What are the key differences between the Audi A4 and the A4 Avant?

I'm considering purchasing an Audi A4 but would like to know the main differences between the standard sedan and the A4 Avant model. Any notable differences in performance, features, and price?

The main difference between the Audi A4 and the A4 Avant is the body style. The A4 Avant is a wagon-style vehicle, offering more cargo space and potentially better handling on rougher terrain. Additionally, the A4 Avant typically comes with a slightly higher price tag due to its added features and capabilities.
