The Servotronic designation consists of the following terms: power steering and electronics. It is so called the speed-dependent control of the power steering (the conventional power steering operates with continuous power assistance).
The lower the car speed is (for example, in urban traffic), the higher the support of the steering. In this way, manoeuvring is considerably much easier when parking.
In the high-speed range, the steering power assistance is reduced; the driver is able to steer more accurately and keep the car safer on track, improving the directional stability.
