What is the difference between a Audi A5 and a Audi S5?

I'm interested in purchasing an Audi A5, but I'm not sure what sets it apart from the Audi S5. Can someone provide a detailed comparison of the two models?

The main difference between the Audi A5 and the Audi S5 is the engine. The A5 comes with a 2.0-liter 4-cylinder engine while the S5 has a more powerful 3.0-liter V6 engine.

While the A5 and S5 have similar exterior designs, the S5 has sportier features such as a more aggressive front grille and larger air intakes.

In terms of performance, the S5 also has upgraded brakes, suspension, and steering for a more dynamic driving experience.
