ELECTRIC POWER STEERING.

ELECTRIC POWER STEERING.

The Electric Power Steering only activates when it’s needed: when you’re turning the wheel. The energy it requires has previously been extracted by Brake Energy Regeneration from the braking and kinetic energy.
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.

BRAKE ENERGY REGENERATION.

Until now, braking had meant giving away energy. Brake Energy Regeneration puts an end to this by using energy gained during braking to charge the battery.
As soon as you release the accelerator or apply the brake, Brake Energy Regeneration uses the energy liberated to charge the battery. This unburdens the engine and reduces emissions.
The targeted generation of electrical energy also has another advantage: At full acceleration, the engine also has the propulsive force at its disposal that would otherwise be channelled off to charge the battery in conventional systems. The result is an increase in not only cost-efficiency but also driving fun.
