What is the most efficient way to maintain a good fuel economy in my Audi A7?

I recently bought an Audi A7 and I noticed that its fuel consumption is not as efficient as advertised. What can I do to improve its fuel economy and save on fuel costs?

One of the most important factors in maintaining a good fuel economy in any vehicle is to ensure that your tires are properly inflated. Under-inflated tires can cause your car to use more fuel than necessary. Make sure to check your tire pressure regularly and adjust it according to the manufacturer's specifications.
