SteveCA said:I spoke to a GM Commercial Vehicle Muckie muck at SEMA two weeks ago and learned the following;
The full size vans will get the motor in 2005 (2006 model year), it will not have the Allison, but a 4L80E. My conclusion is a detuned or smaller Duramax.
The Suburban 2500's will get the duramax several years later, perhaps 2008, again with the 4L80E as the Allsion won't fit. Same conclusion, smaller or detuned Duramax.
The yukons and tahoes are unlikely to get the motors as they are half ton chassis' and not "heavy Duty"
Having said all that, I think GM will have to rethink their strategy when the new VW Diesel hits the SUV market next year. I suspect that it will change peoples expectations of torque and fuel economy in the SUV market forever, but that's jsut my personal opinion.
