How does the Audi A7 Quattro transmit power to all four wheels?

I am looking to purchase an Audi A7 Quattro but I am unsure about the power transmission system. Can someone provide more details on how the A7 Quattro manages to send power to all four wheels efficiently and effectively?

The Audi A7 Quattro uses a permanent all-wheel drive system called quattro, which constantly monitors road conditions and distributes power to the wheels that need it the most. This allows for better handling and traction on various types of terrain.
