How does the quattro system in the Audi A4 improve handling and performance?

I've heard that the Audi A4 has a quattro system, but I'm not sure how it works and what benefits it offers. Can you provide some more information?

The quattro system in the Audi A4 distributes power to all wheels, providing better traction and stability in all road conditions. It works by constantly monitoring road conditions and delivering power to the wheels with the most grip. This results in improved handling and performance, especially in inclement weather or off-road driving.

Having driven both the front-wheel drive and quattro versions of the Audi A4, I can say with confidence that the quattro system makes a significant difference in handling and performance. The car feels more planted and responsive on the road, even in sharp turns and at high speeds.
