How can the Audi A8 improve its fuel efficiency?

I have a new Audi A8 and I am concerned about its fuel efficiency. What can I do to optimize my car's fuel economy?

Regularly maintain your car, make sure the engine oil is changed at regular intervals and the tire pressure is checked every month.

Try to avoid idling your car for too long, as it can consume a lot of fuel. Instead, turn off your engine if you are waiting for more than a minute.

Carpool whenever possible and plan your trips efficiently to avoid unnecessary driving. This can significantly reduce your fuel consumption.
