What is the purpose of the Audi A1's drive select system?

I've noticed that some Audi A1 models are equipped with a drive select system. What is the feature's purpose and how does it work?

The drive select system in the Audi A1 allows the driver to choose between four different modes -comfort, auto, dynamic, and efficiency- to optimize the vehicle's performance and handling according to their preferences. For example, the comfort mode offers a smooth and balanced ride, while the dynamic mode provides a more sporty and responsive driving experience. It's a great feature for personalizing your driving experience.

The drive select system allows the Audi A1 to adjust its suspension, steering, and transmission characteristics to suit different driving situations and styles. This can enhance handling, performance, and efficiency. For example, in efficiency mode, the car will automatically adjust these components to maximize fuel efficiency. It's a great tool for optimizing your driving experience and getting the most out of your vehicle.
