How does the 'quattro' system in the Audi A3 work?

I've heard about the 'quattro' system in the Audi A3, but I'm not fully sure how it works. Can someone explain the technology behind it?

The 'quattro' system in the Audi A3 is a permanent all-wheel drive system that distributes power evenly to all four wheels, providing better traction and grip on the road.

It basically uses sensors to monitor the road conditions and then sends power to the wheels that need it the most. This results in better handling and control, especially in slippery or uneven road conditions.
