How does the Audi A8's quattro permanent all-wheel drive system improve driving experience?

I am curious about the quattro permanent all-wheel drive system in the Audi A8. How does it work and what specific improvements does it offer compared to other all-wheel drive systems?

The quattro permanent all-wheel drive system in the Audi A8 distributes power to each wheel individually, enhancing the car's traction, stability, and handling. Unlike other all-wheel drive systems, it continuously monitors and adjusts torque distribution to ensure optimal performance in various driving conditions.
