That would be old school style thinking, i wouldn't mind the 300 having a hellcat motor vs the charger.
Look at M and Amg, they put their high performance motors in everything, coupes, midsize cars, suvs, crossovers, etc etc.
In order to recoup r&d and attract more people having a 2 door + 4 door + suv was very important. Where they went wrong was pricing the suv too high, as far as giving the charger the hellcat vs the 300 goes it was probably moreso with them killing off Chrysler than anything else.
Chrysler is on the chopping block, ram and jeep are the only things keeping fca afloat, alpha sales are ehhh, dodge pulls its own weight but nothing like the units the new ram and jeep have always been doing.
