How does the Audi A5 compare with other luxury vehicles in terms of fuel efficiency?

I'm considering purchasing an Audi A5 but am concerned about the long-term costs of owning a luxury vehicle. Can anyone provide insights into the fuel efficiency of the A5 and how it stacks up against other luxury cars in its class?

Based on my research and personal experience, the Audi A5 actually has very good fuel efficiency for a luxury vehicle. It typically gets around 27-30 miles per gallon on the highway, which is similar to other cars in its class such as the BMW 4 Series and Mercedes C-Class.
