What is the difference between Audi's adaptive air suspension and dynamic steering?

I am looking to purchase an Audi A8 and I noticed that these two features are often grouped together in packages. Can someone explain the difference between them and if they are worth the investment?

The adaptive air suspension allows for customizing the ride height and firmness of the A8, while dynamic steering alters the steering ratio and weight for better handling and stability. Whether they are worth it depends on your preferences and driving style. Test drive both with and without these features to see if you notice a significant difference.

Adaptive air suspension is better for comfort and uneven road surfaces, while dynamic steering is better for performance and sharper turns. If your priority is a smooth ride, go for the air suspension. If you want a more dynamic and responsive driving experience, go for the dynamic steering.

In my opinion, both features are worth it for a luxury vehicle like the A8. The adaptive air suspension provides a comfortable ride, while dynamic steering adds a sporty element to your driving experience. Plus, it's always nice to have extra features that can make a difference in certain driving conditions.
