| Predecessor | Grand Cherokee WK |
The fourth-generation Jeep Grand Cherokee (WK2) is a mid-size luxury SUV introduced in late 2010 for the 2011 model year by Jeep. It was unveiled at the 2009 New York Auto Show. The fourth-generation Grand Cherokee retains its classic Jeep styling combined with a modern and sleek body style. The interior is luxurious, featuring leather trim and real wood accents, plus state-of-the-art electronics options. The 2011 Grand Cherokee has won 30 awards for off-road capability, luxury, value, best-in-class, and safety, making it the most awarded SUV ever. Among the awards are: Top Safety Pick for 2011 from the IIHS, listed as a Consumers Digest Best Buy for 2011, Safest SUV in America by MSN Autos, and Truck of the Year for 2011 by The Detroit News.
The body design is all new and has undergone testing for aerodynamic efficiency while improving ruggedness with more than 5,400 welds in the body alone. This results in a 146% increase in torsional rigidity compared to the previous design. This improves durability and reduces noise, vibration, and harshness.
Like the previous generations, the chassis is a steel unibody. Unlike previous models, the new WK2 features four-wheel independent suspension for better on-road handling. The Grand Cherokee (with the 2011 Durango) WK2 platform uses a derivative based on Mercedes-Benz's W166 series.
Four wheel drive systems include Quadra-Trac I, Quadra-Trac II, and Quadra-Drive II. Using Selec-Terrain, the driver can select modes for Auto, Sport, Snow, Sand/Mud, and Rock.
Optional Quadra-Lift height adjustable air suspension can raise the vehicle's ground clearance up to 11.1 in (282 mm). Lift modes include Park, Aero, Normal Ride Height, Off-Road 1, and Off-Road 2.
