Description And Operation: Overview

WARNING: This page is about a different car, the 2018 Jaguar XF and 2017 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The All-Wheel Drive (AWD) system is an intelligent torque on-demand system which is continuously variable.

The vehicle's driveline system operates in an AWD condition until the system determines that traction conditions are acceptable to operate in a Rear Wheel Drive (RWD) condition. If wheel slip is then encountered when in RWD the driveline system will then return to AWD.

The system automatically routes torque to all four wheels, varying the distribution between front and rear axles as necessary.

The design includes several innovative features, for example:

The AWD system is designed to intervene earlier than the stability control system, to provide greater stability and traction. This is achieved by distributing torque to the axle with the most available grip to maximize traction and reduce the amount of intervention required by the stability control system.

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