Servotronic
Concept
Servotronic is a speed-dependent power
steering function.
The system provides the steering force with
more support at low speeds than at higher
ones. This makes it easier to park, for instance,
and makes steering more direct when driving
at faster speeds.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel or a comfortable steering response
is conveyed.
