Dynamic Traction Control.
With Dynamic Traction Control (DTC) in the BMW X1, traction increases on loose gravel or snow by improving tolerance for wheel slip.
If the front wheels are stuck in snow and cannot spin properly, this leads to slip on the rear wheels and DSC acts to change engine output: the power needed for forward movement is reduced. Switching to DTC has a positive effect on this situation, as traction is improved without a loss of power. DTC allows you to drive at the limits without fear of exceeding them. It increases wheel slip on the drive wheels in order to ensure optimum traction on any surface. This allows the behaviour of the BMW X1 to be controlled entirely by the driver, with the DSC system taking a back seat. Drivers who appreciate a more sporting driving style can activate DTC to allow for controlled wheel skid, or "drift".
