How does the quattro system in the Audi A3 enhance its performance?

I've heard that the Audi A3 has a quattro system, but I'm not sure what it does. Can someone explain its function?

The quattro system in the Audi A3 is an all-wheel drive system that uses sensors and advanced technology to constantly monitor road conditions. This allows for optimal power allocation between all four wheels, resulting in better grip and handling in all driving situations.

The quattro system in the Audi A3 is a game changer. It improves the car's stability, handling, and grip, especially on slick roads. Trust me, it's worth every penny.

Having driven both front-wheel and all-wheel drive vehicles, I can say that the quattro system in the Audi A3 provides a noticeable difference in handling and traction, especially in inclement weather.
