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.
