What are the differences between the Audi A4 Sedan and Avant models?

I am looking to purchase an Audi A4, but I am not sure whether to go for the sedan or the avant model. Can someone explain the technical differences between the two?

The main difference between the Audi A4 sedan and avant models is the body shape. The sedan has a traditional four-door sedan design, while the avant is a station wagon with a more spacious cargo area. It ultimately comes down to personal preference and whether you prioritize style or practicality.
