Builder...new engine options?

[canucksnaphook]

Just curious if there are any discussions about a new turbo for the I5?? I have heard very positive things about the current power so why are people so stuck on numbers? Thanks

theres a link on my site to a Q and A w/ susan docherty, she's the marketing GM of Hummer and she talks about a possible 'alpha' H3...

[canucksnaphook]

a diesel in a H3 ?? I think I would love that combination or even the turbo? What a life this could be.....

thanks Hummer Guy

[H3 Builder]

I believe from what I have heard that the diesel will only be in the H3'3 built in Africa. I don't think you will see the factory turbo, either. South Africa has a contract to build 13,000 a year for 6 years, and our plant will be suppling them with a lot of assemblies for them. North American content will be ruffly 80-85 percent.

Love her statement, "Hummer doesn't own XM." GM doesn't own XM either. http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

It's in the Press section in this forum, and to actually point to an answer to the question. She suggests that the turbo is still in the works and a very good possibility.

[jp's-h3]

I've read a couple of articles that say there might be a 3.7 I-5 and poss a v-8.

I would prefer a supercharger for more low-end torque. I have heard rumors about the 5.3L V8, displacement on demand, that is currently in some mid-sized cars.

same plant...same engine? every other car basiclly has an SS why not the colorado? and why you're there just drop an LS2 in the H3

[Wild One]

A Corvette engine in an H3? Sweeter than a lover's kiss, hot damn!

ahh the replacement cyclone and typhoon..... it's a shame they'll never make it. http://www.elcova.com/infopop/emoticons/icon_frown.gif

That is funny, I was just thinking about both of those earlier today.

[Matt5462]

Is there such a thing has having to much engine in a hummer this size?? Isn't it designned for a smaller engine to match its weight to power/torq ratio?? I haven't done much 4wheeling yet, but isn't the idea to use low rpms and crawl. What would the advantages really be

[HummerNewbie]

Not sure there would be any advantage off-road but it sure would be nice if you could have the best of both worlds http://www.elcova.com/infopop/emoticons/icon_biggrin.gif

Don't know if that is really possible though http://www.elcova.com/infopop/emoticons/icon_frown.gif

[f5fstop]

From looking under the hood, whatever they do cannot extend much farther forward. That is one reason why I believe they did not go to the 275 hp I6 (same as the I5, but missing one cylinder).

Remember GM is running a business. They have to meet many goals (which are moving targets)before things like engine upgrades are woven into production. The H3's acceleration performance is on par with the H2's.

One problem is that magazines have to write What's hot and What's not. If the H3's acceleration was on par with the upper end SUV, they would still find something to complain about. I've done some research to see how the H3 actaully compares to a wide variety of vehicles. Here are some 0 - 60 MPH time (data from various published magazine tests):

H3 - 10.2 sec.
Ford Expedition - 10.5 sec.
Dodge Ram quad cab - 10.2 sec.
Land Rover Freelander - 10.6 sec.
Toyota Sienna - 10.1 sec.
Toyota RAV 4 - 10.9 sec.
Toyota 4Runner - 10.4 sec.
Buick Rendezvous - 11.4
Chrysler PT Cruiser - 11.6 sec.
Nissan Xterra - 11.5 sec.
Ford Escape XLT Sport - 10.6 sec.
Hummer H2 - 10.2 sec.
Jeep Liberty - 10.1 sec.
Subaru Outback - 11.8
Volkswagen Passat - 11.5
Dodge Stratus - 10.4
Mazda MPV - 10.0
Mitsbuishi Outlander - 11.6
Subaru Baja - 10.7
Subaru Legacy - 10.9
Volkswagen Jetta - 14.0
Subaru Imprezza - 10.0
Dodge Caravan - 11.4
Chevy Venture - 11.0
Jeep Grand Cherokee - 10.1
Nissan Sentra - 10.9
Ford Excursion - 9.7
Nissan Altima - 9.8

There are many more to this list.

If you read the mags the acceleration is so severe you'll never be able to merge on a highway and the H3 is all-so-slow. Look at the reviews for Ford Expedition and see if the acceleration was mentioned in the What's not.

[Wild One]

My beef with the wimpy 220hp engine is indeed relative. In a world of Hemi powered Jeeps and fast cars, the pokiness of the H3 is not good. Sure, not much out-of-the-box will beat its off-road prowess, but most off-road destinations require a lot of on-road travel, so street performance IS important.

One of the cheapest SUVs today, the 2005 Xterra, sports a 265hp engine, that can propel the X from 0-60 in 6.5 seconds. While I don't expect any Hummer to offer numbers like that, it would be nice to see the H3 move from the bottom of the pack in acceleration to somewhere in the middle.

I love the H3, its engineering, its exterior design, its terrific interior, but it's just that engine that keeps me from signing up for one. I'm not interested in the high-power forced induction Alpha version of the H3, I just want a better powerplant that can motivate 4700 pounds of Hummer confidently in traffic.

[bender]

power is over-rated imo. i came from a 333HP BMW M3 friggin rocket that was not much slower 0-60 than a ferrari 360 modena (i got ~4.8 sec 0-60). you know what? i wanted more power since i got so used to it. you can't get much better than 4.8 sec unless you go exotic. i'm plenty happy with the H3's power. i didn't buy it for stop light racing!!! it merges on the highway just fine.

[bparker]

I totally agree Bender, I traded in my 03 Z06 Corvette when I bought my H3 and some people with small penis seem to think they need to be top dawg red light to red light.

Horsepower isn't just about the ability to race away from stop lights or make up for a "small penis". Horsepower helps move you past a slow semi-trailer up a 6-percent grade. Horsepower allows you to carry family, luggage, and a dog up winding hilly roads to Grandma's house and keep the air conditioning on.

Maybe you guys live in flat parts of the country, but around where I live and travel, there are lots of hills and long streches of highway are 6-percent grade. Like I said, I'm not asking for a high-powered H3, I just want something to keep up with traffic; Something with just average acceleration would be fine, as long as it has a giant sunroof like an H3, and the great interior of the H3. Hopefully, the 3.7L will be that.

[Georgemarc]

I am in a flat part of texas, so, I guess that is why I amjust fine with my H3 acceration capabilities

[Hummer Guy]

6 percent grade isn't that much compared to the 60 percent grade it can handle...

No, I saw them, some of the numbers reflect old model years and the smallest engine options. The H3 is coming into a world of Hemi-powered Jeeps, 265HP 6-spd Xterras...the new Toyota FJ Cruiser even has 6-speeds (7 if you count reverse, ha-ha) and 245HP.

For its price and class, nothing will beat an H3 off-road, but unless you live in a remote survivalist compound, most of your driving is on-road, so good on-road performance is important, at least to me.

I love nearly everything about the H3, my only beef with it is the engine power.

[timgco]

I just got back from a trip to Breckenridge CO. I took the H3 up and back with no issues of power. Yes you have to floor it to keep above 70 in a few spots, but that's no different than my SUT. I think that another 60HP would be about perfect; and I think you can get closer to that by adding exhaust, air intake, and power programmer. Getting into traffic isn't an issue, but does take some getting used to.

The data was taken over the past 3 years. Some were smaller engines some weren't - I just took the data that was available. I wanted to address my fellow magazine writers' attack on the H3's power.

A new intake, new exhaust, and programming will take you to 250-260 HP. I heard that LS2 edit includes the H3 - I haven't verified this yet. If you know what you are doing you can optimize 87 octane tuning for torque and power as well as get better fuel econony (and lower emissions). The tranny shift points and line pressure could you some tweaking too.

The issue with a new air box is that the MAF is integrated with the stock box. This leaves only a filter and lid as an economical air box mod.

I write for my nic and I plan on doing some product testing on the H3. I'm starting to get some parts to test now.
