What does the 'Quattro' function do in the Audi 80?

I've heard that the Audi 80 has a 'Quattro' feature, but I'm not quite sure what it does. Can someone explain its purpose and if it's worth having?

The 'Quattro' function in the Audi 80 is a permanent all-wheel drive system that provides better handling and traction on different road surfaces. It distributes power to each wheel individually, enhancing stability and control. As for whether it's worth having, it depends on your driving needs and location.
