I believe Quattrofolio engine is based on a Ferrari design (block is shortened 8 cylinder) and that Ferrari engineers were deeply involved in the development process. Hard to imagine they'd be able to support the volume production but what plant produces them I don't know.
Have to say following the new products and corporate integration, I am very excited about FCA at this time. Marchionne is a wizard from my point of view.
The history is, at least as I know it, is that the V6 engine is essentially 6 of the 8 cylinders from the Ferrari California twin-turbo 3.9-litre V8 and a slightly smaller variation of the same twin turbo setup to account for the missing 2 cylinders. As for the design team, it's my understanding that the chief designer / project manager for the Georgio platform was previously the chief designer & project manager for the Ferrari FXXK track only version of the La Ferrari (and was involved in some way with the design of the La Ferrari as well, but what extent I'm unsure).
So the description that these are "Poor Man's Ferrari's" is not that far from the truth!
