Why is my Audi A7's fuel economy lower than expected?

I've noticed that my Audi A7's fuel economy is not as efficient as it used to be. What could be causing this and how can I improve it?

There could be a few reasons for this. One potential cause is that your tires are not properly inflated. This can significantly impact your fuel efficiency. Make sure to regularly check your tire pressure and adjust accordingly.

Another possible reason is that your air filter is dirty. A dirty air filter can restrict airflow to your engine, causing it to use more fuel. Check your air filter and replace it if necessary.

It's also important to consider your driving habits. Aggressive driving, such as speeding and constant acceleration and braking, can decrease fuel efficiency. Try to drive more smoothly and steadily.
