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

I've heard that the Audi A7 has an all-wheel steering system, but I'm not exactly sure how it works. Can you explain it to me in more detail?

The all-wheel steering system on the Audi A7 uses a combination of rear steering and torque vectoring to improve handling and stability. This means that the rear wheels can turn in the opposite direction of the front wheels at low speeds, making the car more agile and easier to maneuver. At high speeds, the rear wheels turn in the same direction as the front wheels, creating a larger stable track width.

From personal experience, I can say that the all-wheel steering system on the Audi A7 is a game changer. Whether on winding roads or navigating tight city streets, the rear steering makes a noticeable difference in handling and makes the car feel more responsive and nimble.
