The factory is in Italy, As of now it is a small applicaton. I remember reading somewhere, and forgive me I cant remember the source, but they are looking to expand capacity at the plant as it seems that since Motori has become a fully owned FIAT subsidary they will be the prime source for diesel mills for all of FCA.
I do wonder what sort of supply constraints there will be seeing as Motori is supplying engines for the ghibli, GC and RAM 1500...
