How does the all-wheel drive system on the Audi A5 work?

I've heard that the Audi A5 has an impressive all-wheel drive system, but I'm not sure exactly how it works. Can someone explain it to me?

The Audi A5 uses a Quattro all-wheel drive system, which means it sends power to all four wheels simultaneously. This allows for better traction and handling in all types of road conditions.

Unlike other all-wheel drive systems that only kick in when needed, the Audi A5's Quattro system is always active. This means better control and stability at all times.

The Quattro all-wheel drive system on the Audi A5 monitors wheel slip and redirects power to the wheels with the most traction, giving you better handling and control on any road surface.
