M Servotronic is a special form of power steering geared not to engine speed, like conventional power steering systems, but rather to the car's actual road speed.
In practice this means ample power assistance when parking and manoeuvring at low speeds, followed by gradual reduction of power assistance as road speed increases to ensure greater direct contact with the road at high speeds and, as a result, an even higher standard of steering precision. Using the sports switch, the driver can also choose a second steering control curve for even sportier feedback from the steering.
