That's 54 ponies, and I won't even have to push them to 100% to do what I want. I'm not asking for half the speed. I'm asking for about 65%. So, I only need a little over half of the estimated power that I'd need at 70. Bu y that very, very rough estimation. 20HP, or 15KW should be enough. I'm packing a full 30% more just to let the gens run in a more comfortable range.
Does this goal assessment seem a little more rational?

Hi camosoul,
Your math is a little off. But I'm in complete agreement: if 45 is your top speed requirement, 20 hp is plenty.
I really like the idea of a serial hybrid pick-up. In my dream I have 120 vac available for all my tools, fridge, electronics, etc. And then I can drive it all home.
