What is the quattro all-wheel drive system in the Audi A7 and how does it improve handling?

I'm interested in the technology behind the Audi A7's handling capabilities. I've heard that the quattro all-wheel drive system is a major factor, but I don't fully understand how it works. Can anyone explain this in more detail?

The quattro all-wheel drive system is a key feature of the Audi A7 that sets it apart from other luxury cars. Essentially, it distributes power to all four wheels instead of just the front or rear, providing better traction and handling in any weather condition. My personal advice is to take the A7 for a spin on a wet or slippery road to truly feel the difference.
