BorgWarner has secured its first production program for a 48-volt electric cross differential (eXD) with a major Chinese original equipment manufacturer, marking the debut of the technology in its global portfolio. The system will be integrated into the automaker’s existing 48V electrical architecture, expanding BorgWarner’s presence in the rapidly growing electric vehicle market.
The eXD technology is designed to improve traction, stability, and handling by dynamically controlling torque distribution between wheels in real time. According to the company, the system continuously monitors driving conditions and adjusts slip control to maintain vehicle stability, particularly during high-speed maneuvers or challenging road situations.

During cornering on dry surfaces, the system can direct additional torque to the outer wheels to enhance handling. In low-grip environments such as ice or mud, it reallocates drive force to wheels with better traction, helping maintain control. The approach aims to balance safety and performance while improving driver confidence.
BorgWarner said the use of a 48V electrical architecture offers efficiency benefits compared with conventional systems. Higher voltage capability allows support for more powerful applications while reducing wiring weight and associated costs, potentially improving overall energy utilization within the drivetrain.
