Auto Start Stop function.
Red lights, traffic jams, level crossings – 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.
The Auto Start Stop function switches off the engine when the BMW M5 Sedan is not moving. The intelligent electronics system has already calculated and checked the charge level of battery and whether other systems – such as the air conditioning or rear windscreen heating – require more energy. Releasing the footbrake starts up the motor almost instantly so that the journey can continue.
