What is the Audi R8's Quattro system and how does it work?

I am curious about the technical specifications of the Audi R8's all-wheel drive system. I have heard it is called the "quattro" system, but I am unsure how it functions and what makes it unique. Can you provide an explanation?

The Audi R8's quattro system is a permanent all-wheel drive system that distributes power between the front and rear axles. It uses a self-locking center differential to transfer power to the wheels with the most grip. This provides superior traction and handling, especially in inclement weather.

Think of the Audi R8's quattro system as an intelligent power distribution system. It constantly monitors the road conditions and power demand, and adjusts traction accordingly. This not only improves performance, but also enhances safety for the driver and passengers.
