How does the Audi A7's Quattro system work and what makes it different than other AWD systems?

I've heard that the Audi A7 has a unique AWD system called Quattro, but I'm not familiar with it. Can someone explain how it works and how it's different from other AWD systems on the market?

The Audi A7's Quattro system uses a center differential to distribute power between the front and rear axles, allowing for a balanced and controlled power delivery. Unlike other AWD systems, it also has the ability to distribute power between the left and right wheels, providing even more stability and control.
