I have an 09, so the comparison may not be valid, but even in the city, I get about 15l/100 km. I was doing better than that until the software "upgrade". Now the mdx shifts at higher points, so uses more fuel.
One thing for me that made a big difference was to turn the AC off. When I first got the car, it was sucking gas in the winter. The dealer told me to make sure to turn off the AC. I gained quite a bit by doing that. On the 09, in auto mode, you hit the AC button. The screen reads AC off. The default is to have it on so that the heated air is drier.
