FCA’s goal from the May 2014 Investor Day: to have 95% of total volume from five platforms...
Mini: three cars, probably all Fiat
B-Wide: four cars, probably three Fiats (or two Fiats plus Chrysler 100) plus Jeep Renegade
Compact Wide (CUSW): Dart, Viaggio, Cherokee, 200, Giulietta
Large: three cars, probably Challenger, Charger, and 300; Ghibli and Quattroporte share quite a bit but for the moment, probably for political and “snob appeal” reasons, are not mentioned
Body-on-frame: two vehicles, possibly both Ram trucks
