What is the difference between Audi S line and RS models?

I am looking to purchase a new Audi car and I am wondering what distinguishes the S line and RS models?

The S line models offer sportier design and features, while the RS models are high-performance versions with even more advanced technology and handling capabilities.

The S line models are more affordable and suitable for everyday driving, while the RS models are designed for track racing and better suited for experienced drivers.

The key differences between Audi S line and RS models lie in their engines, transmissions, and suspension systems. The RS models have more powerful engines, quicker shifting transmissions, and stiffer suspensions for better handling.
