In the Diesel Power mag there is a short non informative article on a speculation to when there might be a GMT1000 platform and such, then the mention the Rumored "6.9L UMAX Diesel" anyone know anything about what they are talking about? I think a 6.9 would be interesting but whats a UMAX typo? or predecessor to the DMAX

Interesting. I just got my issue in the mail. I'll be taking a look.

You know what comes to mind - since in 2010 urea injection is supposed to start, maybe UMAX is short for UreaMax :D (sorry, couldn't resist)

But seriously, it sounds like it's probably just a typo. There is a company named Umax that makes scanners. Infact, my very first scanner was made by Umax. I still have that old parallel port flatbed scanner laying around, about eight years old now.

6.9L... sounds like a bored Duramax!

Do you mean the International engine im sure you didnt but look

I saw them mention UMAX aswell. I'm guessing typo myself. Lots of info on Bio in this issue. Almost need to be a chemist to decipher some of it.

i dont know about the 6.9 but i read somewhere that there will be a new d-max called the umax(ultra max)

I saw the same thing last night

who said the next series was going to be the GMT-1000...?

I suppose Diesel Power also thinks the 88-98 trucks were called the GMT-700's too. :rolleyes: (they were actually called the GMT-400's)

As ive said before, my own guess is just as good as any magazines "sources". Its still 3 years away and no word from the General, who would know best about this. ;)

i think this is just speculation it is just like there was talk of a 7.4L d-max awhile back and that didn't go in our trucks

Thanks for the link. Now I know why my 86 f250 6.9 was stolen when it had 450,000 mi on it. It is probably still going

What does "gmt" stand for?

General... Motors... Truck... maybe?

450K, Alot of miles...

Theres been so much sucess with the 6.6, why change to a 6.9??

Strict Emmissions Testing

the new one being designed does have something to do with the use of urea, but can't remember exactly what it was.

It will all involve SCR. ( Selective Catylitic reduction. ) Urea will somehow be introduced into the system ( fuel? ) it will have an onboard tank, and will limp if emptied and wil limp untill refiled.

Only time will tell.

I think it's injected into the exhaust to neutralize the nox particles somehow. From what I've read about it the effect on mileage should be next to none.

I don't know how the urea will work, but if Dodge's Cummins is already compliant with their 6.7, GM will have a hard sell if they have to use something totally different than the competition. I hope the urea usage is just a rumor and nothing set in concrete, I won't buy a diesel that I have to add additional liquids other than diesel to run. If Cummins can do it without urea, GM should as well, and if not, GM's sell in their HD trucks will suffer. Surely I'm not the only one that is thinking this. If Dodge's new 6 speed auto holds up and their new interior design people put a nicer interior in the Ram, it'll really be a tough truck to not buy.

On a side note, GM's new smaller emission compliant diesels likely to go in the 1/2 Tons don't make mention of urea injection, surely GM will design something with larger cubes and more power that's emission compliant with just a DPF. Chris

Exactly

is daimler/chrysler using urea now in there bluetech diesels?

The 7.4 Duramax (Built in Japan by Isuzu) is an inline 6-cylinder used in medium duty applications.

Don't crap on the urea idea, urea (SCR) cleans the emissions up after the engine, no need to hamper the engine with the retarded timing and post injection events to "light up" a DPF. Why use diesel fuel to control emissions when you can use something else (not foreign). DCX uses it (along with a lot of others) in Europe and there is no fuel mileage hit. Make the engine as efficient as possible and clean it up after!

I believe so. IIRC, a M-B sedan with the diesel is going to incorporate the urea injection with the emission system.

I sat through a learning conference on diesel exhaust treatment technologies one day at work sponsored by SAE. One of the speakers was a guy from GM that heads the diesel engine development (I can't remember his exact title). He spoke about urea treatment vs the other technologies. He mentioned that the urea systems don't have the negative impact on fuel economy as the systems that require high temperatures to regenerate. When questioned if GM was developing a urea system for diesel engines, he would refuse to answer.

So urea injection is actually going to be in place of a DPF, rather than in addition to it?

Didn't know that.So UMAX, I guess ureamax is a good guess. The I-6 dmax is a 7.8

I get diesel power too, and I enjoy reading the magizene. But they dont have the best sources for their information sometimes. There is no way in hell that GM would release a GMT1000 or similar in 2010. That is only 3 years off. Most likely, this new body style has until 2014 or longer. GMT 800 ran for what, 9 years? 98-2007?

That little blurb about the 6.7l cummins only refers to the 305 hp version in the chassis cab. And no where did they say anything about NOT using Urea Injection. I would be smart for DCX to use the Bluetec name with the
Cummins, seeing that they will license the technology and name to VW/Audi and BMW for use in their diesels. The centerpiece of the Bluetec will be the Urea injection. Honestly, I think that Urea injection will be just like refilling the windshield washer canister, another mundane thing. The Urea injection will also have variable life spans, as it is injected mostly under high load conditions, where cylinder pressure and temp are highest.

Honestly, all of this emmissions crap for the 07.5 vehicles is really killing the market. The diesel engine option went up $1,100 in GM's and $1,500 in fords. That just makes an expensive engine even more so. All of these sensors and electronics will fail at a pretty high rate for the first couple of years as well. Makes me glad that I got an 2006.

Wonder if you could piss in your tank to refill? ):h

My '06 LBZ looks better all the time 11000 mi., NO problems at all, also pull a RV trailer. Ya gotta love it !!!:driver:

well a couple months back in diesel power they said that the duramax might not be anymore because of the emission changes in 2010. So the lmm might be the last "duramax"..:(

Why don't we wait and see. GM is not that stupid. Something is being worked on for sure. Oh yea, take it FWIW, remember you read it in a magazine.

Hmm. maybe I forgot to mention It was under the "Detroit Spy Report" section. which as everyone knows is 50/50 anyways
