How does the Audi A5's quattro system provide optimal traction and stability?

I've heard that the Audi A5's quattro all-wheel drive system is one of the best in the market. Can you explain how it works to provide such impressive traction and stability on the road? And how does it compare to other all-wheel drive systems?

The quattro all-wheel drive system in the Audi A5 uses a unique center differential to distribute power between the front and rear axles, providing improved handling and stability on all types of terrain. In comparison to other all-wheel drive systems, the quattro system allows for efficient distribution of torque and can adapt to changing road conditions for optimal performance.
