Hmmm, I don't remember the inflation button in the PMCS to adjust to the terrain. True, there is a button to keep the pressure in the tire, auto inflate of sorts, but that is more on the civilian model. What is much more common on the military model, as in that it is on ALL of them is the rubber sole that is inside so if the tire blows and you don't have a spare (and lets face it, you don't typically thanks S-4) you can still get our of the hot zone and back to the FOB

In my 6yrs of wrenching on HMMWV's, I have yet to see one other than on YouTube/discovery channel with CTIS (Central Tire Inflation System). While they are in the process of de-commissioning the HMMWV (any with 6.2L engines have a zero expenditure rate for faults, and therefore end up in the can yard for something as simple as an injector pump...) They will probably stay around for many more years before being completely phased out... Too much money to replace them all.

As for F/E, I've gotten anywhere between 9-13mpg hwy in them, and as low as 4mpg during field exercises. Not too bad considering their capabilities!

Saves me the trouble. In your search string include the word "Oshkosh".

There only needs to be one reason to be a pacifist. It stands on it's own.

Can you make it so it rotates into my Sig line automagically?

And, it needs to be said, LincVolt.

Yeah, it was always more of a " That's where it should by, hypathetically, in a thearehtical world. I did sell cars and saw one on the floor model of the H2...but that's about it. auto inflate, that's like sending Pv2 Murphy with a hammer to look for soft spots on the M1 or to go ask the 1SG for a prickyeight.

I don't judge people by what they drive simply by seeing them at a light. Circumstance of a vehicle purchase varies greatly so does the intended purpose. The H2 while seemingly ludicrous as a daily driven vehicle offers a lot of features standard and a comfortable ride for 5 passengers + cargo in just about any situation and road condition. Other vehicles of the class do not get much better in terms of fuel economy.

That said I can't vouch for any owners. Their personalities and reasons vary greatly. Although if they are approached about their choice of auto in an aggressive manner I would imagine them to be aggressive back.

If the project continues forward it would be interesting to see how the OP could improve the fuel economy without sacrificing the versatile nature of a full size SUV.

Big Dave says:
I could have sworn I outlined plans for both in the initial post.

Aero improvement on these cereal boxes is tougher than on pickups where a 'aerocap" can deliver you a solid 3 MPG.

But still I stick to my proven formula.

Diesel power
Manual transmission
Lowest (numerically) possible gearing


In the initial post I mentioned the T-56 transmission. I've been looking at its big brother - the Tremec 6060. Good for 600 ft-lb of torque. Considerably easier shifting than the ZF6-650 on my Super Duty. Where the ZF6-650 is a four speed with a granny and one overdrive, the 6060 is a four speed with two overdrives. It offers an outstanding variety of gear ratios. For a big SUV, you'd want the numerically highest low gear ratio and the 0.5:1 top overdrive. You could drop 70 MPH cruising (with stock rubber) down to 1400 RPM and gain a bunch of MPG.

I meant it more as a statement. I guess it should read "it would be interesting to see that the OP is able to improve MPG yet keep the versatility of a full size SUV"

The plans are pretty ambitious it would be cool to see it all done
