What is the difference between the Audi A8's Quattro all-wheel drive system and other all-wheel drive systems?

I've heard that the Audi A8 has a unique all-wheel drive system called Quattro, but I'm not sure how it differs from other all-wheel drive systems on the market. Can you explain?

The Audi A8's Quattro all-wheel drive system uses a center differential to distribute power between the front and rear axles, allowing for more precise and efficient handling. And because the power is split evenly between the front and rear axles, the A8's Quattro system provides better traction and stability compared to other systems that may only send power to specific wheels.
