with leading-arms front suspension found in the ZJ and WJ, prized by off-roading Jeep fans for its ability to maintain consistent ground clearance and provide optimal wheel articulation, with a double-wishbone independent setup like that which debuted in the 2002 Liberty. Jeep changed its philosophy due to what it perceived as increasing demand in the SUV marketplace for on-road performance and decreasing demand for off-road capability.
