How does the engine start/stop feature in the Audi A1 work?

I am aware that the Audi A1 has a start/stop feature that turns off the engine when the car is idle. But how exactly does this feature work and what are its benefits?

The engine start/stop feature in the Audi A1 works by automatically turning off the engine when the car is at a complete stop and then restarting it when the driver releases the brake pedal. This is done to reduce fuel consumption and emissions, giving you better fuel efficiency and a more eco-friendly ride.

The start/stop feature in the Audi A1 uses a special starter that is able to restart the engine quickly after it shuts off. This allows for a seamless driving experience and saves you the hassle of having to continuously turn the engine on and off in stop and go traffic.
