What are the key differences between the Audi A8 and A6?

I am trying to decide between purchasing the Audi A8 or A6. What are the main differences between these two models in terms of performance, features, and price?

The Audi A8 definitely offers more power and luxury compared to the A6. It has a larger engine, better handling, and more upscale features such as massaging seats and a 360-degree camera system. However, the A6 has a lower starting price and still offers a comfortable and enjoyable driving experience.
