The "wonderful" ECOBOOST engines are not turbocharged for power - they're turbocharged for economy. The EcoBoost motors are designed to replace larger and more powerful (and, thereby less economical, more thirsty) motors. In previous comparison tests of the Forester and the Escape, they found that while the 2.0 EcoBoost could keep up and provided some spirited power (and was, iirc, only on the top line), the 1.6 EcoBoost that was on the rest and had to work too damn hard just to keep up with the NA 2.5 of the Forester and the 2.5 of the Mazda CX5 (at the time) and the 2.X of the RAV4 .... this was comparing the 2014 models.
This is the same thing with the new (and currently only JDM) 1.8 DIT motor in the Forester Sport and the Levorg - it's a smaller motor offering similar power (but better torque) as the 2.5 motor that is designed and tuned for economy and not power.
Jeep offers a V6 because the loyalists would be after them with torches and pitchforks if they only offered those Fiat sourced "multiair" 4 cylinder engines. It's there for torque as most off-roaders will still claim (and rightly so) that it is torque that gets you up n down those rocks and not HP. And that V6 gets dismal MPG - which may not be a big concern for some but it is a major deal breaker for others....
As for the Passport (oddly, the advertising for the Passport keeps popping up as I type this), they're trying. One of our former contributors (and a friend of mine) traded to the Passport after his XT bit the CVT dust. Of course, he abused the hell out of the CVT (he even admits to same) and has done some head-to-head comparisons on trail rides with others in SJ and SK Foresters. The Passport's system is at least as good as the Subaru Symmetrical AWD (with XMode). I should say his Passport is highly modified (lifted, better wheels n tires, etc.).
The "big" Bronco doesn't compare or compete at all with the Forester or the Brocno Sport and it never would. It's a totally different beast - just as the Wrangler and Cherokee are totally different beasts and are generally not cross-shopped.
Yes, the Passport is hindered - as are many compact and mid-size SUVs - by bigger wheels, low-profile ttires and that "look". It's a nod back to the designers who are still all living in the "Fast & Furious" moments when you slap big wheels and short tires on a vehicle to fill out the wheel wells and to provide better handling on road. As you allude to most drivers of hi-perf cars (Vette, Hellcats, Mustang, Camaro, Porsche and on and on) most don't drive even close to the limits these vehicles offer. And with many off-road SUVs and trucks, the same can be said. Most buyers of the Wrangler only see dirt when they go shopping for a Christmas tree or the Halloween Pumpkin at some farm - otherwise they're all parking lot crawlers...
For what it's worth, I've also had previous 4x4 trucks (back before the appellation SUV was a twinkle is some markeing maven's maw) - a Dodge Ramcharger and a Dodge Raider (Mitsu Montero in Dodge drag)... Back when you had to stop and move a lever for the auto-locking hubs to engage...
If the Forester Wilderness package does have some buyers and we see some volume - it may be that they will then start figuring out how to offer more off-road friendly features to the fairly capable Forester (and Outback) - but then again, maybe not. Only because if some yokel buys it and goes off-road and breaks it, it will be Subaru's fault and they'll have to fix it.
I still stand by my comment that the market for capable "soft-road" overlanding abled SUVs is small and may evaporate in time. Many of us that have modded our Foresters for overlanding know that it's not cheap and it's a blast but the typical SUV shopper could care less. For them it's more about the look... just like some of those big-@$$ trucks you see on today's roadways and highways that have gigantic wheels and tires and probably see less than 1% of the time doing what they're designed to do... For that matter, at least half of the pick-ups out there never haul more than a week or two of groceries in their beds.
