What is the Quattro four-wheel drive system in the Audi 80?

I've heard about the Quattro four-wheel drive system in Audi cars, but I'm not sure how it works. Can someone explain it to me?

The Quattro four-wheel drive system in the Audi 80 is a permanent all-wheel drive system that distributes power evenly between the front and rear axles. This provides increased traction and stability, especially in slippery conditions. It also offers superior handling and cornering performance.

The Quattro four-wheel drive system in the Audi 80 uses a Torsen center differential to send power to the axles with the most grip. This ensures that power is distributed efficiently and effectively, maximizing control and performance.
