How does the Audi R8's AWD system distribute torque?

I've heard the R8 has an advanced AWD system, but I'm curious about how it actually works. Can anyone explain how torque is distributed between the front and rear wheels?

The Audi R8 utilizes a Quattro AWD system which uses a center differential to distribute torque between the front and rear axles in a 40:60 split. This allows for better handling and traction in all weather conditions.

The R8's AWD system also has the ability to send up to 100% of the torque to either the front or rear wheels when needed, providing enhanced performance and stability on different types of terrain.
