Why does my Kia Niro's fuel efficiency decrease in cold weather?

I've noticed that my Kia Niro's fuel efficiency decreases significantly during cold weather. Is this a problem with the car or is it a common issue with hybrid vehicles? Should I be concerned and is there anything I can do to improve the fuel efficiency in cold weather?

This is a common issue with most hybrid vehicles, not just the Kia Niro. Cold weather affects the battery's performance, resulting in decreased fuel efficiency.

I recommend parking your car in a heated garage or using an engine block heater during cold weather to improve fuel efficiency.

Regularly changing your car's air filter and ensuring proper tire pressure can also help improve fuel efficiency in cold weather.
