I have to agree with Huck on this one.

I think a cleaner, more efficient deisel would be a better answer.

I do think the idea of a better mpg HUMMER is a great idea, BUT, the H2 is a pig! THey would have to put this truck on a major diet and that would jack up the price quite a bit. I don't think it's a matter of just using Tahoe/ Sierra Hybrid parts. The weight and full time 4wd is also a huge factor.
