What is Audi A3's Quattro system and how does it work?

I've heard of Audi's Quattro system, but I'm not sure what it is or how it works. Can someone explain it to me in simple terms?

The Audi A3's Quattro system is a proprietary all-wheel drive technology that allows for better handling and traction on all types of road conditions. It works by distributing power to each individual wheel as needed, providing improved stability and control while driving.

Simply put, the Quattro system in the Audi A3 utilizes a center differential to split power between the front and rear axles, and then uses additional technology to transfer power between the left and right wheels as needed. This results in enhanced grip and performance, especially in wet or slippery conditions.
