Why does the Audi A7 have a lower fuel efficiency compared to other cars in its class?

I am considering purchasing an Audi A7 but have noticed that it has a lower fuel efficiency rating compared to other cars in its class. Can anyone explain why this might be the case?

The Audi A7 has a larger engine size and more powerful performance than other cars in its class, which can result in a lower fuel efficiency.

The Audi A7 is designed for a more luxurious and powerful driving experience, which may prioritize performance over fuel efficiency.
