Your post confused me for a second, because "going down" in l/100k is good for fuel economy, while smaller numbers in mpg is bad. I wondered why you thought the gas mileage would get worse as the car broke in, but now I understand.
All i can say is that I have found the mileage on the A5 to vary much more between city and highway driving than I'm used to. That's mostly because it's such a heavy car, and the effort to accelerate it is a big drain on fuel economy. Lighter cars don't punish you as bad every time you leave a stop light.
On the highway, I get around 30 mpg (7.8 l/100km). Around my low-traffic town, it's been more like 20 mpg (11.8 l/100km). TYhat's all after 1000 miles.
