How high up off the ground your tub is, is not the same as ground clearance which is the lowest point hanging down, if I am not mistaken.
Ford Escapes are higher off the ground than a Forester, but due to those (I think wishbone suspension) things next to the wheels that are part of the suspension, they do not have a "higher" ground clearance. Next time you are behind an Escape/Tribute take a look at what I am talking about.
I have driven in ruts in Utah on pretty easy off road type stuff where those things would have been carving rocks and dirt or lifting the whole thing up in the air while bending no doubt while a Forester chugged along...
And thus my earlier question... I can see a better design, but you are still going to need some type of lateral structure you do not need on the straight down strut/spring setup on present Suby's. And that is going to seemingly have some impact on "clear" ground clearance.

It's all in the design of the vehicle. Don't forget we are talking about a FORD here. As I said I have taken my Armada off-road, done some rock crawling etc. That has double (triple actually I think) rear wishbone suspension and I got hung up on the running boards, not the suspension pieces.
We'll have to see how it looks and drives when it comes out.
No offense to Forester owners out there but the Forester is not an "off-road" vehicle, at best it's a dirt-road vehicle, but let's be honest it's no Rubicon.
They may have different shaped wishbones for the forester v. impreza. Here is a shot I took at NYIAS of the underside:

Useful pics. You can see the lower links aren't really much lower than the center diffy. Maybe an inch, plus they're closer to the wheel.
If you look at the same view of an Escape or CR-V, they are several inches lower than the rear diffy.
Ha ha, found a really funny pic:
You can see, near the rear wheel, just how low those lateral link are.

I agree that one of the seldom touted advantages of the Forester is it's clean undercarriage. Sure it's not set up for real off-roading but I'd rather drive it on rough forest service roads than a Escape or CRV (even though they technically have a higher ground clearance). Having said that, the strut towers do indeed take up a lot of interior room so if they can manage to make them less intrusive (without messing up the undercarriage) that would be great.
I don't see the center of gravity issue being of much concern unless you plan on racing one. The Forester already has a much lower CG than anything else in its class. Besides, it's a utility vehicle intended to haul stuff. That the XT can also haul A$$ is just an added benefit

Lower CG will give it a better rollover score, it's all about the scores.

I think suby's are or were the only "suv" (intentional small case to pre-empt that argument hopefully) that did/does NOT require the rollover sticker right in front of your face presently. I can't be sure about the Tribeca though...
These "rollover" "lower center of gravity" arguments would be great for other vehicles, but that has always been one of Suby's best features...

Do the others in the classes against the Forester and Outback have rollover stickers? Not sure though.
Heck I'm not even sure my Armada has that sticker in it, I'll have to check it next time I'm in it.

I seem to recall that they use a rather simplistic mathematical equation to determine the CG and accompanying rollover score. Something like they don't actually determine the CG but just estimate it based on HT/WT/Ground Clerance/etc. Thus it doesn't take into account the boxer engine's lower CG nor would it care what type of suspension was used.
I'm sure if I'm wrong someone will set me straight

No, I think you're correct Frank.
