Why does the Audi A5 have a lower fuel efficiency compared to some other luxury cars?

I've noticed that the Audi A5 has a slightly lower fuel efficiency compared to other luxury car models in its class. Is there a specific reason for this? Can it be improved?

The Audi A5 is known for its powerful engine and advanced technology features, which can consume more fuel than other luxury cars. However, there are ways to improve fuel efficiency, such as using the Eco mode and regular maintenance.

The A5's aerodynamic design and heavy weight may also contribute to its lower fuel efficiency compared to other luxury cars. To improve it, make sure your tires are properly inflated and use a fuel additive to increase efficiency.

In addition, using premium fuel can also affect the A5's fuel efficiency. Consider using a higher octane fuel to get the most out of your car's performance and fuel economy.
