It has to be the connecting rod / crankshaft that are causing the greatest loss within the engine, or the long 3 strokes of coasting, or something basic, that is keeping ICE's from being 50-60-70-80-90% efficient, right? ...

you cannot compare electricity to gasoline like that.
That is what this 16 page thread Started by Ernie Rogers is about (which took me a while to get, having gone into it with electrical bias too):

And is also what is wrong with mpge.
The electricity has undergone the major heat losses at the powerplant, when they burned the coal or whatever to make the electricity. You are using a refined form of power. It would be like using compressed air to run an engine, and not counting the energy used to compress the air in the first place.
It isn't the crankshaft, it is thermodynamics.
