How does the Audi A7 maintain its aerodynamic design?

I've heard that the Audi A7 has an incredibly sleek and aerodynamic design, but what features does it have that make this possible? I'm looking for a deeper understanding of how this car achieves its impressive efficiency and performance.

The Audi A7's aerodynamic design is a result of careful engineering and attention to detail.

One of the key components of the Audi A7's aerodynamic design is its active rear spoiler, which adjusts to reduce drag and improve handling at higher speeds.
