BMW 3 sērija 2015: BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes destabilized, unnoticed by the driver. Torque is distributed between the axles by an electronically controlled multi-plate clutch in the transfer case. The clutch is partially locked at most times, distributing power to both axles in a 40/60 front/rear ratio, but the system is capable of sending 100% of the torque to either axle. At higher speeds or when parking, multi-plate clutch is disengaged and all power is transferred to the rear wheels. DSC system (Dynamic Stability Control) also brakes the wheels separately to regain traction and assist in cornering. | |||
