With the BMW xDrive four-wheel drive system, each axle uses its traction to the maximum. Your BMW provides stable acceleration out of bends. If – particularly in adverse conditions – more torque has to be applied to the road, that’s when Dynamic Stability Control (DSC) comes into operation. In addition to improving traction, the system also recognises the first signs of oversteering and understeering. Within a tenth of a second it distributes up to almost 100% of the engine torque to the front or rear axle via the transmission and an electronically controlled multiple-plate clutch before returning to the normal 40:60 distribution ratio.
The xDrive four-wheel drive system fitted to 2 Series Active Tourer, 2 Series Gran Tourer and X1 models has the ability to send up to 100% of drive to either the front or rear axle. For example, while trying to pull away on wet grass, the intelligent system could detect slippage on the front axle. It would then send power to the rear axle where there’s more grip, making pulling away safe and easy. Coupled with BMW Performance Control, which applies targeted braking in corners by diverting more power to the outer wheels and less to the inner wheels, these systems improve driving safety and provide BMW’s trademark dynamic agility.
With this technology, BMW provides an intelligent four-wheel drive system with all the benefits of four-wheel drive: precise handling, optimum cornering and a clear separation between the engine and steering.
