Electromechanical power steering.
Electromechanical power steering provides maximum manoeuvring comfort with reduced fuel consumption, because, as part of the BMW EfficientDynamics strategy, it only requires energy when it is really used.
While conventional hydraulic systems constantly draw power from the engine - thereby consuming extra fuel - the electromechanical power steering only actually works when the steering wheel is moved. On long straight stretches or when the steering angle is constant during a long bend, the electric motor is not active and therefore cannot use any energy. Active roll damping additionally enhances driving safety in the higher speed range. The Driving Experience Control provides a choice between the steering settings of “Normal” and “Sporty”. Servotronic, the speed-dependent steering support, is also contained in this innovative standard feature.
