I used to fix these hummers in the USMC and it was only till 1998 that the the Hummer A1 as we called it was upgraded from 1 1/4 ton to the Hummer A2 2 1/4 ton with the 6.5 liter diesel allen and 4 speed overdrive tranny. And what a difference it was compared to the old 6.2 liter and 3 speed tranny with no park or overdrive. The difference in power and performance was incredible and the fuel economy depending on the tires and how it was driven reached 25 miles per gallon. Not bad for such a heavy truck. Put that engine in something half its weight and sleek you have one economical vehicle. And another reason for having a diesel engine you cant kill it. If well taken cared of you can get 250,000 miles no sweat.
