How does the Audi A8's Quattro all-wheel drive system improve handling in various weather conditions?

I'm trying to understand the benefits of the Audi A8's Quattro all-wheel drive system in terms of handling and control. Can someone explain how this technology works and how it enhances the driving experience in different environments?

The Quattro all-wheel drive system in the Audi A8 uses a central differential to distribute power between the front and rear wheels. This allows for better traction and stability on different road surfaces, such as ice, snow, or wet pavement. As a result, the car has improved handling and control, especially in challenging weather conditions.
