I have seen both Bronco Sport and Bronco in high articulation situations.I remember the videos posted on Allpar of these FWD based Jeeps on the portable obstacle course at some auto show. Articulation was minimal and the Jeeps violently tilted from one side to another as they went over the obstacles with a wheel lifted in the air - compare that to a Wrangler doing the same course.
It would be interesting to see the Fords in the same setup. See how Bronco Sport and especially Bronco does in articulation.
The Bronco Sport has the least articulation, of course. It is independent suspension all around, but Ford gave it more articulation and height than the Jeeps. It is competitive with the Cherokee with regard to approach/departure, ground clearance, etc. Bronco Sport lacks a mechanical locker (it uses locking clutches that have overheated in some tests).
I have not seen a Bronco Sport be compared directly to a Cherokee.....only to a Compass and Renegade, which the Bronco Sport beat fairly easily.
The Bronco is another matter. It has great articulation, even with the IFS. It will keep all four wheels planted up to 95% of the Wrangler's articulation. But the Bronco front suspension keeps the tires planted more firmly than the Wrangler since a solid axle shifts weight to the lower side more than an IFS. The 35s give it great ground clearance. When not literally crawling, the Bronco destroys the Wrangler with more steady and sure absorption of bumps and dips. Therefore, those driving into a camp or into an off-road park will have a much better time than if they were driving a Wrangler.
The Bronco Sport was definitely done on the cheap. Lousy interior materials and a lack of some off-road chops demonstrates this. It still beats anything in its class (Cherokee unknown). I predict if the sales remain strong, then the refresh and next generation will be a big surprise.
I predict the Bronco will be name the new "king' of the off-road. I predict Wrangler sales will be hurt by at least 30%, probably more.
All this is predicated on no major quality gaffes from Ford on the Bronco.
