Mercedes-Benz M-Class 4ETS system
MB's claim, 4 ETS would stop spinning wheels and
direct all available torque (up to 100%) to the wheel(s) with traction, does not hit the nail on the head.
Due to 4 ETS intervention, after a brief moment of traction loss, spinning wheels are slowed down
and the differentials will again distribute a higher amount of torque to all four wheels.
see detailed description
If only one wheel has traction it receives 25% of the available torque.
75% of the torque is transformed into heat.
If two wheels have traction, they receive 50% of the available torque.
50% of the torque is transformed into heat.
If three wheels have traction, they receive 75% of the available torque.
25% of the torque is transformed into heat.

4ETS keeps you moving, while ESP keeps you moving in the direction you intended the vehicle to go.
