What is the V-pulley system and how does it work in an Audi A2?

I am curious about the V-pulley system in my Audi A2. What is its purpose and how is it different from other pulley systems?

The V-pulley system is a set of pulleys and belts that work together to power various components in your Audi A2, such as the alternator and air conditioning. It works by using the friction between the belts and pulleys to transfer power from the engine. It is more efficient and compact compared to other pulley systems like the flat-belt and multi-belt systems.
