I frankly think that it is foolish to keep this on the shelf. engineering dollars have been spent, so bring it to market allready!
I feel that this would be a perfect tahoe/suburban engine, as folks love the big suvs for their safety and capability, but are not pleases with the mediocre fuel economy of a gas powered mill. a 4.5l duramax and a 6 speed hydra-matic would be a beautiful combination in a SUV.
onto the pickups, many people drive pickups. in the half-ton segment, these folks may be city dwellers that buy a truck for the safety factor, or the all season versatility, or the people that work these trucks on a farm, ranch, or construction site. One thing that they have in common is that nearly all folks that buy a truck buy it for a reason. similar to the SUV market, people love these vehicles and will continue to buy them for a long time, and would welcome a jump in fuel efficiency that would be provided by the 4.5L duramax.
since the last diesel suburban and diesel half ton in the GMT400 body style, people have been hoping and waiting for GM to return them to market. Lets get going GM!
