Why is the fuel economy on my Audi A4 lower than expected?

I recently purchased a new Audi A4 and have noticed that the fuel economy is not as efficient as it was advertised. What could be causing this and how can I improve it?

The most common reason for lower fuel economy in the Audi A4 is underinflated tires. Make sure to regularly check your tire pressure and inflate them to the recommended levels.

Another factor that can affect fuel economy is driving habits. Avoid sudden acceleration and braking, and maintain a steady speed. This can greatly improve your fuel efficiency.

Check your air filter and replace if necessary. A clogged air filter can decrease fuel economy and overall engine performance.
