With almost every brand having an Electric Car on the market or coming
soon, it leads me to think, are there some generic designs of motor, and

Suspension for many brands).
Setting up an efficient motor production line from scratch would need some
advanced thinking - surely they are all buying into existing manufacturing
engineering.

Any thoughts as to who the big players are?

Those are called "crate motors".

There are some for BEVs.

The big players don't use them.

GM put out an article a few months back,
where they showed pictures of their
"engineering fleet" of electric motors. And these
will be what eventually appears in their
vehicles. The things looked as ugly as a pile
of used GM transmissions.

VW has a few "common platforms" for its vehicles,
and the Volkwagon Microbus thing will use the same platform
as one of the existing cars. Just change the body on
top, retune suspension and so on. I hope they
don't forget to put a gasoline heater in the glove box.
Think how that will extend the battery range.
