How does the Audi 80's quattro system improve driving performance?

I've heard that the Audi 80 has a quattro all-wheel drive system, but I don't understand how that affects the car's handling and performance. Can someone explain it to me and how it's different from other all-wheel drive systems?

The quattro system on the Audi 80 distributes power evenly among all four wheels, providing superior grip and traction for improved performance and handling. This allows for better control and stability, especially in adverse driving conditions such as rain or snow.
