What is the difference between Audi A8 and Audi S8?

I am considering buying a luxury sedan from Audi, but I'm not sure what sets apart the A8 and the S8 models. Can someone explain the technical differences between the two?

The main difference between the Audi A8 and S8 is their engine. The A8 comes with a V6 turbocharged engine, while the S8 comes with a V8 twin-turbocharged engine. In terms of performance, the S8 has more power with a 0-60 mph time of 3.7 seconds compared to the A8's 5.6 seconds.

Another notable difference between the A8 and S8 is their exterior design. The S8 has a more sporty and aggressive appearance with its larger air intakes and quad exhaust pipes. The A8, on the other hand, has a more refined and elegant design.

In addition to the engine and exterior design, the S8 also comes with a few performance-enhancing features such as a sport-tuned suspension and dynamic steering. These features are not available on the A8.
