Sure it has been mentioned somewhere, but front subframe is Fiat Tipo based so shared with Tipo, Alfa 155 etc. Even the Multipla has a slightly modified version for the raised floor.
Rear subframe the same.
Front suspension is the same as the 155 V6.
16v turbo engine is almost identical (a few changes here and there) to the Alfa 155 Q4
Etc... Fiat and Alfa definitely raiding the parts bin. It's almost like when Fiat acquired Alfa and Lancia, they thought hmmm, wonder what I can fit that 16v Lancia lump to!!
