| Three new full-time four-wheel-drive systems are available on Grand Cherokee: Quadra-Trac® I utilizes the NV140 single-speed transfer case to provide convenient full-time four-wheel drive with no transfer case lever to shift or driver interaction required. Offering a single-speed transfer case attracts a new group of buyers to the Jeep Grand Cherokee lineup and builds on the capable, entry-level, two-wheel drive versions, which currently account for approximately 25 percent of Jeep vehicle sales.
Quadra-Trac® II incorporates the new NV245 transfer case that provides full-time active four-wheel drive, which anticipates and prevents wheel slip for optimum traction during a wide range of conditions. The NV245 also includes electronic shift with a true low-range gear and neutral for towing Grand Cherokee behind another vehicle. Quadra-Drive® II takes unparalleled Jeep capability to an even higher plateau using Electronic Limited Slip Differentials (ELSD) to give customers the ultimate in off-road capability. ELSD replace the Vari-Lock progressive axles used on the Quadra-Drive system from previous generation Jeep vehicles for even quicker response to changing conditions and greater torque capacity. |
