Why does the Audi A8 have a four-zone automatic climate control system?

I've heard that the Audi A8 comes with a four-zone automatic climate control system, but I'm not exactly sure what that means. Can you explain how it works and why it's a feature on this car?

The four-zone automatic climate control system on the Audi A8 allows for each passenger to have control over their own temperature settings. This means that everyone can customize the temperature to their liking without it affecting the rest of the car. This is especially useful if passengers have different preferences or if you're traveling in extreme weather conditions.

Having four climate zones also means that the system can adjust the temperature based on the external climate conditions. This ensures that the interior of your car remains comfortable, regardless of the weather outside. This feature is especially helpful for long drives or when traveling through different climates.
