Hummer H2: A diesel-powered Alpha performance model could arrive in 2007.

Hummer H3: The H3 is scheduled to get an Alpha model in 2007. It will be powered by either a Turbocharged I-5 or V8.

Hummer H4/HX: The HX will be Hummer’s competitor for the Jeep Wrangler. It will be based on the Theta platform and will have a removable top and doors. It will also be the cheapest vehicle in the Hummer line-up, starting in the mid $20,000’s. It may arrive in 2007

 

Hummer Truck: GM has said in the past that they think a pickup truck would fit into the Hummer lineup. Expect to see one based on the H3T concept sometime in 2008.

 

How sure are we that the 07 will have the bigger engine? I hear different stories. I am working on ordering an 06 and drove it already - the power was not great but I think I can live with it. However, I would hate to buy a 40k H3 only to find that no one is interested in it once the larger engine comes out. In other words, won't the value of the 'weaker' H3's dramatically decrease? And wouln't GM want to avoid that?

 

i think it'll be fine. After all lots of cars/trucks are offered with different engines and even though this gas mileage is not really great. the biggen motor will get even worse mileage. And there will always be lots of people who choose mileage over power.

 

This information was copied from another Hummer Forum...The author seems to be very knowledgable and has a source of good inside information.

" The 2007 H3 will still have only one engine option, but it will be a 3.7L not the 3.5L that is offered on the '06. It will have approx. 25 more HP (not sure of SAE rating at this time, could be up to 30 more HP.
The 5.3L V8 will not be out until '08, unless testing is finished before and launched after January as a mid-'07 model, but honestly, don't look for one until '08 since it is still in testing stage. It might also be connected to a new transmission, but not confirmed if production would be available for this trans.
The diesel probably will never make it to the states, that is still way up in the air. Marketing sees no reason for a diesel in the states. The Isuzu is used for European and export from South Africa's plant."

 

Good info, do you happen to know if it'll be a 6 or still 5 cylinder?

I don't see why some americans are getting all excited about diesels. The only reason europeans drive em is because diesel is cheaper. Gas is still so cheap in america that I too dont see a reason to introduce a diesel in the states.
Is anyone here more interested in a diesel than gas?

 

I would be more than interested in a Diesel..Because of the better torque for one thing..The US is in the process of re-doing all the refineries to produce the low sulfur diesel fuel like Europe and abroad (that's their excuse for the higher than normal diesel fuel prices right now).. also the Bio-diesel fuel is just around the corner too for mass production..So YES, an H3 diesel would be awesome!!

 

You get more mile per gallon on Diesel

 

Unless I misunderstood my sources in the fuel storage and refining business, the biggest problem with biodiesel is that it requires more energy to refine it then what you can potentially get out of it. Even the vegitable oil that people get from thier favorite fast food/ oreintal food place requires either heating up to reduce its viscosity, or chemically altering it to reduce its viscosity; this is above the cost of filtering out all of the food particles. Either way, it still isn't as cost effective as petrolium diesel, although it does burn cleaner and is a renewable source. The ultra low sulfer fuel, as far as I understand, is run through a finer filter when hot to remove the extra sulfer. Although this does add a small increase in cost of refining, the biggest delay in that is getting enough engines out there that can safely burn it. It is my understanding that the ultra low causes higher combustion tempretures which in turn cause the engine to run hotter. Also, with catylatic converters being put on light diesel vehicles, the sulfer will plug them up.
As kind of a heads up in the diesel engine world, all semi trucks manufatured as a 2005 or newer must now have an "ultra low emissions" engine. What this has meant to most of the engine manufaturers is that they have now added an EGR system to them, just like what is in your car. This has created higher purchasing cost and operating temps as well, but counteracted with a bigger radiator. These requirements technology will eventually be brought down into the light duty world as well.
One final note, all gasoline from the major refineries is now ultra low sulfer as well. The smaller refineries will be following soon. I bet you didn't even know sulfer was in gas. I didn't and I deliver it

 

Good Info Linus..but correct me if I'm wrong...but Bio-diesel use to be what the first diesels used before there was petrol diesel fuel...so the technology is pretty old...And I've read or understand that in the southern hemisphere of the world the majority or at least a lot of the diesel fuels are in fact now Bio-diesel....So I believe it is the petroleum industry that is making all the excuses for not coming on line sooner with this type of fuel..just like ethanol...After all, they wouldn't want a farmer from Poedunk Iowa making more money than J.Paul Getty did.
