Why does the Audi A6 have a lower MPG compared to other luxury sedans?

I've noticed that the mpg for the Audi A6 is lower compared to other luxury sedans in its class. Can you explain the reason behind this?

The Audi A6 is known for its powerful engine, which often requires more fuel to operate. This may be the primary reason for its lower mpg compared to other luxury sedans.

Another factor could be the weight of the Audi A6. As a larger and more spacious sedan, it may weigh more and require more fuel to operate efficiently.

It's also worth considering that Audi prioritizes performance and technology in their vehicles, which can also impact fuel efficiency. Other luxury sedans may prioritize efficiency over performance.
