Why is my Kia Niro's fuel efficiency not as advertised?

I recently purchased a Kia Niro and was promised great fuel efficiency. However, I am not seeing those numbers in real life. What could be the issue?

Firstly, make sure you are driving the car efficiently. Avoid sudden acceleration and braking, and maintain a consistent speed. Also, consider the type of roads you are driving on. Highways tend to have better fuel efficiency compared to city driving.

Another factor to consider is your tire pressure. Under-inflated tires can increase fuel consumption. Check your tires and make sure they are properly inflated.

You may also want to get your car checked by a mechanic. A faulty oxygen sensor or other engine issues can significantly affect fuel efficiency. Don't hesitate to bring it in for a diagnostic.
