V8 H3 Alpha

[Captain of the Titanic]

I was at the Plano TX Hummer dealership getting my H2 serviced and overheard a man talking about waiting 6 months or so for the new H3 Alpha with the V8. He seemed to be certain in his comments about it, saying that he felt that the wait was worth it, and even said that the price will be right around 35K.

I was surprised to hear anything about a V8 H3. I had only heard about a Turbo I5, which I personally felt would be the icing on the cake for a H3, since it's only downfall is highway passing.

Has anyone else heard about a 2007/early 2008 V8 H3?

discussed several times but so you don't have to look, ya there most likely almost certainly putting a V8 into the H3 for 2008, will it be an Alpha model we dont know that yet.

Dream on about the V8...

[3Hummer]

thats why I said almost certainly and not they are, I have a good feeling though with a lot of people wanting a V8 in it they will do it. Also when i was at Hummer the sales women said there most likely putting a V8 into it. But again no one ever knows till your able to order it for sure.

I suppose that's true. The conversation was pretty cut and dried, though.

I was just surprised that it would be the V8 over the Turbo I5. I would think the V8 would end up with lousy mileage over the Turbo. I didn't think the H3 had any power problems except trying to pass at highway speeds...

I guess I'm not the first person to overhear H3 engine rumors at the dealership....:D

[Diabolus]

They're putting a V8 in the H3????? :eek:

[whaaaaT]

yea yea just like it was gonna come with a v8. then it was getting a v8 and it got a 3.7 insted now its another v8 rumor. I seriously doubt you will ever see a v8 in it. It doesnt even have a 6. Im sure your chances of a 6 are far better.

:D

Two things, bigger motor does NOT mean worse mileage. Our Denali gets almost the same mileage as our H3. The engine has to work less hard. With the H3, any hill, any towing, and you're testing the pedal to floor minimal clearance quite frequently. With the Denali, you NEVER squash the carpet unless you mean it! We had a 5.3 Yukon before our 6.0 Denali. The 6.0 performs much better and gets even better mileage than the 5.3.

The H3 is heavy beyond it's size, and it needs a larger motor accordingly for people that are used to having performance on the road because face it, the H3 is used on the road.

The H3 most certainly has a power problem, unless you're not used to anything else. It's more than adequate, particularly offroad because of the 4.56 gears and the 4:1 tcase.

IF they ever put the V8 in there, they'll most certainly need to upgrade the axles. Mine's in the shop for the second time for the rear end. (no biggy, they're covering it, I'm ok) I'd LOVE to see a 6.0 with a portal driven front axle with locker, and a Corporate 14 bolt with e-locker. THEN, you'd have what I'd consider worthy of the Alpha badge.

[f5fstop]

Turbo has NEVER been considered. Now if they did put a V8 in the H3, and I'm only speculating, the mileage would no be off that much from the I-5, and might be better on the highway end. That is if they add a V8 with active fuel management (aka displacement on demand), as they do in the 6.2 liter in the Escalade. There will not be a 6.2L so don't anyone get all excited about that sentence.:clapping:
I would imagine, if there was a V8 coming, the rear axle would stay the same, but the front axle would be different. Rear axle is strong, and in those cases where one was replaced and then it went, I would bet under the majority of cases, it was incorrectly installed by the technician. There was some problems with early axles having lapping compound left on the ring/pinion gears from the AAM factory.

As for power, I feel the 3.5L is adequate on the highways and off-road. Then again, for power take the Vette out, for normal driving on the highways take the H3. No, it will not beat the Mustang, but let's face it, most people don't race the engine and want to drag an H3, and vice versa.
If I can keep it at 80 plus on the interstates without straining the engine, then I don't have a problem with a vehicle's performance. Again, if I want to be the quickest off the line, I will take out 700+ HP in a 3000 lb car.

[Viet Nam Vette]

After waiting over a year to get my 07 H3..I am not the least bit dissipointed in power of the H3. Why...well for one I realize what this Rig is. It's a 4900 lb SUV with 33" tires and 4 wheel drive. It's got great balls off the line and zips thru traffic just like any other vehical out their.

It handles grate..stops very well and has excellent manors. I also understand that it lacks some power for passing...but I take this into account when driving and passing. It's an SUV..not my 65 Corvette with a 502 BB.... That's a different story.

I don't see a V8 as a solution for better fuel economy. The brick-like shape, nearly 5000 pound curb weight and offroad drivetrain of the H3 are the main reasons for the mediocre gas mileage and it's really no surprise.

The current EPA mileage ratings don't resemble reality anyway.

Of course dreaming of a V8 for better road performance would sure be nice...

Have to understand why a larger engine can obtain better fuel mileage.
To obtain a set speed, you don't have to give it as much fuel. True, you are actually using fuel in three more cylinders, but are you using as much to move the mass off the line.
Highway driving, now you are using five cylinders at all time. With an AFM V8, on the highway, you will only be using 4-cylinders. Good case is the Escalade that went to a bigger engine and is obtaining better fuel. Part of that IS due to the six speed trans and the gearing, but part is due to the AFM system used on the engine.
As for EPA, remember, 2008 ushers in the new ratings, so the V8 will appear to get worse, while a I-5 will also appear to obtain worse milage than the 2007.
Time will tell if it gets better mileage, the same mileage or a few miles per gallon less.
Time will tell if there is a V8, and then we get to see how GM Marketing markets the vehicle to the public.

[RuggedH2]

Mileage is a consideration, but the power would be reason enough for me.

Screw the whiners, bring the horsepower and torque! :excited:

Exactlly! There are other SUVs close to the same weight with better gas milage and more power/quicker than the H3. What man in their right mind would be against more power?

[f5fstop]

that's the part that has me skeered

Skeers me too. Look at this year, the released two really nice new colors, but only offer them on the bling model. Actually stopped one sale of a 1007, since I was willing to trade in for a Sunset Orange Lux with an off-road package, and I can't get it...thanks to marketing.

Here's what I can imagine....
IF there is a V8, it will only be available in the luxury package, maybe with an off-road package, maybe not. But you can bet the option price for a V8, IF THERE IS ONE, will be high.

[Mark805]

I dont know about all you gas milage folks but I bought my HUMMER for the companies reputation for fuel saving vehicles :p

/sarcasm off

If there is a V8 and the mileage sucks... Oh well...

The HUMMER is a utility vehicle... its doesn't slip through the air... its designed to get me where I want to go when I want to get there pretty much when I want too no matter the conditions. /hug my H3

The V8 would only be more icing on the already sweet cake.

Just my opinion

I see the point about the possibility of a marginal improvement in highway only mileage with a V8. But the AWD Escalade probably running premium gets 13/19 EPA mpg vs. H3 3.5 16/19 EPA mpg (comparing apples to apples). so the possibility looks somewhat bleak. Of course the Escalade is heavier but it's much more aero, running street tires, tall gearing, etc.

I'm sure GM is trying to figure what (if any) incremental sales volume increase would result from a V8 option since this really is a business decision. But I would like to hope...

[marin8703]

IF GM was to drop a V8 in the H3 would teh front be modified for the bigger engine or would it fit under the hood as it is now? and also someone mentioned that is a V8 is put in the front axle would be changed, could that possibly mean cast iron with a locker?

oh and i also think the H3 will get the same milage if just engine (without AFM) is changed, but since it will get a new trans (6 speed) milage should probly be better, and thats if anything happens at all. Thats just how i look at it. its just simple physics no matter who pulling what, its gona take teh same energy to move it, juss because its a V8 that does mean the H3 is gona get any lighter, if anything heavier.

if this is an 08 model when do they go on sale? im not familiar when hummer starts selling their 08 models....

Model change this year for Colorado, Canyon and H3 will be toward the end of June. You wouldn't see any 2008 models in quanity at a dealership until September.

[rsm688]

sweet, so if i ordered one the day they were available would i have a chanve to have it in by the middle of august? (thats when i head to college)


thanks,

Just remember first 2 weeks of July is vacation down time at GM. You might call the Hummer help number and ask when you could order a 2008. But options change from year to year and that information might not be available if you order too early.

Under powered = more rpms = ineficcient=suffering mileage. Adequate power = less rpms, yada yada.

I wish it was that simple....

[Alan06SUT]

I wish it was that simple.... You are making it too complicated. Weight is the biggest thing. Aero only comes into play at higher speeds (hwy mileage). Its all about getting the right motor for the right vehicle. The torque and horsepower curves need to jive with the everyday use/reqirements of the vehicle. An underpowered vehilcle is constantly working to keep up, and adequately powered vehilce remains in the engine's sweets spots longer.

E F F I C I E N C Y

it's all about the ability to produce the power with the given amount of fuel.... all other factors remaining the same. Obviously there has to be a breakover point in the design of a engine to reach the best efficiency to utilize all the fuel and gulp enough air to burn with it as it forces it's power against the forces of the vehicle that want to make it remain stopped.

If you simply assumed the smaller you go the better, a motorcycle engine would be the best, but it won't since it would be at full throttle all the time just to keep the vehicle from stopping.

Small engines don't belong in trucks.

Agreed, right motor for right vehicle makes a lot of sense. When GM picked the I5 for the H3, mileage was a big consideration. Other engines had advantages in the power department but not better mileage. All Hummers are underpowered for aggressive road driving by American standards, but they are optimized by design to have serious offroad capability. It's all relative, compare the mediocre mileage of the H3 to the really low mileage of an H2 and the difference is significant (20-25% difference). A Hummer is not an Element, but I've heard some have cross-shopped both.:D

[Sewie]

When GM picked the I5 for the H3, mileage was a big consideration.

I don't think the mileage was as much an issue in choosing the I5 as the fact that it was already available. Why plonk all the money into R&D when you already have an engine that is capable enough and that you can drop right in.

Now that the H3 is released and successful, and enough people are complaining about power, it makes sense for GM to look at other options.

had nothing to do with the fact that it was already in the colo/canyon

[H3 Builder]

When you talk about any vehicle you always hear the same thing, "IT NEEDS MORE POWER". Now I agree that extra power is always better, but GM had to make a choice and went with the same power plant as the Colorado engine. If you noticed, GM has been bringing new products to market at a reasonable price. If you start adding this and that, it can bring the price up. If GM thinks there is a market and sell plenty of product to be worth while, then the buisness case is made, then things happen.

[usetosellhummer]

It does not need a v-8. I heard the same thing all the time selling. power, power, power. well then why do so many bitch about MPG. I'm sick of it. hay if you don't like the I-5 then don't buy the damn truck
I love it.

I understand the gist of what you're saying but, and this is a butt as big as Jay-Lo's, it IS true. The H3 does need more power. For any other time that it's being used other than on the trail, it's considered anemic. When I drive our Denali to work for a few days, then jump in the H3, I feel like I'm flogging a tired old mule. No more passing, no more hurrying, it just takes longer to get home even. It takes the joy out of driving on the road, and that's DAMNED important. What's important too is that it's not a comfortable feeling to know that instead of using an engine at 60% of it's power range, I'm nearing 100% quite frequently. An engine that's utilized at more of it's load rating is going to fail sooner, and that's the truth of it.

Adequate just doesn't cut it when you're in the auto business. What's needed is to pound the everlovin' krap out of the competition. Hell, our Denali only gets two mpg less than the H3. How many of you'd give up the 2mpg for all that power? All that driveability? I know I would!

Look at what happened to the SSR. I understand that it's a different application as well but the point is this: It was heavy, and underpowered when it was introduced with the krappy 5.3 and people hated it, sound familiar? We've had Yukons back to back, one with the 5.3, then the Denali with the 6.0. It was the same thing, the enjoyment of one over the other is truly an important factor. What doesn't seem like much on paper, made a huge difference in how we feel about the vehicle.

Hummer did indeed think out of the box on many issues with the H3, but on some of them, they're firmly planted IN the box like a snitch gangster's feet in concrete. The weak front end is one, and the engine's another. To beat the competition, they have to offer better. A stronger front end, and the 6.0 would be, gasp, innovative, and would bruise the competition badly. A V6 Dmax would be even better than that.

So the H3 Alpha gets a few inches longer. It gets a mile or two less per mpg. It'll need an HD frontend. You'd have to pay a few more thousand. Wanna bet me how many people on this forum woud jump TOMORROW if it were to come out with the 6.0 or V6 Dmax!?!

[RuggedH2]

I would. Tomorrow. Be damn happy to.:D

[usetosellhummer]

comparing a full size GMC to the H3 is stupid:twak:

[RuggedH2]

Maybe, but big torque is good.

I love my truck, I don't complain about it, I'm not bitchin.

But if they come out with a V8, I'm getting one.

[marin8703]

the need of power is in the foot of the beholder.:D There really isnt a point to a big engine if you dont really need it. I personally need just a tiny bit more power for towing, but i still got the H3 cauze it outshines most of the more powerfull trucks in almost every other aspect. Im still loving it, but if something more comes out in the h3, i might think about upgrading.

[PARAGON]

comparing a full size GMC to the H3 is stupid:twak:WHAT? It's all a matter of power vs. weight.

Sounds like your talkin' about a H2:fdance: :jump:

If you look at the numbers comparing a I6 Envoy to a V8 Envoy Denali, mpg is almost identical.

[Huck BB62]

If you look at the numbers comparing a I6 Envoy to a V8 Envoy Denali, mpg is almost identical.

Not really, the H2 needs an upgrade too. It needs more power because it's heavier'n hell and has the aerodynamics of a billboard. I've read over and over about H2s being upgraded with superchargers and now Dmax engines. Now why would they do that?

They are putting 6.0s in H3s, but I'd bet my hiking boots that they rest of the drivetrain wouldn't survive ten minute with it on the trail.

I read an article in Diesel Power Magazine where a guy put a Cummins in a new Power Wagon. If he seriously offroads it, he's gonna kill axle parts because they simply aren't rated for it.

It's gotta be a package. The H3 is marketed as a serious offroading machine. When people do that, they bust 'em. You can be careful and help out the situation, but the Alpha needs to be built. One look above, and you can see the eagerness for it. I want it. I don't want a heep (won't be getting one either) Don't want to put a Powerwagon on the trails here (toooooo big) I love our H3, it just needs a little upgrade to be perfect.

When/if the H3 V8 Alpha Adventure comes out, there's going to be a LOT of used H3s available so you folks that think they're perfect will be ecstatic!

[KCJohn]

Ok just get out your checkbook. You guys who just gotta have more power can have it today, providing you are willing to put your money where your mouth is, and in some cases that would be QUITE a WAD of cash.

Don't know anything other than what the web site says.... but there you are!:eek:

[Viet Nam Vette]

$15..Large.... :cool:

[Huck BB62]

Yeah, that'd work how? Just how many ways to blow up other parts. It needs to be part of a package otherwise it'd make as much sense as bolting a JATO rocket on the roof.

[H3.007]

I just looked at the specs for a 2007 Yukon. Isn't that a heavier vehicle than the H3? If so, it is getting comparable gas mileage with a V8 and obviously more horses....:rant:

And would such a comparison be stupid? :popcorn:

[Steve - SanJose]

If only the real world gas mileage of the Yukon was even close to the EPA mpg numbers. Everything I've seen so far indicates mileage around 12mpg.

[JAYB1RD]

What's wrong with the H3 drivetrain behind a V8? The rear axle is just a narrowed version of the 1/2ton pickup 10 bolt. The 4L60E trans. is what goes in the same trucks behind many 5.3L and 5.L7 V8s from the factory. The transfer case I admitedly don't know much about, but it looks VERY similar to the auto-trac transfercase which is also found in many fullsize 4WD GM trucks. That leaves the front axle as (IMO) the only part that isn't up to V8 power standards. Now, GM used to make a cast iron version of the mid-size IFS axle (I think it was the ZR2 S10), so I would venture to guess the H3 Alpha would have this as well.

In short, an H3 Alpha only needs a 5.3L V8 and a cast iron, locking, front diff in addition to the currrent H3 Adventure components to be a reality. If they want to throw in a body lift to clear the engine some more and maybe fit 35s, all the better ;)

[blindzebra]

I agree a 1 inch body lift with 35s would be my ideal H3. I love the articulation and that wouldn't change it abit. I would also say the alpha should come with the HPN shocks. All that and above, Good lord that would be one incredible stock vehicle.

[H3.007]

I'd be more than happy to let them use mine as a real world test vehicle :jump:

[stagger_lee]

I am completely happy now with what I have. Unfortunately I am a chop aholic. If I keep the H3 for a long term rig which could very well will be the case, I definatley with play with the engine swap idea and 4 linked Dana 60s or ford 9"s front and rear. Not till after the car is done for, and starts to fall apart on its own, and considering the way we take care of our vehicles, wont be for a long time. I love my H3! :perfect10s: :beerchug:

It's all a matter of power vs. weight.


Para, that's just what confounds me.

The H2: 325 HP (@5,600 rmp)/6,400 lbs = 1 HP/19.69 lbs

The H3: 242 HP (@5,200 rmp)/4,700 lbs = 1 HP/19.42 lbs

Thus, if these numbers are correct, the H3 is about 1.4% more powerful than the H2 per weight carried. If you add the same equal weight, say 500 lbs, of people and cargo, to each vehicle, this does favor the H2, a little, but the ratio then becomes 1/21.23 for the H2 vs. 1/21.49 for the H3, which is only a 2.1% advantage in power/weight for the H2.

Is the reason the H3 is/seems less powerful because of the higher rpms required of the I5 or something else?

You said a mouthful but you left out the most important factor - Torque. While HP is how quickly you can get "work" done, Torque states how much you can do.

I understand, but I thought that the H3 can get the work done, it just takes it more time (i.e. slower acceleration) than some desire.

It's because of the difference in torque curves.

The H3 peak torque is at around 4000rpm I believe. My old truck has just 210hp, but is much stronger than the 3.7L H3 off the line because its peak 300ft lbs come in at 1800rpm. Both trucks weigh comparably the same and have 33" tires, but the old chevy 5.7L has much more grunt, at every rpm, even though it only has 3.42 gearing!

Don't get me wrong, I think the H3 power is plenty adequete as it is. It can still get you in some trouble with the law enforcement officers if you want, but you just have to keep the revs over 3000rpm to get them to notice you. That's just the nature of a small inline engine. The I5 makes a great base engine, but an optional V8 with more low-end grunt would go over very well with just about everyone.

Nice to see someone bring up the torque talk. I know from experience, my Dodge Dakota Quad Cab with the 4.7 V8 was a rocket, especially compared to my H3. But when it came to towing, my H3 would out pull my Dakota towing 4,400 lbs of Samurai on a 14 foot trailer up Ice House Road and to Moab getting better mileage at the same time. Torque is where it's at! Sure, I wish my H3 would take off the line like my Dakota did and I really wished it could pass like my Dodge, but it can't. I just got used to it. And for the record, I would trade in and pay more for a V8 option.

The H3's peak torque is at 2800RPM.

Vortec 3.7L I-5 inline five cylinder with 242 horsepower (180 kW) at 5600 rpm* and 242 lb ft. of torque (328 Nm) at 4600 rpm*

A number of sites say the 3.7L peaks at 4600rpm. A more thorough search than trying to remember off the top of my head returns the 2800rpm specification as well, but seems to be tied to the 3.5L. And that may be true, as the 3.7L might just build off of that number on it's way to 4600rpm, making for a pretty flat torqe curve. Unlikely though, considering how much harder the engine pulls over 4000rpm. Of course, one website said the HP and torque values were EACH less than 150!! I will have to do some more digging later.

The H3's peak torque is at 2800RPM.

My QUEEN...

is that for the 3.5, or the 3.7 or the V-8 ???

[Steve - SanJose]

Not a response from HB. But the answer is 3.5L.

[3Hummer]

I was just reading on the Hummer website about the H1 Alpha and it said "dont think the Alpha is limited to the H1, it will be a line of top end Hummers that will be fused into the h2, SUT and H3" quote my be a little off in wording but thats just about what it said

Correct Blingy Steve :D

Sorry, I was in Cupertino all day.

[pteam]

yea yea just like it was gonna come with a v8. then it was getting a v8 and it got a 3.7 insted now its another v8 rumor. I seriously doubt you will ever see a v8 in it. It doesnt even have a 6. Im sure your chances of a 6 are far better.

Guess that point is moot. :giggling:
