How to improve fuel efficiency in my Audi A8?

I recently noticed that my Audi A8 consumes a lot of fuel, even with its efficient engine. What steps can I take to improve its fuel efficiency?

One way to improve fuel efficiency is by regularly maintaining your vehicle. This includes keeping your tires inflated to the recommended pressure, getting oil changes and tune-ups at the suggested intervals, and replacing air filters when needed.

You can also try changing your driving habits. Avoid speeding and sudden accelerations, as these can greatly decrease your fuel efficiency. Plan your trips to minimize unnecessary driving and use cruise control on the highway to maintain a steady speed.
