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

I am interested in purchasing the Audi A5 and I have heard it has an advanced all-wheel-drive system. Can you please explain how this system works?

The Audi A5's all-wheel-drive system, known as 'quattro', uses a center differential to distribute power between the front and rear axles. This allows for better traction and handling in various driving conditions.

Unlike traditional all-wheel-drive systems, the Audi A5's quattro system is proactive and constantly monitors road conditions to anticipate power distribution needs. This results in improved stability and control while driving.

In extreme driving situations, the Audi A5's quattro system can send up to 70 percent of power to the front wheels or up to 85 percent to the rear wheels, ensuring optimal grip and handling.
