The electro-hydraulically actuated AWD coupling automatically distributes power between the front and rear wheels of the vehicle. In addition to optimising traction and vehicle dynamics under almost all conditions, the technology enhances the vehicle's driveline efficiency, says the company.
It features an Efficient Mode for reduced driveline losses. This is an intelligent valve that manages the clutch lubrication to significantly reduce losses. In this mode, the coupling provides better fuel economy when AWD function is not needed.
The technology is available in the BMW 220d xDrive Active Tourer and the BMW 225i xDrive Active Tourer.
The engineering component company adapted the GenV integrated electronic control module to match the driving characteristics and demanding specifications for improved traction and handling. Software calculates and delivers pre-emptive as well as immediate response with high-torque accuracy based on data supplied by the on-board electronics. Without any driver input, the electronically controlled multi-plate clutch distributes power between the front and rear axles automatically. In addition, it improves fuel economy by providing only the requested amount of torque to the rear axle, optimised for nearly all driving situations. If necessary, full locking torque is available at any given time and speed, depending on road conditions and vehicle load distribution.
