Nearly 18 years ago, Jeep claims to have invented the premium SUV segment with the introduction of the Jeep Grand Cherokee. To date, the Grand Cherokee remains one of the few bright spots in Chrysler’s otherwise embarrassing line-up of underpowered, outdated or mediocre vehicles. The 2011 Jeep Grand Cherokee was unveiled at the 2009 New York Auto Show, and it looks ready to take on the world, assuming Chrysler survives.

The all-new Jeep Grand Cherokee delivers premium on-road performance while maintaining the Jeep brand’s legendary four-wheel-drive, torque-on-demand two-speed transfer case and towing capability. It also offers improved fuel economy (up to
11 percent) and a world-class interior cabin.

The all-new Quadra-Lift air suspension system delivers legendary Jeep off-road capability along with the new Selec-Terrain system that allows the driver to choose the drive system that best matches on- or off-road driving conditions. New front and rear independent suspension systems deliver premium on-road handling and comfort.

The all-new 2011 Jeep Grand Cherokee is built on a proven rear-wheel-drive unibody platform sharing the same underpinnings as the Mercedes-Benz ML.

The all-new Jeep Grand Cherokee offers the new Quadra-Lift air suspension system. Quadra-Lift adds up to 4.5 inches of lift span that is supported by four-corner air springs that provide a cushioned, premium ride. Quadra-Lift operates automatically, or may be controlled manually via console controls.

In addition to the Quadra-Lift air suspension, the all-new Selec-Terrain traction control system lets customers choose the off-road setting for the optimum experience on all terrains. This feature electronically coordinates up to 12 different powertrain, braking and suspension systems, including throttle control, transmission shift, transfer case, Traction Control and Electronic Stability Control (ESC).

With the front air dam removed, and the available Quadra-Lift air suspension, the all-new Jeep Grand Cherokee features a 35.9-degree approach angle, (compared to 32.3 on current model), a 29.2-degree departure angle (compared to 27.5 on current model) and 25.1-degree breakover angle (compared to 20.4 on current model).

The all-new independent front and rear suspension features isolated front and rear suspension cradles. Variable-rate rear springs deliver improved on-road handling and comfort that complements the vehicle’s off-road capability. The new rear suspension allows the spare tire to be stored inside the vehicle as opposed to underneath.

All 2011 Jeep Grand Cherokees equipped with either the off-road or the Quadra-Lift group are Trail Rated®. The Jeep Trail Rated badge on the 2011 Jeep Grand Cherokee indicates that the vehicle has been designed to perform in a variety of challenging off-road conditions identified by five key consumer-oriented performance categories: traction, ground clearance, maneuverability, articulation and water fording.

The 2011 Jeep Grand Cherokee’s standard engine is an all-new flexible fuel 3.6L V6 engine. The 3.6L V6 engine is an all-new design featuring double overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration. It features Variable-Valve Timing (VVT) and delivers 280 hp and 260 lb-ft of torque at 4,800 rpm. This all-new V6 engine improves fuel economy up to 11 percent compared to the previous Grand Cherokee equipped with a V6. It is coupled with the proven W5A580, a five-speed automatic transmission that delivers smooth shifts and optimum fuel economy. The five-speed W5A580 transmission includes adaptive electronic control or Electronic Range Select (ERS) driver-interactive manual control and an electronically modulated torque converter clutch.

The available legendary 5.7L HEMI V8 engine delivers 360 hp and 390 lb-ft of torque at 4,250 rpm. The HEMI also features VVT, which delivers performance and towing capability, as well as fuel efficiency with the fuel-saving Multi-displacement System (MDS). The 5.7L HEMI V8 engine is mated to the 545RFE multi-speed automatic transmission.

The all-new Jeep Grand Cherokee offers unsurpassed trailer tow capability of up to 7,400 lbs. on 4×2 models when equipped with the HEMI V8 engine.

The all-new interior is elevated to that of its European competition and features rich materials and elegant appointments, as well as more room for both passengers and cargo.

An available all-new CommandView dual-pane sun roof provides twice as much glass surface than a standard sun roof and extends from the windshield to the rear of the vehicle. The front panel can be opened rearward, providing additional light and fresh air to first-row passengers. The rear panel, which is fixed, allows light and open viewing for second-row passengers and comes standard with a power sun shade.

The vehicle’s 114.8-inch wheelbase is 5.3 inches longer than the model it replaces and contributes to an overall vehicle length that is 1.8 inches longer than the prior model. The longer wheelbase creates more interior room and gives passengers an additional 4 inches of rear-seat knee and leg room. The vehicle also is 3 inches wider for improved handling and packaging.

Standard safety features include Electronic Stability Control (ESC), Electronic Roll Mitigation (ERM), four-wheel Anti-lock Brake System (ABS) with rough-road detection, four-wheel Brake Traction Control System (BTCS), Passive Entry/Keyless Go, Remote keyless entry, express up/down windows for driver and front-seat passenger, seat-belt pretensioners, Trailer-Sway Control and Remote-Start which is standard on Overland and available on Limited.

Other standard safety features include full-length side-curtain air bags which extend protection to front and rear outboard passengers, seat-mounted side thorax air bags that enhance protection for the driver and front passenger and active head restraints which deploy in the event of a rear collision.

The all-new 2011 Jeep Grand Cherokee will feature uconnect guardian as a standard feature on all models (services provided by Hughes Telematics).

In preparation for production of the all-new Grand Cherokee, Jefferson North Assembly is undergoing a 285,000-square-foot expansion to replace the existing body shop, which is part of Chrysler’s investment of approximately $1.8 billion in new vehicle programs. In addition, changes throughout paint and assembly operations will give the facility an all-new level of manufacturing flexibility for multiple product capability.
