Truthfully, I don't think they will, but they could. Light duty (I just checked the order guides) covers everything that is trucks up to the F-600. F-650 and F-750 are under Medium Trucks. Actually, keeping Maverick, Fathom, and Ranger OUT of the F-series adds a touch of plausibility to it, but only a touch. I've always thought it hurts GM a bit having Silverado and Sierra under different brands as far as the "best selling" bragging rights goes. Probably not enough to matter, but still.

Once again For North America changing direction on Electrification changed many things. Originally T6.2 with refreshed was projected to continue well into the early 2030s and for Ranger and Everest, that may still be the case. Bronco was the lead design vehicle on T6.2 and if that is the case, Ford may already working on next Gen Bronco basic engineering now, so ideal to bake in the North American product envelope now. It could be as simple as Nth American vehicles all use Bronco Suspension elements and track dimensions, a sort of decoupling with Ranger/Everest so the globals can concentrate on what those markets still need. The Ranger Super Duty may be an indicator to what is well within reach with more of those Nth American Bronco elements rather than just an add on product.   To simplify, since North America will shoulder more of the costs, they get a bigger say in the vehicles they want. Conversely, the Ranger and Everest can use slightly altered versions of those  engineering modules and save a ton of development costs, it’s a big win win.

Which will be disingenuous, IMO, given that you're now lumping a midsize truck in with the full sizers.   By that logic, why not call it F-050 Maverick, and F-075 Fathom.   Don't forget F-125 Bronco truck!

But will they?  They don't lump the F650 & F750 in with the F-Series numbers (granted, those numbers are miniscule compared to F1/2/3/4/550 and F600).  I don't think they will the F100 either.  That'll bring a lot of negative press to their claim of "America's Best Selling Trucks ## years straight."

Ooooh, I know the answer to this one!!!!! Calling it the F-100 would allow Ford to lump it into sales numbers for the F-Series, which window stickers proudly state as America's Best Selling Trucks 49 years straight.

And doesn't plug it in.....

I don't think it will be much larger and they can call it f100 here and ranger globally.  

I’m not going anywhere since I have to be here when @Sherminator98buys a PHEV. That will be so much fun!

It would surprise me if they gave the international Ranger a different name. It would be like North America deciding to rename the F-150. But anything is possible.

Thinking here, with the 25 MPH limit, does the Kei come without an airbag or only a drivers steering wheel air bag. Makes you wonder how cheap they could really make these without many of the typical safety and creature comforts.
