How does Audi's all-wheel steering system work in the A6?

I'm interested in understanding how Audi's all-wheel steering system works in their A6 model. Specifically, I want to know how it differs from traditional steering systems and what benefits it provides for drivers.

Audi's all-wheel steering system uses a combination of mechanical, hydraulic, and electronic components. It allows the rear wheels to turn in the opposite direction of the front wheels at low speeds, improving maneuverability and making tight turns easier. At higher speeds, the rear wheels turn in the same direction as the front wheels, providing more stability and control.

According to Audi, their all-wheel steering system provides better handling and agility, as well as improved safety. By allowing the rear wheels to turn, the car can respond more quickly and smoothly to steering inputs and maintain better stability in emergency situations. Overall, it enhances the driving experience and increases driver confidence on the road.
