dumb question about H2 engines

[darebren]

forgive me.. but were there any H2 production models over the years that came in diesel power?? also, were all the H2's since launch, V8's, all same engine 6.2?L?

was wondering if any models would be better on gas, yet still give me the big H2 body and interior space, and looks!

i'm looking at buying a used H2, or an '07 loaded H3 with a bunch of aftermarket stuff.
