Why are you assuming they'll be additional trucks and not replacements?  Only way they'd be add-ons is if they're commercially focused.

A new Edge, if it's a boring commodity unibody crossover blob like the previous two generations of Ford Edge, ain't happenin'. Remember what Jimbo and Jimbaum said?   We make products for people who work, and work with their hands, and we make passion products like Bronco and Mustang. And that’s what we do at Ford, and when we’ve gotten away from that formula, it hasn’t worked out, Jim Farley said.   Rule No. 1 at Ford: no boring products. Our industry is in the midst of a disruption. But one thing remains true: Great products always win. “We’re not trying to make toasters on wheels,” added Jim Baumbick, Ford’s vice president of advanced product development. “We’re not trying to make just commodity products. It’s all about emotion.”

I mean, who didn't understand this?

Hopefully the breakthrough processes Ford learned and developed thanks to the skunkworks will allow it to eke out a profit at the same selling price regardless of powertrain type.   Come on Ford big shots, make the wish I mentioned in the Ford Is Reinventing the F-150 thread come true!   Ideally, Ford will offer 2029 F-150 with these powertrain choices at the same starting price comparably equipped. That's my wish 😄 V8 V6 EcoBoost Hybrid Lightning EREV Lightning pure BEV

It is getting kinda ridiculous. We get it, trucks are profitable for Ford. But have so many truck models and variants that it's hard to keep track of it all is a little absurd. I wish Ford put some of that money into something like a new edge, instead of trying to make a 5th, 6th, 7th truck. I think they're starting to slice things too thin. 

Exactly.  This has nothing to do with selling price.  It's Ford trying to eke out a profit at the same selling price.

Which is why I think it will replace Ranger (worldwide)and possibly Maverick too.

It's good that they have all of the other segments in the lineup covered, so they have time/funds to squeeze an 87th truck into the lineup!

Well if more people actually bought the lightning, this would be a moot point, thus why an EREV is coming-because hopefully that will sell more even with it being "more complex". The "shortcomings" of the EV Lightning made it a not a good choice for the vast majority of truck buyers. Also that is why IMO I think the CE1 pickup will be more successful-it will actually Aline better for the EV buyer and not be burdened with the expectations that the F-150 might have to carry-literarily and figuratively    As for cost, I'd argue that the EREV will be the same price or cheaper (or at least cheaper for Ford to manufacture) then the EV Lightning.
