How does the active rear spoiler on the Audi R8 work?

I've heard that the Audi R8 has an active rear spoiler, but I'm not sure how it functions. Can you explain its purpose and operation?

The active rear spoiler on the Audi R8 is designed to improve the car's aerodynamics and stability at high speeds. It automatically deploys when the car reaches a certain speed, and adjusts its angle based on various factors such as speed and driving mode.

The active rear spoiler on the Audi R8 also serves as a visual cue for the car's performance. When it deploys, it creates a more aggressive and sporty appearance, letting others know that this car means business.

Not only does the active rear spoiler on the Audi R8 improve performance and aesthetics, it also functions as an airbrake. When you hit the brakes hard at high speeds, the spoiler will tilt to a more horizontal position, creating drag and helping the car slow down more quickly.
