BMW X1 2012 vs BMW X1 2011

BMW X1 2012: BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes unstable, unnoticed by the driver. Torque is distributed between the axles via an electronically controlled multi-plate clutch located in the transfer case. Most of the time, the clutch is partially locked and power is transferred 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 high speeds or when parking, for example, the clutch is disengaged and all power is sent to the rear wheels. DSC (Dynamic Stability Control) also brakes the wheels individually to regain traction and assist in cornering.
