True, but think of how much HP and TQ you could have from a motor a third as big... It'd still be more than most people, even heavy towers, really need, and it'd give you great mileage.
Strip off all the EPA crap, and you have a vehicle that gets 3-4MPG better. At what point does the value of diminishing returns start to negate the positive effects of exhaust cleaning equipment?

Yeah I'm afraid for GM. They are by far in the worst situation. They did not heed the call to reform their organisation, and now they have been paying $67million/day for it.
Getting back to the big 3 of diesels, I used to be a massive Powerstroke fan. When the 7.3L came out, I was sold for life...The Cummins was nice, but Dodges just had too many tranny problems. And GM at the time, was not even in the picture. My how things have changed...
What is also cool is the fact that the new 4.5L duramax has the same power figures that the '01-'04 Duramax's had; 300hp and 520ft-lbs. Not too shabby for a 2.1L smaller displacement!!! Except with those smaller cylinders, it won't have nearly the same power potential, or a badass exhaust tune. BUT...economy.

Not to bash on you or what you think, but the duramax block, heads, cranks, ect ect are made over seas by Isusu Asia. They are shipped in rough cast on big pallets to the U.S. and then finish machined and assembled here in America. Now to me that makes it a joint effort between Isuzu and GM, thats not to say it isnt still a great engine just that its not soley made by GM.
Exactly, except Cummins passed 2010 tests in 2007, meanwhile Izusu and Navistar waited until the last minute (so to speak) to come out with a production engine that can handle it.
As far as the new 6.9L goes, it makes 425HP at this point, and its not even out yet, so why are you bench racing it already? You have another 6-10 months before this thing hits showroom floors. It could be tuned to 390HP by then, or lower, or higher. I know what they produced in testing, I wasn't asking you to give me answers. But the 2010 Engine isn't Stock yet is it, hence the term "Prototype." I either misunderstood what you were saying, or we both misunderstood each other. As far as Pro-Mod parts and technology goes, I don't understand why you even said this. Pro-Mod parts? If they are stock, they aren't "Pro-Mod". They may have been 5 years ago, but thats the point of racing, to develop better parts for the OEM. Formula 1, Le Mans, Indy, they all work this way, and the diesel world is no different. Technology is right about equal between all 3 engine manufacturers, but do you really think pumping computers into engines is a good thing? I sure as hell don't. There is no question the tried and true 12V is the king of reliability, and can produce the most horsepower out of any of the engines when built to the hilt. It does it without a computer, granted its not often streetable power, but either are most 1000HP+ D-Max's or CR Dodges running numerous computer programs and dozens of sensors.
In either case, the world of great diesel engines is here to stay, at least for the next few decades, lets celebrate

Isuzu ? where did you get that, isuzu had nothing to do with the LMM. Gm owns 100% of Dmax . Isuzu and GM worked together to come up with the initial deign of the first dmax, it was a joint effort.Isuzu is not involved ,or has no ownership in DMAX.
