Ford should relabel it as an Edge/EXD (EXtenteD) and go back to the design board with R/awd front/center as a new 2012 Explorer concept. Use that new electrohydraulic drive coupling clutch to energize the FRONT driveline dynamically.
And while you're there why not give us a new N/A DFI engine, even a 4 cylinder if equivalent to the Venza I4 but w/DFI.
But of you LOVE boosted engine so much why not a....
West/Otto/Atkinson/Miller multi-mode 4 cylinder engine...??
15:1 base/native compression ratio.

The 2011 Explorer will start arriving in dealer lots by end of September. So less than 2 months to go!
However, Ford plans to do a "road show" with this vehicle. Its unclear which cities or towns are going to be on this show.

Hello akirby, if volkswagen is having good luck with these jetta TDI models here in the U.S. Ford should have just as much good luck and sales with diesels here. I would even buy an explorer then, considereing buying one anyway but would like to see how they stand up for first year. thanks

Show me where VW is making money on jetta TDI models in the U.S.
Ford has diesels readily available from Europe and Ford wants to make money, therefore if Ford thought it could make money with diesels then we'd already have them. The fact that nobody else outside of VW is trying to do diesels is all the proof you should need.
Europe favors diesel with taxes and lax emissions requirements which makes them more desirable and profitable. That doesn't exist in the U.S.

Thanks vrm! That is great news. So far everything I have seen, heard and researched looks very promising - especially the standard and optional advanced safety provisions. I will be focusing on the top line AWD model. For me it will now all come down to driver comfort and overall safety. This will be my first American car in about 30 years.
#243 of 716 Disabling Ford's F/awd System.

[Quote] You are correct that both #18 and #35 disables the rear drivetrain and at least in the '07 MMH, it should be #35 that is pulled as pulling #18 causes the MIL to turn on.
In my product design experiences, often the constraints of the marketing product specifications dampens design engineers ideas and findings and design engineers find ways to incorporate their discoveries in a manor which conforms with the marketing product specifications.
During design of the FEH, marketing wanted a vehicle where the hybrid system was transparent to the owner and fit the regular FE drivability. The product design engineers perhaps discovered that disabling the rear wheels in a AWD vehicle would yeild greater MPG and decreased PTU wear when not needed and suggested a switch be added. Adding this switch was outside the product specifications and was denied. So the engineers incorporated the switching function in a fuse and coupled it with the seat heaters which is another system that is not needed in summer.
Then when the FEH was redesigned in the '08 model, the original design engineers were gone or on different projects and the idea was lost. The seat heaters were move to the climate controls and they moved the power steering in its vacated position.
Or it could be an amazing coincidence. At any rate, pulling #35 in my '07 MMH has yeilded great results.[/quote]
No, it is generally well known, at least in the automotive drive train design engineering community, that having both the front and rear drives engaged, even partially engaged, continuously will result in so much driveline windup and tire scrubbing that the mechanical and tire life would be severely foreshortened.
And then the knowledge level of, or lack there-of, the general buying public must be considered.
Have a switch to turn on "AWD" mode...."..? Then you best have a serious public education program if you wish to sell it outside the "off-roader" venue. The general public is not even aware that the majority of the myriad of "AWD" designs, most especially F/awd designs, now available are not functional in the very conditions for which the vehicle was purchased. Then consider, if you will, that most of these F/awd designs are actually patently UNSAFE to life and limb when driven in those conditions.
Trust the general buying public, SUV buying public, to know when to use, and when NOT to use, an AWD "engage" switch, NEVER gonna happen.
These new F/awd systems are designed in an effort to somewhat alleviate the "patently unsafe" aspect of FWD vehicles. Ask someone with "first level" knowledge in the SUV community what's wrong with RWD or R/awd vehicles and they will undoubtedly respond with loss of control due to spin-outs or skidding.
Why doesn't the same thing apply to FWD and F/awd vehicles...?
Super sensitive TC (Traction Control), and VSC (Vehicle Stability Control) systems, that's why. And of course it helps mightily if at the time of threatened spin-outs due to excessive throttle you can automatically move a portion of the engine torque to the rear drive.
So now, rather than automatically derating (dethrottling) the engine in the lower gear ranges, you can have, and make use of, SAFELY make use of, engines in excess of 200HP in a FWD (F/awd) vehicle.
Detroit can now go back to selling what it's good at, selling HP. Ford SHO...F/AWD
EcoBoost = HP, NOT FE, actually to the detriment of FE since the EcoBoost engines must run in derated/detuned mode 99% of the time.
Just look at how, and why, the new Ford Explorer got castrated.

So how do you explain the 2.0L ecoboost best in class fuel economy?

"..Class.." as in 0-60 times and HP/Torque, NOT FE.
Take the VERY same engine, mill the head to raise the base/native compression to ~12:1, "wire" the wastegate fully open, and see a highway cruising FE improvement of not less than 15%
Check out the new DFI 4 cylinder in the Sonata.
Or use the new Toyota e/VVT-i technique now being used in the RX450h to shift the engine from Otto mode (15:1 CR) to Atkinson (13:1) and see a highway FE improvement in the range of 50%
And if you then still desire that stellar 0-60 time then add a variable speed/volume (CVT/PSD "driven") positive displacement SuperCharger(***) and use e/VVT-i to reduce the effective CR (before BOOST) to 10:1 or below with WOT.
*** The Atkinson engine mode is so efficient at using all of the power of combustion to push the piston downward that there is NOT enough energy left to spin a turbine, only enough energy left in the exhaust to heat the catalyst,
