Why is my Kia Niro not getting the advertised gas mileage?

I recently purchased a Kia Niro and have noticed that I am not getting the advertised gas mileage. I was expecting it to be more fuel efficient. What could be causing this and how can I improve the gas mileage?

It is important to keep in mind that the advertised gas mileage is based on ideal driving conditions. In reality, various factors such as weather, road conditions, and driving habits can affect your gas mileage.

Have you tried using cruise control on the highway? This can help improve your gas mileage by maintaining a consistent speed.

Another thing to consider is your tire pressure. Make sure your tires are properly inflated as under-inflated tires can decrease gas mileage.

I would also recommend avoiding unnecessary idling and speeding. These can significantly decrease fuel efficiency.
