BorgWarner has secured a new programme for its electric cross differential (eXD) technology for an unspecified “leading Chinese original equipment manufacturer (OEM)”, to be used in electric vehicles in China. As the electric vehicle market evolves, traditional powertrain technologies are transitioning towards advanced electrification solutions to meet increasing performance and safety demands. eXD is designed to improve handling and traction capabilities by dynamically controlling power distribution between the wheels.
eXD dynamically adjusts slip-control based on real-time driving conditions and vehicle status, enhancing vehicle stability during high-speed driving, rapid acceleration, and sharp turns.
According to BorgWarner, the eXD also has ‘superior handling performance’ across varying friction conditions. For example, on dry roads, higher friction allows for improved grip, enabling the eXD to transfer more power to the outer wheels for enhanced cornering performance. In slippery conditions such as ice, snow or mud, the eXD rapidly identifies reduced friction and limits power transfer to any slipping wheels, reallocating drive force to the wheels with better traction in order to ensure stability and control.
“BorgWarner’s eXD technology improves handling and vehicle stability in various driving conditions,” said Isabelle McKenzie, vice president of BorgWarner Inc. and president and general manager, Drivetrain and Morse Systems. “The technology has proven effective in high-performance combustion vehicles, and we are now expanding its application to electric vehicles to elevate the driving experience for electric vehicle users.”
