why would we think that this type of machine/drive combo are as efficient as a suitable synchronous machine ?
(yes, I have read the previous post)
autogyro iirc posted some very impressive synchronous efficiency/performance plots some time ago
To answer that I would just post the previous papers, because they explain it all.

Are you 'saying you know who', or you talking about K factors and admittance?

What happens to an ICE, at anything other than closed throttle, when the load is removed? It's not a perfect world with constant tyre adhesion, and the ICE is not a constant power device at all rpm's/throttle openings. Accelerator pedal linked 'traction control' is illegal under current rules.
