Why does the Audi A6 have automatic start/stop technology?

I noticed that the Audi A6 has automatic start/stop technology, where the engine shuts off when stopped at a traffic light. Can you explain the purpose and benefits of this feature?

The main purpose of automatic start/stop technology in the Audi A6 is to improve fuel efficiency and reduce emissions. By shutting off the engine when the car is stopped, it eliminates unnecessary idling and saves fuel.

In addition to being environmentally friendly, automatic start/stop technology also helps reduce engine wear and tear. Less idling means less wear and tear on engine components, ultimately increasing the lifespan of the engine.

If you find the automatic start/stop technology too intrusive or annoying, you can disable it by pressing the dedicated button on the center console. However, keep in mind that the technology is designed to work seamlessly with the car, so it's recommended to leave it on for optimal efficiency and performance.
