What is the difference between the Audi A4 and S4 models?

I am considering purchasing an Audi A4 or S4, but I am not sure which one would be a better fit for me. Can you explain the main differences between these two models and which one would be more suitable for my needs?

The main difference between the Audi A4 and S4 models lies in their performance. The S4 is equipped with a more powerful engine and has a sportier suspension, making it a better option for those looking for a more exhilarating driving experience. However, if you prioritize fuel efficiency and a smoother ride, the A4 may be a better choice for you.

Apart from their performance, the A4 and S4 also differ in their exterior design and features. The S4 has a more aggressive and sporty look, while the A4 has a sleeker and more elegant design. Additionally, the S4 comes standard with features like leather seats, upgraded infotainment system, and adaptive suspension, which may be appealing to those looking for a more premium and luxurious driving experience.
