Transfer Case - V8 S/C 5.0L Petrol: Overview

The transfer case enables the vehicle to operate in Rear Wheel Drive (RWD) or All Wheel Drive (AWD).

The transfer case operates in RWD condition until the traction control system detects that the rear tires are approaching their traction limit. If the rear tires are on their traction limit, the transfer case system transition into an AWD condition. The change between the RWD and AWD is controlled by the Transfer Case Control Module (TCCM).

The AWD system is designed to intervene earlier than the Dynamic Stability Control (DSC) system, to provide greater stability and traction. This is achieved by distributing torque to the differential with the most available grip during traction events to maximize traction. This then reduces the amount of intervention required by the DSC system.

NOTE: The Transfer Case Control Module (TCCM) distributes torque to the differential with the most grip during low speed traction events.

The continuously variable AWD system also has the added benefit of being more fuel efficient than permanent AWD systems.
