What is the difference between the Audi A8 and S8?

I am considering purchasing an Audi but I'm not sure which model to choose. Can someone explain the specific differences between the A8 and S8?

The Audi A8 is the standard base model while the S8 is the sportier, high-performance version. This means that the S8 has a more powerful engine and improved handling for a more dynamic driving experience. However, the A8 may be a more practical choice for everyday use.

One major difference between the A8 and S8 is their price point. The S8 is significantly more expensive due to its upgraded features and performance capabilities. So if budget is a concern, the A8 may be a better choice.
