Thus, if these numbers are correct, the H3 is about 1.4% more powerful than the H2 per weight carried. If you add the same equal weight, say 500 lbs, of people and cargo, to each vehicle, this does favor the H2, a little, but the ratio then becomes 1/21.23 for the H2 vs. 1/21.49 for the H3, which is only a 2.1% advantage in power/weight for the H2.

Is the reason the H3 is/seems less powerful because of the higher rpms required of the I5 or something else?

You said a mouthful but you left out the most important factor - Torque. While HP is how quickly you can get "work" done, Torque states how much you can do.
