What is the Quattro drivetrain in the Audi R8 and how does it improve performance?

I've heard that the Audi R8 has a unique Quattro drivetrain. Can you explain what this means and how it affects the car's performance?

The Quattro drivetrain in the Audi R8 is an advanced all-wheel drive system that distributes power to all four wheels for optimal traction and stability. This not only ensures better handling and cornering, but also allows for a more powerful and efficient acceleration.
