BorgWarner has secured a new electric cross differential (eXD) program with a leading Chinese original equipment manufacturer (OEM), marking its first 48V eXD application globally. The solution is designed for integration within a 48V electrical and electronic (E/E) architecture, expanding BorgWarner’s 48V electric vehicle technology portfolio in China and strengthening its torque management capabilities for next-generation electrified vehicles.
Expanding 48V Electrification Capabilities
As the electric vehicle market advances, E/E architectures are increasingly shifting toward higher efficiency and deeper system integration. A 48V architecture offers several advantages, including improved energy efficiency, optimized wiring complexity, lower component costs, and support for higher-power vehicle applications.
BorgWarner’s 48V eXD solution is engineered to integrate seamlessly with the OEM’s 48V E/E system, enabling more compact, cost-effective electrification solutions while delivering enhanced vehicle performance.
Dynamic Torque Distribution for Enhanced Handling
The electric cross differential is designed to dynamically manage torque distribution between wheels, improving handling precision and traction across varying driving conditions. By adjusting slip control in real time based on vehicle speed, driver input, and road conditions, the system supports vehicle stability during high-speed driving, rapid acceleration, and sharp cornering.
On high-friction surfaces such as dry roads, the system is expected to transfer greater torque to the outer wheels during cornering, enhancing grip and overall driving performance. In low-friction environments like snow, ice, or mud, the eXD is designed to quickly detect wheel slip and limit torque delivery to slipping wheels, reallocating power to wheels with better traction to maintain control and stability.
Strengthening Torque Management in Electric Vehicles
With this program award, BorgWarner continues to broaden its electrification portfolio beyond propulsion systems into advanced torque management solutions. The introduction of its first 48V eXD application highlights the company’s commitment to developing scalable, efficiency-focused technologies that support evolving electric vehicle architectures.
The new program further reinforces BorgWarner’s strategic focus on electrification growth in key global markets, particularly in China, where demand for cost-efficient and performance-oriented electric vehicle solutions continues to accelerate.
Leadership Quote
“We believe BorgWarner’s eXD technology enhances handling and vehicle stability across a wide range of driving conditions,” said Isabelle McKenzie, Vice President of BorgWarner Inc. and President and General Manager, Drivetrain and Morse Systems. “Securing our first 48V eXD program demonstrates our ability to adapt proven torque management technologies to new electrical architectures. By leveraging a 48V system, the eXD is expected to improve energy utilization, system efficiency, and reliability, which will elevate the driving experience for electric vehicle users.”
