What is the purpose of the 'quattro' system in an Audi 80?

Can anyone explain the technical functioning and benefits of the 'quattro' four-wheel drive system in an Audi 80?

The 'quattro' system in an Audi 80 is designed to distribute power evenly to all four wheels, providing better traction and stability in various driving conditions.

By constantly monitoring road conditions and sending power to the wheels with the most grip, the 'quattro' system can greatly improve handling and performance in wet or slippery conditions.

Additionally, the 'quattro' system can help improve fuel efficiency by reducing wheel spin and maximizing power transfer to the wheels, allowing for a smoother and more efficient drive.
