Hi, new to the board and planning to purchase a H3 in the summer. Does anyone know if there are any plans to offer a Chevy small block V8 in the 2007 model year?
Thanks.

From what I recall, nothing definite on a bigger engine but the '07 will have more HP out of the same engine.

Damn First Hummer, who told you that?
http://hometown.aol.com/f5fstop01/im...orlaughing.gif
To the original question, you won't see a V8 in '07. Maybe a diesel late in the model year. As for the disbeliever on the drivetrain components, if, and I do say if (small if), a V8 is installed, it will have the same axles and Tcases; won't mention the trans, but if it is different it is not due to torque, but for fuel mileage...all I will say on that. And guess what; they can handle the additional torque and HP. The drivetrain components are a lot heftier than people think.
Ask me how I know. But I can't say. (I believe we have already had this discussion, and we hopefully, we both agree to disagree.)
As for the statement about the H3 having a great balance of HP and gearing already, that I agree with 1000%. In my opinion, the reports of it being underpowered for on-road use, and for off-road is greatly exaggerated. No, it won't do over 99 mph, no it won't do 0-60 in under 8 seconds, but then again, it is a large vehicle that has enough power to pull away from a light with dignity, merge on an interstate with authority, and climb mountains like a Rocky Mountain Big Horn Sheep; and it does it in great comfort. That is all I ask for in this vehicle.

So IF GM were to use a different transmission, IF they were putting in a 5.3L V8, would they bump up the transmission from 4- to 6-speeds to improve fuel economy?

Re: H3 w/ V8 in near future?
Hey the V8 might happen in the H3 just in time to coincide with $4.00+ per gallon gas prices. Not necessarily the path to significantly increased sales.

evomind,
See your point on gas mileage, yea it looks like many of us are seeing around 15-17mpg (my personal experience over 8000 miles so far) on a regular basis with our H3's. More cubic inches will definitely mean more gas consumption. And GM financially is a debt-ridden disaster with limited resources for spending on nice to have projects.
If I wanted a faster on-road SUV, there were plenty of choices when I bought the H3 and traded my faster Highlander.

Man, I'd love to see 15-17mpg from my H3. I can't seem to break 13mpg. Am I totally in the minortiy here or is anyone else getting lower than expected mileage?

Will the 07 use the same block with a different head/cams/ compression/ and intake and exhaust manifolds to generate more power ? Or will it be an add-on like a Turbo or SC? Thanks.

fstop,I was talking with the service Manager a few weeks ago about the V8 and he told me that you will see the 5300 V8 in 08.You can take that as far as you can throw a BCM Module oh **** wait i need that.

I was told that in 08 the 5300 v8 is going into the H3 with 295 HP.Diesel in 07 V8 in 08.

Do not think that the V8 has to mean less mileage. The new Tahoe is rated at 20mpg on the highway with a V8.

I agree. If you ever wonder why the H3 downshifts so much from 4th to 3rd, it's because of the shift speed versus %TPS data. Here is this data from a colorado I5 (which is very similar to the H3). It's complicated, but if you look at it enough it will break apart. Assume you are applying 19% throttle, you'll shift into 2nd gear at 17.9 MPH, then into 3rd at 32.6 MPH, then into 4th at 44.1 MPH. If you blip the throttle by about 12 - 13% (to 31% throttle) the H3 will kick down to 3rd. This is why the H3 downshifts so much - not saying good or bad design - just saying why it does. It takes a bigger throttle blip (20% or more) to downshift from 2nd and 3rd. With a 5.3L, the downshift %TPS can be moved higher and the upper gears (lower engine RPM and lower parasitic losses) can be reached at lower RPMs. I feel that the 5.3L could have the same or better fuel economy as the I5 especially with DOD. I'd even consider 4.11:1 diferentials and a lower low range gear for better fuel economy and the same off road gearing.

Re: H3 w/ V8 in near future?
In short a V8 has the potential for slightly better highway mileage, that would be great. No way it's going to have better city or combined mileage though.

This data is directly from the Chevy website for Silverado 1500 trucks. The 4.3 L V6 (195 HP, 260 lb-ft) 4x4 with a 4-speed auto gets 15/18 MPG city/highway.
The 5.3 L V8 (295 HP, 335 lb-ft) 4x4 with a 4-speed auto gets 15/19 MPG city/highway.
This is just one example of no loss in city MPG but better highway MPG.

Re: H3 w/ V8 in near future?
Good to know about possible similar mediocre gas mileage with a V8. Key word is possible since Hummer aerodynamics and tire selections are unique which impact highway mileage. And all the 4wd trucks listed above have lower city mileage than the H3.
Note 2006 H3 EPA mileage (all H3's have 4wd as standard for a reason):
16/19 auto
16/20 manual
