What are the differences between the Audi A5 and S5 trim levels?

I am considering purchasing an Audi A5 but I am also interested in the S5 trim. What are the main differences between these two models? What performance and design features set them apart?

The Audi A5 has a more economical engine choice while the S5 has a more powerful V6 engine. Additionally, the S5 has standard Quattro All-Wheel Drive for improved handling and performance.

The S5 has a sportier and more aggressive exterior design with larger wheels and unique styling elements. It also has a sport-tuned suspension for a more spirited driving experience.

The interior of the S5 features higher quality materials and sport seats for a more luxurious and comfortable experience. It also has standard technology features such as a virtual cockpit and larger touchscreen display.
