VM Motori is since end of 2013 100% owned by FCA.
Before it had 50% and the other 50% was owned by GM.
The Promaster F1C diesel engine is from FPT Industrial, that is part of CNH Industrial (Case New Holland industrial).
CNH Industrial is the result of a demerge from Fiat group that rook place in 2011/2012.
The same F1C engine is used in Mitsubishi Fuso Canter in U.S.A., known as 4P10 engine.
Since last year the F1C is not used in Fiat Ducato, replaced by a more powerful version of the smaller F1A engine (same family, but different injectors, EGR, turbocharger, ...). F1C is still used by IVECO (part of CNH Industrial) for the Daily, military vehicles (IVECO LMV and others) plus in stationary applications.
There is also a maritime version named S30.
