I believe the 3.2 Pentastar used in the Jeep Cherokee was also smaller in physical dimensions as well as displacement. As I recall it had a shorter deck height, lower intake manifold, and other small details.
Honda had a big presentation today on their EV strategy. Basically the new entry level models will be hybrids and battery electric. For passenger vehicles, Honda will try to avoid large battery packs to achieve long distances on battery range. The company will instead focus on light weight and other means for efficiency. Honda also announced new hybrid options with e-axles for their North American products, including the HRV. Mitsubishi announced to their dealers this week that they are revamping the lineup in North America. It was announced a while ago that the Mirage is going away after this model year. In its place will be a larger (C-segment), more upscale crossover offering a PHEV powertrain.
Just my opinion---> Where the current emissions and fuel economy regulations presently stand is that it there is no difference between selling an ICE power only, economy car, or an ICE power only, high end car. It makes no sense selling low margin econoboxes when each unit sold hurts the CAFE as much as a high margin muscle car. There is a growing list of entry level vehicles which are either disappearing from our market or moving upscale. Toyota and Honda are increasing hybrid availability to their entry level offerings. An an example of what a future pure ICE power offering might look like, the Toyota GR Corolla is a preview. It is a tiny performance model close to nearly twice the price of a base Corolla.Toyota can afford the hit on the CAFE average because they will probably sell hundreds of thousands of hybrid models to cover for it.
The range extender system for the Ram pickup was designed in house and is designed around the rear drive based STLA frame platform. For other Stellantis products, I have to wonder if any STLA medium and small based vehicles were to use the Leapmotor EREV generator and motor units. If so, the proposed anti-China tariffs will hurt. The PHEV systems are different from this.
I think what we will see is 48V mild hybrid and high voltage PHEV power trains with the ZF 8-speed. When the cash for clunkers was happening back in 2009, the top selling vehicle for clunker replacement was the Toyota Prius. The present state of the art 48V mild hybrid systems will offer the same electric drive performance as that 2009 Prius hybrid.
Finally, my idea for an entry level performance model for Dodge would be a decontented Hornet, a front drive model with the 2 liter. Dodge also should drop the current Hornet's mechanical AWD setup and replace that with the e-Hybrid and e-axle system used in the Compass. They should use the 2-liter GME with that.
