Nearly two decades ago, Jeep invented the premium sport-utility vehicle (SUV) segment with the introduction of the Jeep Grand Cherokee. More than 4 million sales later, Jeep improves the formula and hits the sweet spot of Jeep 4x4 capability and on-road refinement with the all-new 2011 Jeep Grand Cherokee.
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 23 mpg) and a world-class interior cabin.
The all-new Quadra-Lift(TM) air suspension system delivers legendary Jeep off-road capability along with the new Selec-Terrain(TM) 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.
"With the all-new 2011 Grand Cherokee, Jeep has created the benchmark, premium SUV," said Mike Manley, President and Chief Executive Officer -- Jeep Brand, Chrysler Group LLC. "Unique innovations such as our new Quadra-Lift air suspension system and Selec-Terrain traction control systems separate Jeep from the crowd and take the new Grand Cherokee to the next level of 4x4 capability. The new generation of the iconic Jeep Grand Cherokee delivers the perfect blend of on-road refinement, superb craftsmanship, world-class design, improved fuel economy, innovative features and legendary, real-world capability."
The all-new Jeep Grand Cherokee offers the new Quadra-Lift air suspension system.
The Quadra-Lift air suspension system features five height settings for optimum ride performance:
-- Normal Ride Height (NRH): 8.1 inches of clearance offers improved fuel economy and improved aerodynamics during on-road driving -- Off-road 1: Lifts the vehicle an additional 1.3 inches for added height in clearing obstacles (9.4 inches) -- Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 2.6 inches of height for 10.7 inches of ground clearance -- Park Mode: Lowers the vehicle 1.5 inches from NRH for easy ingress/egress and roof rack loading. NRH and Park mode are driver-selectable, giving the driver control over vehicle ride height -- Aero Mode: Lowers the vehicle .6 inches from NRH. Aero mode is controlled by vehicle speed and adjusts for optimal performance and fuel economy
Quadra-Lift adds up to 4.1 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 system, 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).
The Selec-Terrain's control dial allows the driver to choose from five driving conditions in order to achieve the best driving experience on all terrains:
-- Sand/Mud: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque is tuned for optimal performance -- Sport: Provides enhanced on-road "fun-to-drive" capability -- Auto: Automatically adapts to any on- or off-road situation -- Snow: Vehicle traction adjusts for ultimate performance over snow-covered roads -- Rock: Quadra-Lift air suspension system raises to maximum height (10.7 inches) and the transfer case, differentials, and throttle coordinate to provide low-speed control
Selec-Terrain, coupled with the all-new Quadra-Lift air suspension system, offers drivers an adjustable suspension span that delivers world-class capability.
With the front air dam removed, and the available Quadra-Lift air suspension system, the all-new Jeep Grand Cherokee features a 34.3-degree approach angle, (compared to 32.3 on previous model), a 29.3-degree departure angle (compared to 27.5 on previous model) and 23.1-degree breakover angle (compared to 20.4 on previous model).
The all-new front and rear independent 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.
Go-Anywhere 4x4 Systems
The 2011 Jeep Grand Cherokee offers three 4x4 systems (Quadra-Trac I®, Quadra-Trac II® and Quadra-Drive® II).
Quadra-Trac I delivers full-time four-wheel drive without any switches or levers to pull.
The system provides smooth operation over a variety of road conditions. This light-weight single-speed case is both proven and highly efficient for enhanced fuel economy.
Quadra-Trac II's two-speed transfer case uses input from a variety of sensors in order to determine tire slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before slippage occurs. When tire slippage is detected, as much as 100 percent of available torque is instantly routed to the axle with the most traction.
Quadra-Drive II, with a rear Electronic Limited-slip Differential (ELSD), delivers industry-leading tractive capability. The system instantly detects tire slip and smoothly distributes engine torque to tires with traction. In some cases, the vehicle will anticipate low traction and adjust in order to proactively limit or eliminate slip.
Selec-Terrain is standard with Quadra-Trac II and Quadra-Drive II. Jeep Trail Rated®
All 2011 Jeep Grand Cherokee models equipped with either the Off-road Adventure I or the Off-road Adventure II packages 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.
Jeep Trail Rated is a unique methodology used by Jeep Engineering to measure and predict off-road performance for all Jeep vehicles. Through a combination of natural and controlled field tests, Jeep Trail Rated provides a consistent measurement of off-road performance for all Jeep vehicles. Only Jeep vehicles are Trail Rated.
Classic Exterior Design
Every surface of the all-new Jeep Grand Cherokee is new and treated for aerodynamics. This improves fuel efficiency and puts more fluidity into the design while delivering an 8.5-percent improvement in drag compared with the previous model. The all-new 2011 Grand Cherokee Coefficient of drag (Cd) is approximately 0.37 compared with the previous model's Cd of 0.404.
"Our all-new 2011 Jeep Grand Cherokee is much more refined, focused and sportier than the model it replaces," said Ralph Gilles, Senior Vice President -- Product Design, Chrysler Group LLC. "It has classic Jeep Grand Cherokee styling with sculpted athletic exterior refinements for 2011."
The front includes Jeep's classic seven-slot grille, round headlamps and trapezoidal wheel arches. The removable lower front fascia delivers improved fuel economy, on-road performance and off-road capability. The lower front fascia features a large chromed applique (Limited and Overland models) that showcases available tow hooks.
From the side, Jeep Grand Cherokee features an athletic, muscular profile. Black appliques on B-pillars give the bright day-light opening (DLO) an aerodynamic, modern appearance and a sleek profile. Available chromed mirrors and door handles add to the profile and complement the full-chromed DLO surround on all models.
Standard 17-and 18-inch wheels deliver off-road capability, along with all-new to Jeep, optional 20-inch wheels for 2011.
Taillamps wrap from the rear quarter panel to the back of the vehicle and create a solid form which achieves a more upscale appearance. The treatment complements the front-end design and resonates with the rest of the exterior.
Jeep Grand Cherokee models equipped with the 5.7-liter MDS V-8 engine have 3.5-inch dual chromed exhaust tips, and those with the V-6 engine have a 3-inch single exhaust with optional 3.5-inch chromed tips.
World-class Interior Refinement
The all-new interior features rich materials and elegant appointments, as well as more room for both passengers and cargo.
"Following in the footsteps of the benchmark 2009 Dodge Ram, the all-new 2011 Jeep Grand Cherokee is another proud graduate of our Advanced Interior Design Studio," said Gilles. "We achieved a world-class interior by using fine materials and maintaining a more focused attention to detail."
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 may 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 three inches wider for improved handling and packaging.
Larger front door openings (1.9 inches wider; 2 inches higher) and rear doors that open 78 degrees (compared to previous model's 67 degrees) provide better access to the interior.
Inside, premium seating includes room for five passengers. An available fold-flat front-passenger seat provides improved cargo storage room (Laredo E models).
For maximum cargo and passenger comfort, rear seat backs move a total of 18 degrees front to back.
Cargo volume behind the second row provides an additional 5.6 cubic feet of room (35.1 cubic feet total) compared to the previous model. The well-appointed rear cargo area includes a storage unit with a removable/rechargeable flashlight and new and improved grocery hooks on both sides. The spare tire compartment includes removable dual storage bins for secure storage of muddy gear or other items.
An all-new power rear liftgate is available for effortless remote up/down convenience.

The all-new 2011 Jeep Grand Cherokee is built at the nearly 3-million-square-foot Jefferson North Assembly Plant (JNAP) in Detroit, which has been the site of Grand Cherokee production since its introduction in 1992.
In preparation for production of the all-new Grand Cherokee, JNAP went through a complete transformation as part of World Class Manufacturing (WCM), an extensive and thorough process to restore all Chrysler Group facilities to their original and maximum functionality. Part of that transformation included the addition of a 285,000-square-foot expansion to replace the existing body shop, one piece of Chrysler's investment of approximately $1.8 billion in new vehicle programs.
During the fall of 2009 the JNAP workforce went to work focusing on ways to improve the look and functionality of the plant. They made significant changes in workplace organization and logistics systems, found ways to improve quality, and addressed ergonomic issues.
Taking the transformation one step further, more than 1,400 hourly and salaried employees participated in more than 44,000 hours of training in preparation for launch and submitted over 2,500 suggestions on how to further improve the processes to ensure the highest quality Grand Cherokee rolls off the line. These changes, throughout paint and assembly operations, have given the facility an all-new level of manufacturing flexibility for multiple product capability.
"Restoring Jefferson North helps to maintain and increase the longevity of the facility and secures a future for our employees, our suppliers and the local community," said Scott Garberding, Senior Vice President--Manufacturing/World Class Manufacturing, Chrysler Group LLC. "The results show the commitment, dedication, passion and pride of our employees and further demonstrate our commitment to the City of Detroit and the State of Michigan."
JNAP was built in 1991 and was expanded in 1999. Jeep Brand
