Oh yeah! Electric motors can have max. torque at zero or
near-zero RPM, like steam motors, then you can rev the hell
out fo them.  Generally speaking, anything more than a simple
two-seed range selector indicates bad design, and even that
could be eliminated if you could spec everything.

I really don't understand the need to make an electric car
"feel like" a gasoline car right down to the gas pedal. What's
the point? It ought to drive like an electric, and you'd
learn to feel it like an electric. It will have it's pleasant
characteristics just like infernal combustion (for example:
TORQUE!)


My smart idea (meaning: I'll never build it) is stick the motor
anywhere convenient and drive a hydraulic pump that drives
hydraulic motors at all four corners (they're tiny)! And with
complex valving use the same wheel-motors to do braking and
drive the motor (or separate alternator) (NOTE) to recover the
energy. Super low un-sprung weight: the hub itself is motor
and brakes.

NOTE: so that you can do simultaneous accelleration and braking
as in autocrossing. Also, there's no easy way to stuff the few
megajoules of energy created in a 70MPH panic stop back into
the batteries that quickly; store it as HOT HOT HOT compressed
air (the heat is energy that creates higher pressure gas) the
container of which drives a smaller alternator to recover the
energy over a minute or hour or two. If you're in the habit of
making multiple 70MPH panic stops in a row, it just dumps the
excess heat.)
