BorgWarner has secured contracts to supply its electric cross differential (eXD) to three major automotive OEMs, including GAC Motor, an unnamed Global OEM based in East Asia, and an unnamed global OEM based in Europe.
The companies will incorporate BorgWarner’s eXD technology on both rear- and front-wheel-drive battery electric vehicle (BEV) applications ranging from sports cars to premium sedans to hatchbacks. Production for GAC Motor is currently underway, and production for the other OEMs will begin in 2026.
eXD is part of BorgWarner’s electric torque management system (eTMS) portfolio, which can intelligently control wheel torque to increase stability, improve vehicle dynamic performance, and improve traction during launch and acceleration.
High torque from the motor in electric vehicles (EVs) leads to limitations and challenges in vehicle performance since the application of torque to individual wheels remains unsupervised. Adding an eXD to the drive system enables intelligent modulation of the side-to-side torque, resulting in improved traction, cornering and lane-change performance, all with improved efficiency.
The eXD technology can be applied on all vehicle architectures, including front and rear drive units for electric, hybrid and ICE vehicles, and offers a range of selectable modes depending on vehicle performance needs. As a scalable and customisable technology, customers can program different performance characteristics and behaviours for their respective platforms.
The eXD enables intelligent communication with the vehicle, operating on-demand and featuring an on-board integrated controller that supports requirements ranging from cyber security to functional safety and beyond. Additionally, by adaptively controlling wheel slip, the eXD decreases brake system utilisation and thus the emission of non-exhaust particulate matter to the environment.
