It was going to be an amazing engine and totally change the market.

    I was just thinking we have enough people on this site with contacts in GM that could ask about it. The engine from my understanding is ready to launch and was fully developed before being shelved.

    There is almost 0 info about their new engine... At least when you look up 4.5L duramax you find lots of info.
    Yeah, but then again, how much info is out about the engine in the new Vette? lol. The engine they are going to put in the Ram is the same one that is going into the Grand Cherokee (240hp and 420ft. lbs of torque according to NY Times). And from what I read elsewhere, they will offer the same engine with more power for the Ram. I do wish they woulda dropped that 4.5 Dmax into the NNBS. That woulda been awesome.

    Maybe if were lucky GM is just letting Dodge do all the market surveying for them and they'll get into the act in the next model year or two.
    Unfortunately when optioned with a Diesel the price of a truck climbs quickly so this may be one reason GM is holding off, with the economy still at issue most people wont spend the extra money for a Diesel right now.
