An end to unnecessary idling.

Auto Start Stop function
in the BMW 5 Series Gran Turismo.

Red lights, traffic jams, road works – in everyday driving situations there are countless instances where the engine is idling, unnecessarily burning fuel. This is prevented by the Auto Start Stop function. It switches off the engine when the vehicle is not moving and the driver applies the brakes. The intelligent electronics system has already calculated how much the battery is charged and if other systems – such as the air conditioning or rear windscreen heating – require more energy. When the journey continues, the engine is started immediately when the driver releases the brakes.
