The Ford F150 Raptor has independent front suspension. That one seems to work pretty well off road. (So, for that matter, does the Ranger Raptor available elsewhere in the world.)
Lifting a wheel off the ground doesn't matter much if you can get past the obstacle anyhow, especially if it has some way of transferring torque to the other side, whether by locked diff or selectively applied brakes (which is generally how this situation is handled nowadays).
It will be fine ...
It's not just traction, and speaking of that, brake force "limited" slip is nothing near a true locking diff for when it's needed. The ability of a solid axle is that it will have more articulation than an independent will, in which case it will provide for much better stability in off-road situations. In the picture with the wheel up, perhaps the terrain isn't too tough. But imagine if it's a more hazardous obstacle, having a wheel lifted will make the vehicle much less table, and tipping or rolling can easily result. A better articulating system helps curtail that.I TOTALLY grant that I am not an off-roader.
A locking diff means you get traction from the wheel that remains on the ground while the one that's in the air doesn't do anything.
The common-nowadays strategy of using the traction control to apply a brake to a spinning wheel, means you get traction from the wheel that remains on the ground.
And I UNDERSTAND that if you are seriously rock crawling and need 2 feet of suspension travel and lifted a foot higher than stock, the independent suspension is not going to work for you. (Heck, the stock axle locating linkage on a Wrangler is not going to work for you.) For those people, they will keep buying Wranglers. I am quite sure that Ford has done the math, and established that the IFS design is good enough for most people, (actually better for most people due to better on-road manners), and they are better off sacrificing the very small number of sales to the serious rock-crawler crowd in order to get more sales to the average person who might just go on a normal gravel road or pathway from time to time.
IFS works fine for Raptor, 4Runner, all of the half-ton pickups, etc. It will be fine here.
I'm sure the new Bronco will have center mounted A arms and will be mid engine because they won't have enough room to mount the engine between the suspension arms. :screwy: KOH race winners have nothing to do with the factory suspension components. It will be the same crappy SLA front suspension everyone else uses.King of the Hammers winner Jason Scherer doesn't seem to have any problems with IFS.
