How can I improve my Audi A6's fuel efficiency?

I recently bought a new Audi A6 and I love its performance, but I've noticed that it's not as fuel efficient as I expected. Is there anything I can do to improve its fuel efficiency?

One easy way to improve your Audi A6's fuel efficiency is to make sure your tires are properly inflated. Under-inflated tires require more energy to turn, which can result in higher fuel consumption. Check your tire pressure regularly and keep them inflated to the manufacturer's recommended level.

Another way to improve fuel efficiency is to minimize your use of the air conditioning. While it's refreshing in hot weather, AC can significantly impact your fuel economy as it requires the engine to work harder. Try using it sparingly and using the car's fan instead.
