2011 Jeep Grand Cherokee

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 delivers the ultimate combination of Jeep 4x4 capability and on-road refinement with the all-new 2011 Jeep Grand Cherokee.

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™ air suspension system delivers legendary Jeep off-road capability along with the new Selec-Terrain™ system which 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 2011 Jeep Grand Cherokee Laredo X and Laredo E are available with a new all-weather package. The all-weather package includes Jeep’s new Select-Terrain™ system for adjusting the traction control system to match road conditions, a two-speed transfer case with low-range, an engine block heater for extreme cold weather, daytime running lamps, remote start, tow hooks and Mopar slush mats and cargo liner.

“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.”

Legendary 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 lightweight 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.

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 appliqué (Limited and Overland models) that showcases available tow hooks. From the side, Jeep Grand Cherokee features an athletic, muscular profile. Black appliqués on B-pillars give the bright daylight 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 (standard on Overland and optional on Limited).

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 multi-displacement system (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.

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 sunroof provides twice as much glass surface than a standard sunroof 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 sunshade.

Engineering

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 legroom. The vehicle also is 3 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 12 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.

Continuing to build on the Jeep brand’s legendary off-road capability, the all-new 2011 Jeep Grand Cherokee adds premium on-road performance to complete the package.

The all-new 2011 Jeep Grand Cherokee’s premium SUV on-road manners and legendary Jeep ruggedness is achieved with more than 5,400 welds in the body alone. Torsional stiffness is 146 percent stiffer than the previous Grand Cherokee and stiffer than the BMW X5 and Toyota Highlander for improved durability and reduced noise, vibration and harshness (NVH).

More than 3,700 mm of arc welding and 100 m of structural adhesive augment the welding. This marks a 53-percent increase in spot welds, a 42-percent increase in arc welds and a 38-percent increase in structural adhesive.

The all-new 2011 Jeep Grand Cherokee is available with two leading engine options for North American markets.
