Volkswagen Golf 2009 vs BMW 3 series 2008

Volkswagen Golf 2009: It has Haldex Generation IV automatic proactive all-wheel drive. Haldex analyzes data from the ABS control unit and the engine control unit and can increase the pressure on the multi-plate clutch for faster activation when needed. It has a 100% front to 0% rear torque split when not engaged with a max 50/50 torque split.

BMW 3 sērija 2008: 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 most of the time, 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 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.
