How can I increase my Audi's fuel efficiency?

I recently bought a brand new Audi and I've noticed that it's not very fuel efficient. Is there anything I can do to improve its fuel efficiency?

Regularly maintain your Audi by getting tune-ups and oil changes. This will ensure that your engine is running at its best and can help improve fuel efficiency.

Consider changing your driving habits. Avoid sudden acceleration and braking, and try to maintain a steady speed while driving. This can help reduce the amount of fuel your Audi consumes.
