What are the differences between the Audi A8 and S8 models?

I am interested in buying an Audi A8, but I'm not sure if the S8 model would be a better choice. Can someone explain the technical details and features that differentiate these two models?

The main difference between the Audi A8 and S8 models is the engine. The S8 has a more powerful V8 engine which allows for quicker acceleration and higher top speed. If you care about performance, the S8 would be a better option.

While both the Audi A8 and S8 have luxurious interiors, the S8 has been designed with a sportier feel. If you value a more aggressive and dynamic driving experience, go for the S8.
