What is the difference between Audi A7 Sportback and Audi A7 Sportback S line?

I am planning to buy an Audi A7 but I'm not sure what the difference is between the Sportback and the Sportback S line. Can someone explain it to me?

The main difference between the Audi A7 Sportback and Sportback S line is in their design and features. While the Sportback is more focused on luxury and comfort, the Sportback S line has a sportier look and feel with added performance features.

In terms of design, the A7 Sportback S line has a more aggressive front bumper and side sills, as well as larger wheels and a sportier suspension. It also includes features such as a rear diffuser and aluminum trim.

On the other hand, the A7 Sportback focuses more on luxurious features such as a panoramic sunroof, power soft-closing doors, and extended leather upholstery. It also has a more comfortable suspension for a smoother ride.
