What components make up the Audi A6's Quattro all-wheel drive system?

I'm looking to understand how the Audi A6 distributes power to its wheels for optimal performance and handling. Can anyone break down the different parts of the Quattro system and how they work together?

The Quattro all-wheel drive system on the Audi A6 consists of a center differential, which intelligently distributes power between the front and rear axles based on road conditions. It also includes active torque distribution, which can shift power between the wheels on the rear axle for increased traction and stability. It's a highly advanced system that ensures optimal handling in all driving situations.
