What is the difference between the Audi A8 and the S8?

I am looking for a high-end luxury sedan and considering the Audi A8 and the S8. Can anyone explain the differences between them in terms of performance, features, and pricing?

The Audi A8 and the S8 are both top-of-the-line sedans from Audi. The main difference between them is that the S8 is the high-performance version of the A8, offering a more powerful engine and sportier handling. However, this also means that the S8 comes at a higher price point than the A8.
