How can I improve gas mileage in my Audi A7?

I've noticed that my Audi A7 isn't getting the gas mileage it used to. What are some ways I can improve it?

Make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage.

Avoid aggressive driving and excessive idling. Both of these can use up more fuel than necessary.

Consider using cruise control when driving on the highway. This can help maintain a consistent speed and improve gas mileage.
