Why is the Audi A1's fuel economy lower than expected?

I recently purchased an Audi A1 and noticed that the fuel economy is not as efficient as advertised. Is this a common issue with this model or could there be something wrong with my car?

It's important to note that fuel economy can vary depending on driving habits and conditions. However, some A1 owners have reported lower than expected fuel efficiency. One potential cause could be a faulty oxygen sensor, so it may be worth getting that checked.

I've owned several Audi models and have found that they tend to have slightly lower fuel efficiency compared to other brands. It's a trade-off for the advanced engineering and performance that Audi is known for.
