奥迪A8和奥迪S8有什么区别？

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.
