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

I have been researching luxury cars and found that the Audi A5 has a lower fuel efficiency compared to other models in its class. Can anyone explain why this may be?

The Audi A5 is equipped with a more powerful engine, resulting in a lower fuel efficiency compared to other luxury cars. Consider alternative fuel-efficient models if this is a major concern.

The A5's aerodynamic design and high-performance tires may contribute to its lower fuel efficiency. Regularly maintaining and replacing these tires can help improve the car's efficiency.

Luxury cars often prioritize power and speed over fuel efficiency. The Audi A5 may have a lower fuel efficiency but it offers better acceleration and handling.
