Why is my Kia Niro's fuel efficiency lower than expected?

I recently purchased a Kia Niro and I noticed that the fuel efficiency is not as high as advertised. I expected to get around 50 mpg, but I am only getting around 40 mpg. Is there anything I can do to improve the fuel efficiency?

It is common for a car's fuel efficiency to be lower during the first few months of driving as the engine is still breaking in. Give it some time and you should see improvements.

Make sure you are driving efficiently by avoiding sudden accelerations and braking. Also, keeping your tires properly inflated can make a big difference in fuel efficiency.

Consider changing your driving habits to be more eco-friendly. This includes using cruise control, avoiding idling, and planning your routes to minimize stop-and-go traffic.
