What is the difference between the Audi A6 Sportback and A6 Sedan?

I'm considering buying an Audi A6 and I'm wondering what the main differences are between the Sportback and Sedan options. Are there any performance or design variations that I should be aware of?

The main difference between the A6 Sportback and Sedan is their body styles. The Sportback has a more sleek and sporty look, while the Sedan has a traditional four-door design.

In terms of performance, the A6 Sportback and Sedan are nearly identical. They both offer the same engine options and have similar handling and driving dynamics.
