The core technology xDrive all-wheel drive system is Austria Magne middot; Steyr developed splitter, torque distribution to be adjusted continuously. The system xDrive changing the torque distribution according to the road situation, the respective front and rear wheel torque transmission needed, before and after the default torque split 40:60, before and after the maximum torque distribution ratio is 0: 0: 100 to 100. The system also continues to DSC with dynamic stabilization system exchange information so as to identify from the beginning to wheel slippage. The torque distribution can be completed in 0.1 seconds.
during traveling, if the system finds the vehicle may understeer, the front wheel is started to be dragged outside of the bend, will reducing the torque allocated to the front axle, we have almost all the power delivered to the rear axle. The system also continues to DSC with dynamic stabilization system exchange information so as to identify from the beginning to wheel slippage. Once wheel slip, the motor is locked xDrive-disk clutch and make the wheel has better adhesion by an additional drive torque, while the idle wheels will be effectively controlled braking device. This means that no matter how sudden changes in the road, there will be the right amount of torque is delivered to the best wheel grip, even in part on icy roads.
