Why is the Kia Niro hybrid's fuel efficiency lower in colder weather?

I've noticed that my Kia Niro hybrid's fuel efficiency decreases during the winter months. Is this a common issue with hybrids? Is there anything I can do to maintain better fuel efficiency in colder weather?

In general, colder weather causes a decrease in fuel efficiency for all vehicles, not just hybrids. This is due to the fact that colder temperatures require the engine to work harder to maintain the same level of performance.

To help improve your fuel efficiency in colder weather, it's important to keep your Kia Niro hybrid properly maintained. This includes making sure your tires are properly inflated, your engine is properly tuned, and your air filters are clean.

You may also consider using a fuel additive specifically designed for cold weather, which can help improve the performance of your hybrid's engine and therefore improve fuel efficiency.
