How to maximize fuel efficiency in an Audi A8?

I recently purchased an Audi A8 and I'm wondering how I can improve its fuel efficiency. Any tips or tricks?

One way to maximize fuel efficiency in your Audi A8 is to make sure your tires are properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%

Another tip is to avoid idling your car for extended periods of time. This not only wastes fuel but also causes unnecessary wear and tear on your engine. If you anticipate being stopped for more than a minute, it's better to turn off your engine.

You can also check your air filter regularly and replace it if it's dirty. A clogged air filter can decrease fuel efficiency and also impact the performance of your engine.
