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

I want to buy a luxury sedan, but I can't decide between the Audi A8 or the S8. What sets these two cars apart and which one offers better value for money?

The main difference between the Audi A8 and the S8 is the engine. The A8 comes with a standard V6 engine, while the S8 has a more powerful V8 engine. Additionally, the S8 offers a sportier driving experience with its stiffer suspension and sport-tuned steering.

Another important factor to consider is the price. The S8 is significantly more expensive than the A8, so if budget is a concern, the A8 might be a better choice. However, the S8 does come with more advanced technology and features, making it worth the extra cost for some buyers.
