Dynamic Stability Control (DSC) is BMW's take on traction control. The system makes sure you always have complete control over your vehicle, by pulling in measurements from around your vehicle — the steering angle, brake amount, individual wheel speed and more — and intelligently adjusting your car's behaviour. That means no wheel spin, no sliding and no loss of control going round turns.
When you don't need such a helping hand, DSC can be disabled. In Sport+ mode, DSC is switched off completely, giving you far more say in how your BMW handles.
