What is the difference between Audi S and RS series?

I'm trying to decide between an Audi S model and an RS model, but I'm not sure what the main differences are. Can someone explain the key differences between these two series?

The Audi S series focuses on high performance, while the RS series takes performance to the next level with advanced technology and luxury features. If you want a balance of performance and comfort, go for the S series. But if you want the ultimate driving experience, go for the RS.

One key difference is the engine power - the RS series typically has a more powerful engine, resulting in faster acceleration and higher top speeds. The RS also has more advanced suspension and braking systems, making it better suited for track driving.

In terms of design, the S series has a more subtle and understated look, while the RS series has a more aggressive and sporty appearance. It really depends on your personal style and preference.
