What is the difference between Audi's A7 Sportback and A7 sedan?

I'm looking to purchase a new Audi A7, but I'm confused about the difference between the Sportback and sedan models. Can you clarify for me?

The main difference between the A7 Sportback and sedan is the body style. The Sportback has a sleeker, more streamlined look, while the sedan has a more traditional, boxy design. Both models offer similar performance and features.

One major difference is the rear seating. The A7 Sportback has a more spacious and comfortable rear seat, while the sedan has a tighter, more compact rear seat. Depending on your needs, this may play a factor in your decision.
