What is the purpose of the Audi A3's Sport Mode?

I'm considering buying an Audi A3 and I noticed it has a Sport Mode. What is the purpose of this feature and how does it affect the car's driving experience?

Sport Mode is designed to enhance the driving dynamics of the Audi A3. It adjusts the car's transmission, steering, and suspension for a more responsive and dynamic driving experience on winding roads or on the track.

I've found that using Sport Mode on the Audi A3 can also improve fuel efficiency in certain situations. When driving at higher speeds, the car's computer will optimize gear changes to maximize efficiency and reduce fuel consumption.

In my experience, Sport Mode on the Audi A3 is best used when you want a more powerful and engaging driving experience. It increases throttle response and sharpens the car's handling, making it perfect for spirited driving on open roads.
