What is the difference between the S-line and S5 models in the Audi A5 range?

I am considering purchasing an Audi A5, but I am confused about the different models available. What makes the S-line and S5 models different from each other? Is it just cosmetic or are there performance differences?

The S-line model is a sportier version of the Audi A5, with enhanced exterior styling and a more aggressive look. The S5, on the other hand, is a high-performance variant with a more powerful engine and upgraded suspension.

In addition to the cosmetic differences, the S5 also has additional performance features such as quattro all-wheel drive and a sport-tuned suspension. This results in a more dynamic driving experience compared to the S-line model.
