What causes poor fuel economy in Audi vehicles?

I recently bought an Audi and I have noticed that it doesn't have great fuel efficiency. I want to know what factors could be causing this issue so I can address them and improve my car's fuel economy.

One possible reason for poor fuel economy in Audi vehicles is excessive weight. If you have been carrying unnecessary items in your car or have installed heavy aftermarket parts, it can significantly decrease the car's fuel efficiency. Try removing any excess weight to see if it improves your car's mileage.

Another common culprit for poor fuel economy in Audis is dirty or clogged air filters. A dirty air filter restricts air flow to the engine, making it work harder and use more fuel. Check and replace your air filter regularly to improve your car's fuel efficiency.
