How does the automatic start-stop function work in a BMW M9?

I recently purchased a BMW M9 and noticed that it has an automatic start-stop function. Can someone explain how this feature works and if it has any impact on the performance of the car?

The automatic start-stop function in the BMW M9 is a fuel-saving feature that turns off the engine when the car is idle, such as at a red light or in heavy traffic. This helps reduce fuel consumption and emissions. Once you release the brake pedal, the engine will automatically restart. This does not have any significant impact on the performance of the car.

It's really simple - every time you come to a stop, the engine will automatically turn off. As soon as you release the brake pedal, it will turn back on. This feature is great for city driving and can save you a lot of gas in the long run.
