How does the Audi A5's all-wheel drive system improve handling and performance on different road conditions?

I am interested in the Audi A5 and its Quattro all-wheel drive system. However, I am not very familiar with how this system works and how it benefits the performance of the car. I would like to know more about how this system functions and how it helps with handling and traction on different road surfaces.

The Audi A5's Quattro all-wheel drive system uses a center differential and electronic torque vectoring to distribute power to each wheel based on traction needs, effectively improving handling and stability on various road surfaces.
