Forever I never contemplated what the greatest single power drain on a ICE was.
It's the compression stroke. That one factor has to sap maybe more than half the power generated by the power stroke.
So the bigger the motor the more the loss at compression. Then of course there is the cumulative inertia and friction in all those parts. The power to get it going and to keep all that going has to be enormous.
At some point those 3000 HP ICE motors with blowers on 'em that take about 600 HP to drive seem to get past all that and really produce power way far in excess of their weight compared to conventional ICEs.
But the maintenance ohh the maintenance.
The E motor just turns on a set of bearings.
