Nearly 18 years ago, Jeep invented the premium 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 real-world 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 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.
"Jeep invented the SUV segment and our all-new Jeep Grand Cherokee is the next step in the evolution of the SUV," said Mike Accavitti, Director - Jeep, Chrysler and Dodge Brands. "Jeep innovations including Quadra-Lift air suspension and Selec-Terrain traction control separate us from the crowd."
Legendary Capability
The all-new Jeep Grand Cherokee offers the new Quadra-Lift air suspension system. The Quadra-Lift 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 1.5 inches for added height in clearing obstacles (9.6 inches)
* Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 3 inches of height for 11.1 inches of ground clearance
* Park Mode: Lowers the vehicle 1.5 inches from NRH for easy ingress/egress. 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 4.5 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).
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 and Quadra-Lift adjust for ultimate performance over snow-covered roads
* Rock: Quadra-Lift suspension raises to maximum height (11.1 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, offers drivers an adjustable suspension span that delivers legendary Trail Rated® performance.
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.
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 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.
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.
