Why didn't Hummer go with 2WD w/selectable 4WD?

More complicated than that, but primarily the differential planetary splits the torque to 40/60; item 231. There is no torque converter in the t/case.

I think I see. Thats effectively a gear driven 40/60 except its through the chain. Then shifting into 4H moves the shaft, relative to the planetary, to a one-to-one drive(?) I would have thought they would have left street mode open with 50/50 and 4H lock 40/60 for OR.
It would seem to be very easy to design a 2WD select for this T-case.(?)

It would have been easier to go with a part time full wheel drive setup as used on 1/2 pickup trucks.

Exactly, something America has used almost universaly for decades.
Dropped the front D-shaft, shifted into 4Hlock; steering is lighter, thats for the wife.
It is also,,,,,,,uh,,,,,,,,quicker.....................
thats for me.

I don't understand your message....

This was an issue that almost prevented me from buying the H3 - but I decided to take the chance. The Explorer Sport (what I traded in for the H3) had the selectable 4WD. Honestly, I can not really see much of a difference in mileage, but then again the Explorer had almost 150,000 miles on it so the mileage wasn't as good as what a new one would have produced.

Regardless, if the research has been done, determining the 1mpg difference between the setups, I don't think I'll be losing any sleep over it. Still, choice is a good selling point and I am not sure I like big brother deciding what is best for me up-front. I always knew when I would need the 4wd...

This is likely an option that may have had underlying liability issues- i.e. some nutsmack sues GM and Hummer for an accident where the driver should have but didn't.

What does this even supposed to mean. If GM wanted a 2wd selectable transfer case, they would have put one in from one of the other lines. Very simple. Since it's a Hummer, it gets full-time 4wd, period.

"left street mode open with 50/50 and 4H lock 40/60 for OR". That just makes no sense. What 4wd vehicle has a split of 40/60 designed in it for off-road and why would it?

I didn't start this thread to have an argument over it. I was just curious as to why they might have chose Full Time 4wd. I didn't realize that the MPG differences were so negligible. It had turned into a decent discussion... for a while.

I'm with you.

You will NEVER know the answer since it was a decision made by a panel of people...

SO

Think up questions that CAN be answered...
