This results in a sporty steering response. In addition, it becomes easier to steer during parking and maneuvering.
Servotronic
The concept The Servotronic varies the steering force required to turn the wheels in accordance with the vehicle speed. At low speeds, the steering force is strongly supported, i. e. during steering, low force is required. As the speed increases, the assistance of the steering force is reduced.
Furthermore, the steering force adapts according to the driving program, so that a direct, sporty feel and/or comfortable steering is conveyed.
