What are the different driving modes available in the Audi A4?

I would like to know about the various driving modes offered in the Audi A4 and how they affect the driving experience.

The driving modes available in the Audi A4 are Comfort, Auto and Dynamic. These modes adjust the steering, suspension, and transmission to optimize the car's performance and driving comfort. When driving in Comfort mode, the steering is lighter and the suspension is more supple, providing a smoother ride. Auto mode allows the car to automatically adjust the settings based on driving conditions. Dynamic mode offers a sportier driving experience with more responsive steering and stiffer suspension.
