How does the all-wheel steering system work in the Audi A3?

I'm interested in knowing more about the all-wheel steering system implemented in the Audi A3. How does this system improve handling and overall driving experience?

The Audi A3's all-wheel steering system uses electronic controls to adjust the angle of the rear wheels in relation to the front wheels, allowing for improved stability and agility in both high and low speed driving.

With all-wheel steering, the Audi A3 can achieve a smaller turning radius and better maneuverability, especially when parking or navigating tight corners.
