How does the quattro AWD system in the Audi A3 work?

I've heard a lot about Audi's quattro all-wheel drive system, but I'm not sure how it actually functions. Can someone explain the mechanics of how it works in the A3?

The quattro system in the Audi A3 uses a center differential to distribute power between the front and rear axles. This allows for better grip and stability, especially in challenging road conditions.

It's important to note that the quattro system is not just meant for performance, but also for safety. By constantly monitoring the road and adjusting power distribution, it can help prevent skidding and improve handling in emergency situations.

While newer Audi A3 models use a electronically-controlled multi-plate clutch, some older versions may have a Torsen differential. Both systems work similarly to provide power to the wheels with the most traction.
