Why is the Audi A5's fuel efficiency lower than expected?

I recently purchased an Audi A5 and was impressed by its advertised fuel efficiency. However, after driving it for a few weeks, I've noticed that it's not living up to its promise. What could be causing this discrepancy in fuel efficiency?

Hello Samantha, have you checked your tire pressure recently? Under-inflated tires can decrease fuel efficiency. Make sure to regularly check and maintain proper tire pressure.

Hi Samantha, another factor that could be affecting your fuel efficiency is your driving habits. Do you tend to accelerate and brake aggressively? This can greatly decrease fuel efficiency. Try to drive more smoothly and see if that helps.
