How does the all-wheel steering system in the Audi A8 work?

I've heard that the Audi A8 has an all-wheel steering system that improves handling and stability. But how exactly does it work?

The all-wheel steering system in the Audi A8 is a complex electronic system that uses sensors and actuators to adjust the angle of the rear wheels. This allows the rear wheels to turn in the same direction as the front wheels at high speeds, improving stability and handling. It can also turn the rear wheels in the opposite direction at lower speeds, making the car more maneuverable in tight spaces.

The Audi A8's all-wheel steering system uses a hydraulic system to turn the rear wheels at different angles than the front wheels. This makes the car more stable and responsive to driver inputs at high speeds, while also improving maneuverability at low speeds.
