Why is my Kia Niro not getting the advertised fuel efficiency?

I recently purchased a Kia Niro and was attracted by the advertised fuel efficiency of 52 mpg. However, I have been getting only around 45 mpg. What could be the reason for this and how can I improve it?

It is important to note that the advertised fuel efficiency is based on ideal conditions and it may vary in real-world driving scenarios.

Some factors that can affect fuel efficiency include driving habits, road conditions, and weather.

You can try using the eco mode and avoiding aggressive acceleration and braking to improve your fuel efficiency.

Another tip is to keep your tires properly inflated and to regularly maintain your vehicle.
