How does the R8's all-wheel drive system work?

I'm interested in knowing more about the Audi R8's performance capabilities and was wondering how it's all-wheel drive system differs from other cars. Does it have any unique features or technologies?

The Audi R8 uses a permanent all-wheel drive system, which means power is constantly distributed to all four wheels. Additionally, it also has a rear-biased torque split, meaning that the majority of power is sent to the rear wheels for a more sports car-like feel and handling.

The R8's all-wheel drive system also features torque vectoring, which allows for power distribution to individual wheels based on driving conditions. This helps improve traction and handling, especially in corners and on slippery roads.

One of the most unique features of the R8's all-wheel drive system is the optional variable torque split, which allows the driver to adjust the power distribution between the front and rear wheels. This can be useful for optimizing performance or adapting to different road conditions.
