It appears to me that Stellantis in North America isn't ignoring the current market dynamics, it's more like they simply aren't paying close attention. I offer the lack of offering a range extender option as proof of this. (As you pointed out.) With all the recent management changes in the Stellantis universe, I don't know what the current status of Leap Motors in the organization is, but they now have vehicles in production which offer a range extender. The managers in the Stellantis Ivory Tower should be aware of this fact. Toyota made their electrification plans public a year ago and are currently rolling out actual products. Some of these new products have pure battery electric drives, while other vehicles will have a generational leap in plugin hybrid technology.
This is strictly my opinion based on personal observation, but the reason that the plugin vehicles from CDJR don't sell is their marketing is an ongoing disaster. The engineering focus was misdirected by the previous CEO and the result is the present day Charger Daytona debacle. Focussing exclusively on battery electric drive while decimating the engineering ranks kneecapped mild and plugin hybrid development. The Pacifica's hybrid system was stagnant and was leapfrogged by Ford, Toyota, and the Koreans.
Getting back to the Chrysler brand specifically, the Halcyon concept and the Charger Daytona EV have one thing in common. Nobody asked for this. In the Charger's case it is overpriced and overweight. There is nothing Chrysler about the Halcyon. In a typical Marxist maneuver, it is a rebuke and total break with the past. On the other end of the spectrum a Chrysler 300 based on the new Charger will fail because the idea is well past its sell by date.
The Chrysler concepts we stood up and saluted are the Citadel and the Chrysler 200. Although the Citadel concept was introduced over 25 years ago, amazingly Honda thought it was fresh enough to copy some of the elements for an upcoming EV, while an unnamed Chinese brand will be using a descendent of the hybrid system, but with an e-axle in the rear instead of the mechanical driveshaft of the concept. The Chrysler 200C concept which toured the auto show circuit in 2009 demonstrates what a battery electric Chrysler sedan should be, a contemporary design that retains the brand's DNA. It and the other CDJ plugin concepts on the auto show tour featured a range extended electric drive. This technology is what supports the New Energy Vehicle initiative in East Asia.
If I ran the circus, Chrysler would be a people mover brand as was proposed before all the net zero craziness, but with a new energy twist under the hood.
