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

I am looking to purchase a new Audi model and I am confused about the difference between the Quattro and Quattro S Line. Can anyone explain it to me?

The Audi Quattro and Quattro S Line are both all-wheel drive systems, but the Quattro S Line is a high-performance version with additional features such as a sport-tuned suspension and upgraded brakes.

The main difference between the Audi Quattro and Quattro S Line is in the design and styling. The Quattro S Line has a more aggressive and sportier appearance compared to the regular Quattro model.

The Quattro S Line is also available in certain models and trims, while the regular Quattro is a standard feature on most Audi vehicles. Overall, the Quattro S Line provides a more engaging and dynamic driving experience.
