Why is the fuel economy in my Audi A2 not meeting the EPA estimated ratings?

I purchased a used 2016 Audi A2 and noticed that the fuel economy is lower than what the EPA estimated. Is there any way to improve the fuel efficiency and achieve the estimated ratings?

According to Audi, the fuel economy in your car can be affected by various factors such as driving habits, terrain, and weather conditions. To improve your fuel efficiency, try driving at a moderate speed, avoiding quick accelerations and maintaining proper tire pressure.

One thing you can do to improve your fuel economy is to regularly service and maintain your car. This includes getting your oil changed, replacing air filters, and ensuring your engine is running smoothly. This can help your car run more efficiently and achieve better fuel ratings.
