What is the Audi A5's Quattro System?

I've heard about the Audi A5's Quattro system, but I'm not sure exactly what it does or how it works. Can someone explain?

The Audi A5's Quattro system is an all-wheel drive system that is designed to improve traction and handling in all types of weather and road conditions. It utilizes a center differential to distribute power between the front and rear wheels, providing better balance and control. As a personal recommendation, I would highly recommend opting for this upgrade on your A5 model for an even more dynamic driving experience.
