How do the aerodynamics of the Audi R8 improve its performance?

I have heard that the Audi R8 has excellent handling and acceleration. How does its design and aerodynamics contribute to this?

The Audi R8 utilizes a race-inspired aerodynamic design, including a flat underbody and large rear diffuser, to create downforce and reduce drag. This allows for improved stability and increased top speeds.

In addition to its aerodynamic design, the R8 also has a mid-mounted engine and advanced Quattro all-wheel drive system, providing better weight distribution and traction for improved handling and acceleration.
