BTW, what I forgot to mention, I drive the 520dF10 (163hp/380Nm) and 530iE39 (231hp/300Nm). So the 530i would be far superior don't you think?
Well it's only mildly superior when you can drive at speeds that put you behind bars immediately and when you keep rpm +4000... All other conditions the 520d is better and feels like a superior engine (I don't compare the cars, since the F10 really obliterates the E39 of course!).
The 530i even frustrates by its lack of grunt under the 3000rpm. Oh yeah, average consumption 520d = 6,1l/100km and 530i=13l/100km. So, again, the 118d is way, way, way superior to the 116i.
