The electromechanical power steering system only activates when it's needed: when you're turning the wheel. It draws electrical power from the battery, which Brake Energy Regeneration has previously captured from the vehicle's kinetic energy.More
This element of BMW EfficientDynamics replaces the conventional hydraulic power-steering system with an electric motor. While hydraulic systems constantly draw power from the engine – thereby consuming extra fuel – the innovative BMW system only springs into action when it's actually needed. If you don't move the steering wheel (on a straight, for example, or on a steady curve) the electric motor remains inactive, reducing power consumption.
