What is the best way to increase fuel efficiency in an Audi A7?

I recently purchased an Audi A7 and I'm trying to find ways to improve its fuel efficiency. Can anyone provide some tips or tricks?

One effective way to increase fuel efficiency in an Audi A7 is to regularly maintain and service your vehicle. This includes keeping up with oil changes and ensuring your tires are properly inflated.

Another tip is to avoid idling your car for long periods of time. This wastes gas and can decrease fuel efficiency. Also, try to avoid sudden acceleration and harsh braking, as these can also use up more fuel.

You can also consider installing a more efficient air filter in your Audi A7. This can help improve air flow and, in turn, increase fuel efficiency.
