How does the all-wheel steering system in the Audi A7 work?

I have read about Audi’s all-wheel steering system in the A7 and I am wondering how it actually functions. Can you explain the technology behind it and how it affects the car’s handling and performance?

The all-wheel steering system in the Audi A7 uses a combination of electronic sensors, actuators, and control units to optimize steering performance. The rear wheels can turn slightly in the same or opposite direction as the front wheels, depending on the speed and driving situation. This improves stability and handling, especially at high speeds.

The all-wheel steering system in the Audi A7 also allows for a smaller turning radius at low speeds, making it easier to maneuver in tight spaces. It also helps with parking and parallel parking, as the rear wheels can turn in the opposite direction of the front wheels to reduce the turning circle.
