How does Audi's Quattro all-wheel drive system work?

I have heard that Audi has a unique all-wheel drive system called Quattro. Can someone explain how it works and what makes it different from other all-wheel drive systems?

Audi's Quattro system uses a center differential to distribute power between the front and rear axles. This allows for better traction and handling on all types of roads.

Unlike traditional all-wheel drive systems, Quattro can proactively distribute power to the wheels with the most grip, rather than reactively when a wheel loses traction. This allows for improved performance and stability in all driving conditions.

Quattro also employs electronic control systems to monitor driving conditions and adjust power distribution accordingly. This creates a seamless transition between all-wheel drive and front-wheel drive to optimize performance and fuel efficiency.
