What is the fuel economy of the Audi A7 and how does it compare to other luxury sedans?

I'm considering purchasing an Audi A7 but I want to make sure I am getting good fuel efficiency. Can someone provide details on the A7's fuel economy and how it stacks up against other luxury sedans in its class?

According to the EPA, the Audi A7 gets an estimated 22 mpg in the city and 29 mpg on the highway. This is comparable to other luxury sedans in its class, such as the BMW 5 series and Mercedes-Benz E-Class.
