GM Cancels 29mpg 4.5L Diesel Engine

[RACER X]

or maybe they over exagerated their feat and are getting out before getting called out on it.

That would be suspicion #1 for me.

#2 would be that it can't meet emissions standards as is.

#3, it can meet current emissions standards but it is close to the limit, and with states now reassured in their ability to set their own standards, tougher than the Fed's, GM doesn't think they will be able to sell it in enough states.

#4, it meets or exceeds all performance goals and runs clean as hell, but will be so damn expensive GM doesn't think they can sell it.

#5, it is a super-engine that can do everything, but GM is planning to close the factories capable of producing the engine and projected volume of this motor alone isn't enough to justify keeping any of the factories open.

Wrong, Wrong, Wrong Wrong and Wrong. The engine was dropped because they were told to do so or moreso that the truck/SUV plants were the ones that should close. It was a trick engine...no exhaust manifolds and the turbo was in the center between the intake manifolds.

It was a 2010 calendar year complaint engine.

Its a damn shame.

Isn't that kind of what I said for #5?

Even though I listed it I still view it as a remote possibility. GM is not closing every truck plant. Even if trucks and SUVs die as passenger vehicles there will still be a demand for trucks, and consequently a need to build trucks for the commercial market. I think the commercial market buys a hell of a lot more diesel trucks than the passenger market, meaning the engine would still be viable. That is unless it isn't too expensive or can't meet emissions.

IMO it's getting killed because the costs to put it in production will not be recovered at the price and quantity that is estimated to be sold at least in the near term, and they can OEM an equevelent engine from someone else for a lot less money. In the past they'd pony up the development costs, I'd bet there's have been some long meetings going over list of projects looking for projects to cut.
