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

I'm in the market for a new car and I'm deciding between the Audi A4 and A4 Avant models. Can you help me understand the main distinctions between these two options?

The primary difference between the Audi A4 and A4 Avant lies in their body styles. The A4 is a sedan while the A4 Avant is a station wagon. This means the A4 Avant offers more cargo space, but the A4 may offer smoother handling and a more compact design.
