Fiat has taken full ownership of Chrysler, and the combined entity will be called Fiat Chrysler Automobiles (FCA), and will be headquartered (for tax purposes) in the UK, not Italy. With that, the "Big 3" are now the "Big 2", as GM and Ford are the only remaining American owned major auto makers. (Sorry Tesla, you don't count yet, come back when you make over 100,000 cars/year)
I see some bruised feelings all around. Auburn Hills is once again second fiddle. Italy loses Fiat's corporate registration. And the "A" in FCA lost its cross bar for some reason.
