How does the Quattro all-wheel-drive system work in the Audi A4?

I'm considering buying an Audi A4 and I keep hearing about the Quattro all-wheel-drive system. How does it actually work and what are the benefits?

The Quattro system uses sensors to monitor the road conditions and automatically distributes power to the wheels with the most grip. This improves handling, traction, and overall performance, especially in adverse weather conditions.

I would highly recommend the Quattro all-wheel-drive system in the Audi A4. I have been driving one for years and it has never let me down, even in snowy and icy conditions.

The Quattro system also includes torque vectoring, which helps to improve cornering and stability. It distributes power to individual wheels for more precise handling and control.
