Description And Operation: Overview

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

The Intelligent Driveline Dynamics (IDD) system is an All Wheel Drive (AWD) system that optimizes torque distribution between the front and rear axles depending on road surface and driving conditions.

The driveline system operates in Rear Wheel Drive (RWD) condition until the system detects that the rear tires are approaching their traction limit. If the rear tires are on their traction limit, the system transition into an AWD condition.

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 during traction events to maximize traction and reduce the amount of intervention required by the stability control system.

NOTE: The system only distributes torque to the axle with most grip during low speed traction events. Dynamically, the system operates with a fairly fixed torque distribution.

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