Why is the Kia Picanto's fuel economy worse than advertised?

I recently purchased a Kia Picanto and was disappointed to find that its fuel economy is not meeting the advertised numbers. Can anyone explain why this is happening?

Hi Steve, the advertised fuel economy numbers are determined in laboratory conditions and may not reflect real-world driving scenarios. Factors such as driving style, road conditions, and vehicle maintenance can greatly affect fuel consumption.

Hi Steve, it could be that your Kia Picanto is still in its break-in period. New cars tend to have poorer fuel economy until they have been driven for a while. Try keeping to a consistent speed and avoiding sudden accelerations to help improve your fuel efficiency.

Hi Steve, have you checked your tire pressure? Underinflated tires can reduce fuel economy by up to 3%. Make sure to regularly check and adjust the pressure according to your vehicle's recommended levels.
