How does the Audi R8 maintain such a low drag coefficient?

The Audi R8 has a drag coefficient of just 0.36, which is incredibly low for a high-performance sports car. I'm curious as to how Audi achieves such efficiency in their design and what specific features contribute to this low drag coefficient.

The Audi R8's aerodynamic design is largely due to its sleek, angular body shape and the use of lightweight materials like aluminum and carbon fiber. Additionally, the car has an active rear spoiler that automatically adjusts to reduce drag at high speeds.

Another factor contributing to the low drag coefficient of the Audi R8 is its aerodynamically optimized underbody, which helps to reduce air resistance and improve overall performance. This design feature is also seen in the car's large rear diffuser.

The shape and design of the Audi R8's side mirrors also play a role in minimizing drag. The mirrors are mounted on the doors instead of the A-pillars, which allows for smoother airflow around the car.
