How is the Audi e-Tron designed for maximum aerodynamics?

I'm looking for details on the design elements specifically focused on reducing air resistance, improving efficiency, and increasing range for the e-Tron.

The Audi e-Tron features a sleek exterior design that has been optimized for aerodynamics, with a drag coefficient of just 0.27. This is achieved through features such as a virtual exterior mirrors, aerodynamic wheels, and an underbody cover that reduces drag and turbulence.

In addition to its aerodynamic exterior, the e-Tron also utilizes air suspension that automatically lowers the vehicle at higher speeds to reduce drag. This allows for a more efficient and smoother ride, while also contributing to improved range.
