I think the Bronco would work better if it filled the hole left by the FJ Cruiser (and the languishing Xterra). Use the Supercab F150 (or Ranger) doors to give it a short wheel base but access to a rear seat. Fixed roof to offer something different than the Jeep to those that want it.
Base model essentially has the F150's FX4 suspension, top end model goes Raptor-lite and give it the option of 2.7 Ecoboost for the base, 3.5 Ecoboost HO for the top end.
All of this scaled down to Ranger-equivalent in case those two share bits.
Of course that's exactly what they're
going to do, shared platform and parts. I was saying that in a just and perfect world, the new Bronco would go head-to-head with what it was originally designed to compete with: Jeep.
A generic SUV version that would essentially be a 2 door Expedition will be boring, and people probably won't buy it. (Who buys 2 door SUVs anymore? Who even sells them?) but people do want fun convertible 4x4s. As the sales of the Wrangler definitely show. Also contributed to by the massive brand appeal.
The Bronco also has nameplate appeal too. At least with older people. And it's also a rather evocative name for those not familiar with it. The problem is, what killed it in the first place (the mainstream appearance of 4 door SUVs) will probably kill it again.
That's why I said it'd be better to compete in its original market. Small dedicated 4x4s.
The concept they released about 10 years ago was practically perfect. If they toned it down a bit, gave it a proper driveline (V8, live axles at both ends), and slightly modernised the interior (touchscreens, touchscreens everywhere), and played up the heritage in advertising, it'd probably sell like hotcakes.
