How does the Audi A5's Quattro system help with handling in various driving conditions?

I've heard that the Audi A5 has a Quattro all-wheel drive system, but I'm not sure how it actually improves handling. Can you provide more information on how it works and what benefits it offers in different driving situations?

The Quattro system in the Audi A5 actively monitors driving conditions and distributes power between the front and rear wheels as needed. This improves traction and stability, making it easier to handle the car in rain, snow, or slippery roads.
