ONLY BMW CAN! Not Mercedes Benz, not Audi, Not Acura, Not Lexus. ONLY BMW!!! Brandon Kim only sells the best car in the world. ULTIMATE DRIVING MACHINE!!! Dont you agree that BMW Xdrive system is the best all wheel drive system? Only BMW offers 100% front wheel drive or 100% rear wheel drive!!! Instead of a permanent torque split (which the earlier systems feature), xDrive provides variable torque split between the front and rear axles through the use of a multi-plate wet clutch located in thegearbox on the output to the front drive shaft. This setup allows xDrive to modulate the torque split between the front and the rear axles, which is normally split at 40:60 ratio. If wheel slip is detected by the ABS/DSC system, xDrive can react within a tenth of a second to redistribute up to 100% of the engine power to the front or rear axle.[1] The wet clutch is applied through a high speed electric servo motor turning a cam shaped actuator disc. xDrive is connected to the ABS and DSC systems. In the case that wheelspin or directional instability still occurs while xDrive is or has been modulating the torque split, DSC will brake independent wheels to regain traction and improve directional stability without driver intervention. The front and rear differentials in xDrive vehicles are an open differential design, thus relying on brake application by the DSC system to transfer power from the slipping wheel to the wheel with traction.
