How does the Audi A3's quattro system improve handling and traction?

I am curious about the specifics of Audi's famous quattro system and how it enhances the driving experience of the A3 model.

The quattro system in the Audi A3 provides power to all four wheels, allowing for better handling and control in various driving conditions. In particular, it improves traction on slippery roads or uneven terrains.

By utilizing sensors and electronic controls, the quattro system continuously monitors driving conditions and adjusts power distribution between the front and rear axles. This results in improved stability and cornering performance.
