At this point it seems only those who read tea leaves and bones know the answer to that question. FCA apparently is not big on sharing information.
I agree , it takes a lot of money and even more time to do anything to get these things epa certified and tested for the road. That is why most manufactures cut back models and engines on vehicles.I think our only hope for info on this is our inside guy who works on the engine line. When he says they are in the factor then it is getting close.
