Pretty sure they expanded the skunkworks quite a bit recently. I think you'll see them taking on more and more as new vehicles are developed and the legacy teams and processes wither and die. They do need the legacy institutional knowledge on production logistics but you don't want to dilute the new thinking and have the legacy processes and mindsets take over again.
Bronco pickup would support significantly higher ATPs and the new pickup should be significantly cheaper to build. May or may not be unibody but I would expect it to replace T6 Ranger globally if it's successful.
It's about innovation and cost control, neither of which apply to T6 Ranger.
AWD with open diffs is really just 2 wheel drive (one front and one rear). Ford's system compensates by braking the spinning wheel(s) to force traction to the other wheel and it works pretty well in most use cases. Having a locking rear differential really helps.
And almost half of the 9M this year was a software error for trailer lights that will be fixed OTA.
When they catch up on all the old problems you'll see a dramatic dropoff.
