My problem is the width, though. Let's see...
Ranger is 73.3" wide.
A regular F-150 is 79.9" wide
Raptor is 86.3" wide, +6.4" over the regular model
Assuming Bronco is the same width as Ranger (which it may grow slightly for the NG, and Bronco is on the NG platform), a Bronco Raptor could theoretically be 79.7, which is virtually the same width as the regular F-150, but still 6.6" narrower than the F-150 Raptor. I don't see any reduced track width on that model, which appears to otherwise use a completely stock Raptor body (not a hacked up narrowed version). The wheels aren't sitting way inside the wheel wells like they would if they were just hiding a Ranger platform under a F-150 body.
