How does the Audi A7's Quattro all-wheel drive system function?

I've heard that Audi's Quattro all-wheel drive system is one of the best on the market, but I'm not sure how it actually works. Can someone explain the technical details of this system and what sets it apart from others?

The Quattro system uses a center differential and torque vectoring technology to distribute power to all four wheels, providing improved traction, handling, and stability. While most AWD systems only respond when a wheel slips, Quattro is predictive and proactively sends power to the wheels with the most grip.

One of the main advantages of Quattro is that it can send up to 85% of the power to the rear wheels, giving the A7 a sportier feel while still maintaining stability and control. Plus, the system is constantly adjusting to changing road conditions, making it ideal for any type of weather or terrain.

In addition to its functional benefits, the Quattro system also adds to the overall driving experience of the A7. The balanced and precise handling allows for confident driving on twisty roads, while the extra traction and grip provide a sense of security in any driving situation.
