What is the Quattro system on the Audi A7 and how does it work?

I've been hearing a lot about the Quattro system on the Audi A7, but I'm not sure what it's all about. Can someone explain what it is and how it differs from other all-wheel drive systems?

The Quattro system on the Audi A7 is a permanent all-wheel drive system that constantly monitors and adjusts power to each wheel for maximum traction and stability. It's known for its superior performance and handling, especially in adverse weather conditions.

Compared to other all-wheel drive systems, the Quattro system on the Audi A7 is more efficient and responsive due to its mechanical and electronic components working together seamlessly. This results in improved fuel economy and better handling on different road surfaces.
