How does automatic engine start-stop work in an Audi A6?

I'm interested to know more about the technology behind Audi's automatic engine start-stop feature. How does it work and is it beneficial for the car's performance and fuel efficiency?

The automatic engine start-stop feature in Audi A6 works by shutting off the engine when the car comes to a complete stop, such as at a red light. This reduces unnecessary idling and improves fuel efficiency. Once the brake pedal is released, the engine starts up again seamlessly. You can also turn off this feature if desired.

Audi's automatic engine start-stop feature works by monitoring various factors such as ambient temperature, battery charge, and engine load to determine if the car should shut off the engine. This helps to reduce emissions and prolong the life of the car's battery and starter motor.
