Intelligent energy management.
The intelligent energy management in the BMW X6 is provided by a number of standard-feature BMW EfficientDynamics technologies, including the Automatic Start/Stop function, Electric Power Steering and Brake Energy Regeneration. The interplay between these technologies ensures sustainable mobility and maximum efficiency.
The Automatic Start/Stop function ensures that fuel is only used when the car is moving. When the vehicle comes to a temporary stop, for example at traffic lights or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the car comes to a complete standstill.
A signal in the Info Display indicates when the Automatic Start/Stop function is active. As soon as the foot is taken from the brake, the engine springs back to life automatically.
The function never compromises driving comfort and safety, as it remains inactive if the engine has not reached its optimal running temperature, the interior has not yet been sufficiently heated or cooled, if the battery level is too low or if the steering wheel is being turned. If necessary, a central control unit restarts the engine even when at a standstill, for example if the car begins to roll or if condensation starts to form on the windscreen. The Automatic Start/Stop function can be switched off at any time at the push of a button.
Every time you turn the steering wheel, energy is consumed. But why should energy be consumed when the wheel is not being turned? BMW Electric Power Steering is only active when it’s needed. Unlike conventional hydraulic steering systems, BMW EPS only uses energy when the wheel is actively being turned. When the steering angle is constant, the electric motor remains inactive.
Every time the brakes are hit, kinetic energy is generated and until recently this energy went unused. Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever the driver brakes or takes his or her foot off the accelerator and turns it into electricity. This electricity is then used to charge the car battery. The intelligent energy management system means that the alternator no longer needs to run constantly, which reduces the strain on the generator. The result: reduced fuel consumption and increased performance – classic BMW EfficientDynamics.
