What is the difference between Audi R8's quattro and other all-wheel drive systems?

I've heard that the Audi R8 has a unique all-wheel drive system, but what sets it apart from other all-wheel drive systems in other cars? Can it be adjusted or customized at all?

The Audi R8's quattro system is designed to distribute power to each individual wheel for optimal traction and handling. Unlike other all-wheel drive systems, it can also vary torque to individual wheels for even better performance. It cannot be adjusted or customized, but it already delivers exceptional handling and control in various driving conditions.

The quattro system in the Audi R8 has a rear-biased torque split, meaning it prioritizes power to the rear wheels for a more dynamic and engaging driving experience. It also has a unique electronic limited-slip differential that can distribute torque between the rear wheels for even more precise handling. As for customization, the system can be set to different driving modes to adapt to various road conditions.
