What is the difference between the Audi S8 variants?

While the A8 focuses on providing a serene and elegant executive experience with a V6 engine, the S8 is the high-performance flagship that comes standard with a potent twin-turbo V8, more aggressive S-specific exterior styling like quad exhaust tailpipes, and advanced driving technologies such as predictive active suspension and dynamic all-wheel steering that are often optional or unavailable on the standard A8. For buyers considering the Audi S8, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
