The climate in Hungary is really not quite the same as in Stuttgart...
I honestly don't know. We do get to subzero temperatures relatively easy in winter in Hungary, it's quite a different climate from Greece and Italy.

(I took Budapest, for the sake of generality, from [1] it is clear that there are significant variations in Hungary)
You can see that the mean temperatures from April to October are about 2 degrees higher in Budapest than in Stuttgart, which is really significant. To give you an idea, that's a lot closer to Avignon (France) [2], which is a Mediterranean climate, than to Stuttgart which is considered oceanic.
I also remember people saying that they could get 2 harvests of figs a year in Moravia (CZ), which you will not get in Germany. Moravia is not Hungary, but it's getting there, climate-wise, and it illustrates nicely the difference a few degrees (mean) make.
