Electric Power Steering.
The steering with electrical steering support provides an optimum steering feel. It is less sensitive to bumps, while active anti-roll damping reliably evens out oscillating movements. You can make the steering characteristics tighter at any time using the optional sport switch.
Unlike conventional power steering, the steering with electrical support doesn't use a hydraulic system but an intelligent solution based on an electric motor. The benefit: The motor only operates when steering support is actually required - in other words when the steering wheel is moved. When driving straight ahead - which accounts for 90 per cent of any trip, statistically speaking - it remains inactive and doesn't use up any energy at all. The result: the steering with electrical support reduces the average fuel consumption of the car by about 0.3 litres/100 kilometres as compared to cars with hydraulic systems, making an important contribution to increasing efficiency. Since there is no hydraulic oil, maintenance and environmental pollution are also reduced.
In some models you can combine the steering system with Servotronic. This permanently adjusts steering power to the car's speed. To do this, it calculates the support necessary for the speed measured, and the motor of the electrical steering support is supplied with power accordingly. When steering at low speeds, for example through narrow, winding alleys, only minimal force is required. As speed increases, however, the steering support required is reduced continuously so as to ensure more direct contact with the road and therefore optimum directional stability.
