Why is the Kia Niro's fuel economy not as good as advertised?

I recently purchased a Kia Niro and was surprised to find that the fuel economy is much lower than the advertised numbers. What could be causing this discrepancy?

It's possible that your driving habits and conditions are different from those used for the advertised fuel economy ratings. Try adjusting your driving style and see if it improves your fuel economy.

Another possible reason could be that the car is still new and has not yet gone through its break-in period. Give it some more time and see if the fuel economy improves.

Make sure you are using the recommended grade of fuel for your Kia Niro. Using lower quality fuel can result in lower fuel economy.
