How does the Audi A3's Quattro system improve performance?

I've heard about the Quattro system in Audi's, but I'm not sure exactly how it works or what benefits it provides. Can you explain?

The Quattro system in Audi vehicles is an all-wheel drive system that uses advanced technology to evenly distribute power to each wheel. This results in improved traction, control, and performance, especially in challenging road conditions.

One of the main advantages of the Quattro system is its ability to provide power and torque to the wheels with the most grip, allowing for better handling and stability. This is especially helpful when driving in wet, snowy, or icy conditions.

In addition to improved performance, the Quattro system also helps with fuel efficiency by only sending power to the wheels that need it. This can result in better gas mileage and lower overall cost of ownership.
