How does the Audi A7's Sportback feature contribute to its aerodynamics?

I read on the Audi website that the A7 has a Sportback feature, and I've heard that this contributes to its aerodynamics. How exactly does this feature work and what benefits does it bring to the car? Thanks in advance!

The Sportback feature on the Audi A7 is designed to optimize the car's aerodynamics. By extending the roofline and sloping it towards the rear, it creates a smoother airflow over the car, reducing drag and contributing to better fuel efficiency. It also gives the car a more sleek and sporty look.

The Sportback feature on the Audi A7 is not just for looks - it also serves a functional purpose. By optimizing the car's aerodynamics, it improves its overall performance and handling. Plus, it creates a quieter cabin for a more enjoyable driving experience.
