How can I improve the fuel efficiency on my Audi A7?

I've noticed that my Audi A7 is not getting great gas mileage. Are there any tips or tricks I can use to improve its fuel efficiency?

First, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Also, try to avoid idling for long periods of time and combine errands into one trip to minimize driving. You can also use cruise control on the highway to help maintain a consistent speed. Lastly, consider getting a tune-up to ensure your engine is running efficiently.
