How to effectively increase fuel efficiency in a Volkswagen Arteon?

I recently purchased a Volkswagen Arteon and I've noticed that it's not as fuel-efficient as I was expecting. Is there anything I can do to improve its fuel efficiency without sacrificing performance?

Firstly, make sure your tires are properly inflated and aligned. This can greatly impact fuel efficiency.

Try driving at a consistent speed and avoid hard braking or accelerating. This can help improve fuel economy.

Regular maintenance such as oil changes and air filter replacements can also improve your Arteon's fuel efficiency.
