The braking, traction, e-diff, ect. is now all electronically actuated, instead of hydraulically controlled, which now allows them to individually modulate the vehicle’s stability and traction with a lot more precision and end-user fine tuning abilities.


Yup, got that part. How does M Traction control level 10 differ from MDM?


I don’t know how else to explain it to you; it now limits/allows the slippage and traction into different intervals from a deviation of 1 to 10 in severity, in a more linear fashion, instead of just on/off as with regular MDM, which was essential 1 – 2. Since the brakes are now electronically actuated, the slippage, yaw, vehicle angle, ect. can now be instantly modulated, allowing for a higher-level locking intervention to stabilize and enhance the vehicle’s dynamics.
