Disagree.
Sergio got the company in a very bad shape. High interest rates and not so great or very limited cash flow.
For example first dividends by FCA were paid in 2018. Gues when he/Sergio died?
Most developments were already firing under all cylinders under Sergio. A lot was killed or postponed by Manley and later PSA
Heck even relationship with ZF is spared because of Mike and Carlos. Under Sergio there were huge or at least hit plans for the 4th generation of ZF 8HP in both hybrid forms with early adopted being Maserati and Alfa Romeo.
I would put my hand in the fire and say that GME T6 was originally planned as P2.5 MHEV with ZF 8HP 4th gen as the integral part of it.
I may tell you which products, platforms and powertrains were killed by Manley and Tavares. I know more about Europe but I think that
@redriderbob can tell much more about the USA.
Don't forget that this GME only craze, limited powertrain chocies, BEV first launches and even BEV only products, are idea of Manley and even more ex PSA management. This is crazy what are they doing.
Don't forget all those fired people in US and Italy, especially on the engineering side.
If I'm not mistakes now 65% of they STLA patents are by ex PSA, they come from France.
Sergio on the other hand was very interested in growth of American and Italian workforce. Something which can't be said about Carlos.
