Why does the Audi A6 have a CVT transmission?

I've noticed that most Audi vehicles have traditional automatic transmissions, but the A6 uses a CVT. What are the advantages of this type of transmission and how does it differ from a traditional automatic?

The Audi A6 utilizes a CVT (Continuously Variable Transmission) because it offers smoother and more efficient performance compared to traditional automatic transmissions. The CVT does not have gears, which allows it to seamlessly adjust to the engine's power output, resulting in improved fuel efficiency. It also allows for smoother acceleration and a more comfortable driving experience. As for the major difference, traditional automatic transmissions have a set number of gears while a CVT has an infinite number of gear ratios.
