Increasing Fuel Efficiency in Audi A5

I am looking to improve the fuel efficiency of my Audi A5. Are there any modifications or maintenance tasks I can do to improve it?

Regularly check and maintain tire pressure to improve gas mileage and reduce fuel consumption. You can also invest in low rolling resistance tires for better fuel efficiency.

Avoid excessive idling, as it wastes fuel and lowers fuel efficiency. Try to turn off the engine if you are going to be stopped for more than a minute.
