What is the difference between Audi Quattro and Audi S-Line?

I'm considering purchasing an Audi but I'm confused about the different trim levels. Can anyone explain the difference between Audi Quattro and Audi S-Line?

Audi Quattro refers to the all-wheel-drive system, while Audi S-Line is a trim level that primarily focuses on sportier design elements and features. So it depends on whether you prioritize performance or aesthetics.

The Quattro system is standard on most Audi models and provides better traction and stability, especially in poor weather conditions. S-Line is more of a cosmetic upgrade, offering enhanced exterior and interior styling.
