I heard from a local dealer the projected diesel for the JK is going to be an inline 6cyl. This dealer also told me one of these diesel JKs is being test driven in my town right now! I'm not a very good judge of character, but this is the exact kind of thing I want to hear, therefor, I will believe it.

 

Wasn't one of the reasons Jeep got rid of inline 6 that it didn't fit under the hood anymore...

 

The 4.0 inline 6 was replaced due to not meeting the 2007 smog standards. Papabear

 

if they are out test driving around a town doesnt that imply that they have met the emmission standards? if so wouldnt that mean that the rumored 2010 dielel date might be pushed up?

 

With all the room under the hood and the larger dimensions of the JK, an inline 6 HAS to fit. That's just my speculation. He gave me more info on it, such as Liters and all that. But of course, like a picture of Bigfoot, I forgot to listen and don't remember what it was.

Emissions doesn't have much to do with it, though it does in a sense. It's the new fuel these low emission diesels run on that is keeping them out of production. The fuel isn't widely available yet, and "regular" diesel will burn them up. I'm sure this Jeep is fueling up out of a storage tank or truck somewhere here.

One thing that makes this rumor plausible is that I live in Charlottesville, Va: The place where the Insurance Institute for Highway Safety (IIHS) is located. In case you don't know, that is where they crash test all the cars to get the ratings. I would almost bet you a steak dinner the fuel is kept there and probably being driven by an engineer. Can someone say, "Midnight ops to the IIHS building?"

Just as a disclaimer, before I get berated over this too much, it is all hearsay and speculation. I do not know if this is true, but wouldn't it be cool?

 

Of course it would be cool. And I think plausable. SEMA had a JK with a MB diesel in it right? And just this evening I saw a MB ML diesel with a "Low Sulfur Diesel Only" sticker on the dash. Here is hoping

 

Ok, let's say it is true, and I end up buying one. Not to sound negative, but what are the odds that a tiny gas station in the middle of nowhere is going to have the fuel I will need? :confused:

 

I agree, the extra torque and range are great benifits but finding a station may be a pain in the tank, small "fuel" stations in the desert or any outskirt area are not likley to have basic Diesel much less Low Sulfur Diesel

there may be a time in the future that Diesel is available everywere Gas is but now you have to travel to europe for it to be that common

 

ULSD fuel is already being fanned out to stations across the country. It wouldn't be too hard to find one I don't think. I figure by '08 it'll be hard to find a diesel pump that isn't ULSD. We've got more diesel trucks here in TX than in most parts of the country though, so that may factor into the availability of diesel in general, and USLD here. There's probably a half dozen or more stations within 3 miles of my house that carry diesel.

Personally I doubt the JK would get an I6 diesel motor. I think the new ones being developed by Cummins will be too heavy, and MB uses V6 motors (ie: the 3.0L Bluetec in that SEMA JK).

 

On June 1 of this year, refiners were required to begin producing 80% of their annual output of diesel as ULSD. On October 15 it became available at retail. By the time these engines are released by the auto manufacturers, the diesel will be easily obtainable.

As for older diesel engines not built for ULSD, the "Good Ol' Stuff" will still be available for at least a few years. I haven't found a definite number. But, sources are saying that if Biodiesel is mixed with ULSD the lubricating properties of Biodiesel will meet the standards of the older engines.

The downside to ULSD is power loss. The numbers are saying a noticeable 1% degradation in power. This lack of power is expected to effect MPG in a bad way. You know what I say about this? "Build a bigger diesel!!"

Jeepin Jason, my whole family will be without transportation if the "old diesel" is dissolved. I'm the only one in my family that doesn't live in Tx right now, and I'm the only one that doesn't drive a diesel--including my mom-->1 ton 4wd Dodge...but it's a girlie Dodge with an automatic.

Did you also know that Texas is the largest carbon emitting state in the country? And TXU is preparing to build 11 new coal burning power plants. Gov. Rick Perry is pushing to speed up the permit process before the new stricter federal laws go into effect. Good luck with that emphysema!
