BorgWarner has secured a new electric cross differential (eXD) programme with a leading Chinese original equipment manufacturer, marking the company’s first 48V eXD application in its global portfolio. The award expands BorgWarner’s torque management capabilities for electric vehicles and embeds the system within the customer’s 48V electrical and electronic architecture. The programme underscores the company’s strategy to adapt proven driveline technologies for emerging electrified architectures.\n\nA 48V electrical architecture offers advantages including improved energy efficiency, optimised wiring and component costs, and support for higher-power applications. BorgWarner’s electric cross differential is designed to integrate with such architectures and to dynamically control torque distribution between wheels, enhancing handling and traction while maintaining a balance between performance, safety and system efficiency. The solution aims to deliver these benefits across a broad range of vehicle operating conditions.\n\nCompany leadership indicated that securing this programme demonstrates the ability to adapt torque management technologies to new electrical architectures and that leveraging a 48V system is expected to improve energy utilisation, system efficiency and reliability, thereby elevating the driving experience for electric vehicle users. The eXD is engineered to adjust slip control in real time based on driving conditions and vehicle status, supporting stability during high-speed travel, rapid acceleration and sharp turns. Engineers have tuned the system to provide consistent handling across varying road friction levels.\n\nOn dry roads, higher friction enables greater grip, which allows the eXD to transfer more torque to outer wheels to assist cornering performance. In low-friction environments such as ice, snow or mud the system is intended to rapidly detect wheel slip and to limit torque transfer to slipping wheels, reallocating drive force to wheels with better traction to maintain control. The approach is presented as balancing performance, safety and efficiency while meeting customer integration requirements.\n\nFor more than 130 years BorgWarner has positioned itself as a global product leader focused on mobility innovation and sustainability. The company intends to bring the new 48V eXD solution to market in line with industry trends towards more integrated and efficient E/E architectures.
