I'm thinking of getting a Ford EV as my next car, prefer the features and looks to the equivalent Stellantis models.
That's hyperbole. They announced at 40K for the base model. Briefly sold it for that to people with early reservations, then jacked up the base price to like 48K. And a year later they kept on raising it, peaking, as I recall, at just under 60K. It was never 2x or 3x unless you are counting the worst examples of the dealer mark-up gouging. But that's not a problem Ford could do much to solve. And by 2024 they were selling for quite reasonable prices -- I got my extended range Flash for 50K out the door, which was a good bit less than the hybrid I had been shopping for.
There are routinely mark-ups on popular vehicles, and I bet there will be a period of time when this is true for the Fathom as well. Early adopters are willing to pay extra, so the market is there to take advantage of that.
> EREV (pretty much PHEV)
There is not much relationship between an EREV and a PHEV. An EREV is way, way closer to a BEV than it is to a hybrid. And I'll eat my hat if Ford actually releases an F150 EREV. That announcement was to mollify angry customers who thought Ford should not have killed the most popular EV truck on the market.
Frankly I'll be surprised if anyone seriously goes for EREVs. They make very little sense, which is why (AFAIK) it's only seen production once or twice in small numbers.
I actually have a different expectation regarding the popularity of EREVs. I think that for a certain segment, they'll be quite popular because they give the best of both worlds if the maintenance doesn't end up being too much more. They can end up being preferable for people who want to take long road trips without having to worry about charging.
