V8 H3 Alpha
 

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?

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

Dream on about the V8...

Re: V8 H3 Alpha
 

you might not know yet

Re: V8 H3 Alpha
 

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.

Here we go again...someone heard someone else say that they in turn heard someone else say, or the infamous, "the dealer said so."

I stripper friend of mine has a sister, who's baby daddy heard from his girlfriends momma's pimp that it's gonna come with 26 inch rims and
a 50 inch plasma in the back.;)

Re: V8 H3 Alpha
 

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

Re: V8 H3 Alpha
 

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

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

OK

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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.



Drive what you need ... Need what you drive..:OWNED:

Nice!!!!!!:beerchug:

Re: V8 H3 Alpha
 

Thanks Dude...:beerchug:

Re: V8 H3 Alpha
 

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...

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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

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

Re: V8 H3 Alpha
 

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?

Re: V8 H3 Alpha
 

that's the part that has me skeered

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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
:jump:

Re: V8 H3 Alpha
 

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...

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

lmao :beerchug: :giggling:

Re: V8 H3 Alpha
 

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


thanks,

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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,
spencer

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

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

Re: V8 H3 Alpha
 

I wish it was that simple....

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

ditto....

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.

Re: V8 H3 Alpha
 

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

Re: V8 H3 Alpha
 

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.

Re: V8 H3 Alpha
 

agreed....

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