Why is my Audi A8 experiencing poor fuel economy?

I've noticed that my fuel efficiency has decreased significantly in my Audi A8. What could be causing this issue and how can I improve it?

Max, one reason for poor fuel economy in your Audi A8 could be a clogged air filter. It's important to regularly check and replace your air filter to improve fuel efficiency. Another potential reason could be underinflated tires, so make sure to check your tire pressure regularly. Additionally, your driving habits can greatly impact fuel economy. Try to avoid aggressive acceleration and braking, and use cruise control when possible. Hope this helps!
