2011 Jeep Grand Cherokee

(continued from above)

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 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.

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.
