The all-new third generation Grand Cherokee (WK) was unveiled at the 2004 New York International Auto Show by Jeepfor the 2005 model year. New features for Jeep included, Quadra-Drive II four-wheel drive, rear-seat DVD player, and optional 5.7 L Hemi V8 engine. The 3.7 L V6 engine replaced the 4.0 L Straight-6 engine.
The design still emphasized power and luxury, with significant work done on reducing 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.
