Why is the Audi A2's fuel efficiency lower than expected?

I recently purchased an Audi A2 and was expecting it to have great fuel efficiency based on its advertised specs. However, I'm noticing that it's not living up to those expectations. Why is this happening and what can I do to improve its fuel efficiency?

Samantha, fuel efficiency can vary depending on a few factors such as driving habits, maintenance, and road conditions. It's important to make sure you're following proper maintenance schedules for your Audi A2 to help improve fuel efficiency.
