How does the Audi A7's all-wheel steering system enhance driving performance?

I've heard that the Audi A7 has all-wheel steering, but I'm not sure how it works. Can anyone explain its function and advantages?

The all-wheel steering system on the Audi A7 allows for enhanced handling and control while driving at high speeds. It also helps to reduce the turning radius, making it easier to maneuver in tight spaces. Overall, it provides a more dynamic driving experience.

With the all-wheel steering system, the rear wheels can turn in the same direction as the front wheels at higher speeds, providing better stability and cornering performance. At lower speeds, the rear wheels turn in the opposite direction, making parking and navigating through congested areas smoother.
