The fourth-generation Jeep Grand Cherokee went on sale in summer 2010 as a 2011 model. It was unveiled at the 2009 New York Auto Show. During development of the WK2 Grand Cherokee, it was used as one of the examples of future products by Chrysler management at the time to convince United States federal regulators in 2009 of Chrysler’s future viability in requesting a federal loan, which culminated in the Chrysler Chapter 11 reorganization that same year.
The fourth-generation Grand Cherokee retains its classic Jeep styling combined with a modern and sleek body style. The interior features leather trim and real wood accents, plus Bluetooth and uConnect 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.
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 Chrysler designed and engineered platform/chassis that Mercedes-Benz later used for the Mercedes-Benz’s W166 series. The Chrysler-designed platform/chassis was part of the DaimerChrysler engineering projects that was to launch the new Grand Cherokee with the Mercedes-Benz ML to follow. However, due to the subsequent sale and bankruptcy of Chrysler, the Grand Cherokee launch was delayed and the Mercedes ML launched before the WK2 Grand Cherokee.
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.
Engine choices include the all new 3.6 L Pentastar V6 and 5.7 L Hemi V8. The Hemi V8 retains the Multiple Displacement System (MDS) that shuts down four cylinders in low-power driving situations. The V8 comes with the multi-speed automatic transmission that includes Electronic Range Selection (ERS) to manually limit the high gear operating range. Trailer towing is rated 7,400 lb (3,400 kg) for Hemi models and 5,000 lb (2,300 kg) for Pentastar models. A 3.0 L turbocharged diesel V6 developed and built by Fiat Powertrain Technologies and VM Motori (with Multijet II injection) rated at 177 kW (241 PS; 237 hp) and 550 N·m (410 lb·ft) of torque offered in export markets from mid-2011. The new 3.0 L CRD turbodiesel engine is available in European markets as 140 kW (190 PS; 188 hp) low-power version.
The new Grand Cherokee SRT8, which started production on July 16, 2011, is equipped with a 470 hp (350 kW; 480 PS) 6.4 L Hemi V8 engine. Jeep claims the new SRT8 gets 13 percent better fuel economy than its predecessor. To keep the gas mileage respectable,[clarification needed] Jeep has employed a new active exhaust system that lets Chrysler’s cylinder-deactivating Fuel Saver Technology operate over a wider rpm band. Chrysler claims that with the larger gas tank, the SUV can now travel up to 500 miles (800 km) on a single tank, while other sources estimate range to be 450 miles (720 km).
The Jeep Grand Cherokee was released in India on 30 August 2016. Along side the Wrangler, the Grand Cherokee was the first model to be sold directly by Jeep in the country. Jeeps have been built under licence by Mahindra in India since the 1960s.
