What is the purpose of the Sport mode in the BMW 2 Series?

I noticed a Sport mode option in my BMW 2 Series but I'm not sure what it does. Can you explain its purpose and when I should use it?

The Sport mode in your BMW 2 Series is designed to enhance your driving experience by adjusting the car's performance to a more dynamic setting. It adjusts the throttle response, transmission, and steering to be more responsive and provide a more engaging drive.

You should use the Sport mode when you want to have a more spirited drive, such as on a winding road or when merging onto the highway. It can also improve your fuel efficiency by optimizing the car's performance.
