What is the difference between Audi A8's Dynamic All-Wheel Steering and Rear Axle Steering?

I'm interested in purchasing an Audi A8 and noticed that it comes with two different steering options: Dynamic All-Wheel Steering and Rear Axle Steering. I'm not familiar with these technologies and would like to know their differences and which one would be better suited for my driving needs.

Dynamic All-Wheel Steering is a system that uses electronic steering actuators to adjust the steering response based on your speed and driving conditions. It provides more stable handling at high speeds and tighter turning radius at lower speeds. On the other hand, Rear Axle Steering is a separate system that physically turns the rear wheels in the opposite direction of the front wheels at low speeds to improve maneuverability and in the same direction at high speeds for better stability. It ultimately comes down to personal preference and driving style, but if you're someone who values agility and precision in driving, go for Dynamic All-Wheel Steering.

Dynamic All-Wheel Steering and Rear Axle Steering both offer significant benefits in terms of handling and stability. However, keep in mind that they are not interchangeable - you can only choose one for your Audi A8. If you prioritize comfort and improved handling at high speeds, go for Dynamic All-Wheel Steering. But if you often navigate through tight urban areas or have trouble parking, Rear Axle Steering would be more suitable.
