How does the Audi A7 achieve such efficient aerodynamics?

I have heard about the Audi A7's sleek design and advanced technology, but I am curious to know more about how it manages to be so aerodynamically efficient. Can you explain the specific features and techniques used to achieve this?

The Audi A7 utilizes a combination of its streamlined body shape, active aerodynamics, and aerodynamic components such as the air intakes, spoilers, and diffusers to reduce drag and enhance airflow. It also has adjustable suspension and a flat underbody for improved handling and stability at high speeds.
