What does the 'Sport' mode in my BMW 1 Series do?

I've noticed a 'Sport' mode button on my BMW 1 Series dashboard. What does it do and when should I use it?

The 'Sport' mode in your BMW 1 Series adjusts various settings in the car to provide a more dynamic driving experience. It increases engine response, improves throttle response, and changes the transmission shift points. You can use it when you want a more spirited driving experience or when driving on curvy roads.

Switching to 'Sport' mode also changes the suspension settings, making the car feel more agile and responsive. This can be useful when driving on bumpy roads or when you want a more engaging driving experience.

However, keep in mind that driving in 'Sport' mode can decrease your fuel efficiency. It's best to use it sparingly and switch back to the default mode for regular daily driving. It's also important to drive safely and responsibly, even in 'Sport' mode.
