3 New Full Time 4WD Systems
Quadra-Trac: Utilizes a single-speed transfer case to provide full-time 4WD--no driver interaction is required.
Quadra-Trac II: incorporates the new NV245 transfer case to deliver full-time active 4WD, which anticipates and prevents wheel slip for best traction in many conditions. The transfer case includes electronic shift with a true low-range gear and neutral for towing behind another vehicle.
Quadra-Drive II: uses Electronic Limited Slip Differentials (ELSD) for maximum off-road capabilities. ELSD replace the Vari-Lock progressive axles used on the Quadra-Drive system from previous generation Jeep vehicles and provides greater torque capacity and quicker response to changing conditions.
Engine Availability
- 5.7-liter HEMI V-8 engine
- 3.7-liter SOHC V-6 replaces the 4.0-liter I-6 engine
- 4.7-liter SOHC V-8 engine
Jeep says that its Multi-Displacement System (MDS) deactivates half the cylinders of the 5.7-liter HEMI during cruising and light acceleration to increase fuel economy by up to 20 percent, depending on driving conditions.
With approximately seven percent less displacement, the 3.7-liter V-6 produces more peak power than the 4.0-liter I-6 engine it replaces, while producing comparable torque. The engine was �rst introduced on Jeep Liberty and Dodge Ram models, and shares many design features with the 4.7-liter Power Tech V-8 engine.
New Suspension and Steering System
- Front suspension wheel travel is increased 13 percent over the previous generation vehicle, with a turning diameter of 37.1 ft.
- The new five-link rear suspension geometry, including a track bar, also improves lateral stiffness to match that of the front suspension for optimum handling.
- Electronic Stability Program (ESP) uses signals from sensors throughout the vehicle to make brake and throttle adjustments for directional stability of the vehicle.
Transmissions
- An all-new five-speed automatic transmission is paired with the 3.7-liter V-6.
- The 545RFE five-speed automatic transmission used with the 4.7-liter V-8 and 5.7-liter V-8 HEMI has been refined for higher-quality shifts and to increase maximum towing capacity.
Both transmissions feature Electronic Range Select (ERS) driver interactive shift control. The shifter provides fully-automated shifting when in the "drive" position, but allows the driver to manually select the gear that's best for their off-road driving requirement.
A new stamped steel transfer case skid plate mounts to the transmission cross member and fuel tank skidplate to provide off-road protection to the transfer case.
