BorgWarner has appended contracts to supply its electric cross differential (eXD) to three major OEMs, involving GAC Motor, a global East Asian OEM, and a global OEM based in Europe. The companies will assimilate BorgWarner’s eXD technology on both rear- and front-wheel-drive battery electric vehicle (BEV) applications extenting from sports cars to premium sedans to hatchbacks. Construction for GAC Motor is currently underway, and production for the other OEMs will begin in 2026.
The electric torque management system (eTMS) portfolio from BorgWarner includes the eXD, a set of devices that dynamically regulate wheel torque to enhance traction, boost stability, and deliver better dynamic performance during launch and acceleration. Since the torque is applied to each wheel independently, high motor torque in electric cars (EVs) causes restrictions and difficulties in the vehicle’s performance.
It is essential to add an eXD to the drive system because it allows for intelligent torque modulation from side to side, which improves traction, cornering, and lane change performance all at the same time with increased efficiency. In challenging driving situations, the eXD system can significantly and energy-efficiently improve driving safety.
Isabelle McKenzie, President and General Manager of BorgWarner Drivetrain and Morse Systems, stated that “BorgWarner’s eTMS portfolio leverages an array of BorgWarner’s longstanding and proven competencies within the industry, spanning software, controls, systems integration, and beyond.” “The recent business awards for our eXD technology highlight our ability to meet the industry’s need for solutions that increase safety and optimize energy consumption, as well as the versatility and sophistication of the system.”
With a wide range of selectable modes based on vehicle performance requirements, BorgWarner’s eXD technology is compatible with all architectures, including front and rear drive units for electric, hybrid, and internal combustion engine vehicles. Since the technology is fully scalable and configurable, users can program various performance traits and behaviors for the platforms that suit them best. Based on a platform development methodology and robust heritage BorgWarner know-how, the eXD uses carry-over components for both hardware and software.
Operating on-demand and equipped with an on-board integrated controller that covers requirements ranging from cyber security to functional safety and beyond, the eXD facilitates intelligent and efficient connection with the vehicle. Furthermore, the eXD reduces brake system consumption and consequently the amount of non-exhaust particulate matter released into the atmosphere by adaptively limiting wheel slip.
