What is the Quattro system in the Audi A5 and how does it work?

I've heard that the Audi A5 has a Quattro system but I'm not entirely sure what it is or how it works. Can someone explain it to me in simple terms?

The Quattro system in the Audi A5 is a permanent all-wheel drive system designed to provide better handling and traction in various road conditions. It works by constantly monitoring the grip of each wheel and distributing power accordingly.

In simple terms, the Quattro system distributes power to all four wheels, providing better stability and performance on wet or slippery roads. It's a great feature to have in the Audi A5, especially for those living in areas with varying weather conditions.
