How does the Audi A7's Quattro four-wheel drive system work?

I've heard that the Audi A7 has an advanced four-wheel drive system called Quattro. Can someone explain how this system works and what makes it unique?

Quattro is a permanent four-wheel drive system that continuously distributes power to each individual wheel based on the driving conditions. This allows for improved stability, traction, and handling, especially in challenging weather or road conditions.

The Quattro system uses a central differential to split the power between the front and rear axles, and then allocates the power between the left and right wheels as needed. This creates a balanced and responsive driving experience, even on slippery or uneven surfaces.
