Why is the BMW X3's fuel economy lower than expected?

I recently purchased a BMW X3 and noticed that the fuel economy is not as advertised. What could be causing this and is there anything I can do to improve it?

There are a few possible reasons for lower fuel economy in your BMW X3. One common issue is overinflated tires, which can significantly affect your gas mileage. Make sure to check your tire pressure regularly and adjust it as needed.

Another factor that can affect fuel economy is aggressive driving habits. If you tend to accelerate quickly and brake hard, you may be using more fuel than necessary. Try to drive more smoothly and maintain a consistent speed to improve your gas mileage.
