How does the start-stop system work in the Audi A7?

I've noticed that my Audi A7 has a start-stop system when I come to a stop. How does this system work and is it beneficial for my car?

The start-stop system in the Audi A7 is designed to automatically shut off the engine when the vehicle comes to a complete stop and then restarts it when the driver releases the brake pedal. This helps reduce fuel consumption and emissions by reducing the amount of time the engine is idling.

Additionally, the start-stop system also helps reduce wear and tear on the engine, as it is not constantly running when the car is stopped. This can ultimately extend the life of your Audi A7.
