Hmmm they might be running low voltage/high amperage AC. With
contemporary frequency controls, AC might be the way to control speed
and power. Does anyone know whether DC still provides the most
starting/low speed torque? Or have the variable frequency AC
controllers improved AC motors enou

The inverted rotor/stator design is such an obvious and elegant
solution to an electric drive for vehicles that one does wonder
why it hadn't been thought of before.
It has been thought of before. To my personal knowledge, it was
thought of at least 40 years ago.
There are several re
But there is actually no new tech involved, just some good brainwork.

difficult it is to "think out

It makes so much sense, too, ya gotta wonder why it hasn't been done
before. Is the necessary technology state of the art?
I don't understand your question.
Sorry.

Yeah that's very interesting but not new, It's basicaly a bus version of
an hybrid car like the Prius sold by Toyota

definitely my next car) the extra plus of that bus is the
