How does the quattro all-wheel-drive system work on the Audi A3?

I've heard great things about the quattro all-wheel-drive system on the Audi A3. Can you explain how it works and why it's better than other AWD systems?

The quattro AWD system on the Audi A3 uses a self-locking center differential and can distribute up to 100% of the power to either the front or rear axle, depending on where it's needed most. This allows for better traction and handling, especially in inclement weather.

Compared to traditional AWD systems, the quattro on the Audi A3 is more proactive and can predict where power is needed instead of just reacting to wheel slip. This results in better overall performance and stability on varying road conditions.

With the quattro AWD system on the Audi A3, power is constantly being distributed between the front and rear axles, creating a more balanced and responsive driving experience. It also helps with cornering and handling at high speeds.
