Jeep Grand Cherokee (WK)
The third Grand Cherokee grew in length and wheelbase and switched to independent front suspension. The long-serving 4.0 L six gave way to a 3.7 L V6, and the 5.7 L Hemi V8 with cylinder deactivation became the top engine. The 2006 SRT8 added a 6.1 L Hemi and Brembo brakes, turning the Grand Cherokee into a performance SUV, and a Mercedes-built 3.0 L diesel was sold in North America for 2007 and 2008. Wikipedia lists the Commander (XK) as a related model.
