I highly doubt that the I6 Hurricane will ever end up in the HD Trucks, so they're going to need to update their V8 engine offering in the HD Trucks at some point no matter what.
Maybe we'll start to hear something about a new HD Truck V8 engine program AFTER the UAW contract is negotiated. And then maybe a little while later, that motor winds up in a very exclusive car/light truck model or two.
Also, just my opinion, but I think the reason everything has been pushed back constantly is because FCA was behind in implementing an electrification strategy, so once they merged with Peugeot, they decided to string out the existing models as long as possible, while they worked on the new multi energy platforms.
After watching them go through multiple near death experiences in my lifetime, I can't find fault with the logic of trying to squeeze out as much $$ from what they had, instead of wasting billions on half assed placeholder products for 2-3 years until the all new platforms were ready. Besides, who knows if they even had enough time to come up with stop gaps that would meet all the regulations.
Just my opinion, but I bet there's a lot going on behind the scenes that goes against the idea that Stellantis is going all 100% electric for the North American Market.
I just don't think this is the time for them to talk about it publicly.
