How to increase fuel efficiency in Audi A4?

I recently purchased an Audi A4 and noticed that the fuel efficiency is not as high as advertised. How can I improve the fuel efficiency and get the most out of my car's performance?

Regularly maintain your car by getting it serviced at authorized Audi service centers. This will ensure that the engine is running smoothly and efficiently.

Avoid aggressive driving and excessive acceleration as it can use up more fuel. Instead, maintain a steady speed and use cruise control when possible.
