Duramax H2

[Hummertech]

I know first hand, that GM is not planning on installing the Duramax Diesel into an H2, ever. End of story. However, Hummer is looking at many other Diesel engines that are used in other GM vehicle, or joint GM ventures in vehicles sold in other countries, trying to find one that would fit, and be a good engine
for this application. GM is planning on having a diesel in the H2 someday, but don't hold your breath for the Duramax.
