HOW TO USE THE M TRACTION CONTROL.

1.

BMW M3

Deactivate the Dynamic Stability Control DSC. To do this, press the key beside the gear lever for at least four seconds.
Now open the Setup menu using the key in the central console. Here you’ll find the controls for the M Traction Control.

Now you can set your desired level. The higher it is, the less rear wheel-slip the system will allow. Which means the less the car will drift. M Traction Control can thus serve as an effective aid to traction – for instance to accelerate faster out of bends on racetracks.

If you select a low level, the slip control is opened wider. The ensuing higher level of slip on the rear wheels enables the engine torque to make the car oversteer and start drifting. Thanks to the ten-step system, you can approach a complete oversteer cautiously and gradually. There’s more info in our How-to on the BMW M Drift Analyser.
