Audi A4 2004: The vehicle features full-time Quattro IV all-wheel drive with Torsen center differential and electronic traction control that operates at speeds up to 40 km/h and applies brakes to spinning wheels, with the effect of locking the front and rear differential.
BMW 3 sērija 2005: 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.
