BMW 3 series 2015 vs Volkswagen Golf 2012

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.

Volkswagen Golf 2012: It has Haldex Generation V proactive automatic four-wheel drive. The system analyzes input from the ABS and engine control units and can increase pressure on the multi-disc clutch for faster engagement when needed. Under normal driving conditions, the torque split is 100% front to 0% rear. If wheel spin is detected, torque can be split evenly between the axles (50%/50%).
