What sets the Audi R8's Quattro system apart from other all-wheel-drive systems?

I've heard that the Quattro system in the Audi R8 is unique and fantastic, but I'm not sure how it differs from other all-wheel-drive systems. Can someone explain its features and advantages?

The Quattro system in the Audi R8 uses a combination of all-wheel drive and torque vectoring technology to distribute power to the wheels that need it most in real-time, resulting in better traction and handling.

Unlike some all-wheel-drive systems that have a 50/50 front/rear torque split, the Quattro system in the Audi R8 can vary the torque split depending on driving conditions, providing optimal performance in every situation.

The Quattro system in the Audi R8 is also able to transfer power between the left and right wheels, allowing for even better cornering and stability.
