Didn't GM just use their gas engine to make the diesel? I not sure how they were able to get the compression ratio up enough to make it even work.

That's the case with all diesel engines and this same argument was used back when I picked up my first 7.3 in '99 and Diesel was $0.97 a gallon and always $0.10 less than Regular Unleaded!

it wil out run your ford!!!

Maybe true if Ford had a little diesel.

FWIW, went to the local Dodge dealership. You might have felt the earth shift a little just before lunch yesterday? Anyway, they told me they can start taking orders for this diesel until the 7th of January. I test drove the Jeep Grand Cherokee with the EcoDiesel and I must say for a small diesel it had some impressive power. But then again it wasn't towing 8-10K.

Why would some use that when diesel was cheaper?

Because at the time it was a $5,000 up-charge for the Powerstroke? I guess everything is relative and when someone doesn't get how addictive diesels with turbos are they cannot justify the extra money in their mind? Just a guess, because that was never my argument.

Nice truck, big $

Interesting read.

I think Fiat/Chrysler really messed up by letting nissan get their hands on the 5.0L Cummins. This little V6 is underpowered for that size of a truck. Well maybe the single cab short box, but throw a family with clothes and a boat/camper hooked up behind it(4 door), and that sixer is maxed out. 8 speed trans is great for keeping the engine in its power band at all times. How does it stay there, constant shifting, one clutch releasing and one grabbing, all under load. It just sounds like a lot of unnessecery shift up shift down. Id sacrifice 2 mpg for a 6 speed and a 5.0 Cummins. I think ill keep my old 12 valve with the manual transmission. That way Ill decide when it shifts.

Currently diesel powers some 60 percent of the vehicles in Europe, where the fuel is less expensive than highly taxed gasoline. In the U.S. diesel typically costs between 25 cents and 40 cents per gallon more than gasoline, but the difference has been trending downward the past couple of years, according to Allen Schaeffer, executive director of the Diesel Technology Forum. When factoring in diesel’s relatively higher fuel efficiency, he says the cost differential is less significant.

This is something I cannot understand, when I picked up my first diesel the price of fuel was $0.10 less then Regular Unleaded. I have heard it is because the EPA changed the diesel fuel requirements, but I personally think it has to due with the 'commercial' demands and not the EPA since the price shifted after the Katrina spike, and it hasn't adjusted since. Was this a matter of timing with new fuel standards, who knows.

Something else about this article, I was looking very hard at the Jetta TDi several years ago and was told by our local VW dealership is that there are only so many TDi engines per year they [VW] are allowed to sell. REALLY?! So, let me get this straight, as a nation we consume too much fuel and oil, a [German] manufacture comes out with an extremely fuel efficient engine that would cut consumption and there is a limited amount of units that can be sold. One word, Lobbyist.
