The electric motor has maximum torque at zero rpm unlike an ICE.

Unlike an electric car, my car doesn't start from zero RPM. I get
maximum torque in the range 1,600 - 2,800 rpm and it will very quickly
be doing that if I am trying for maximum acceleration from rest.


Actually of course an electric motor does not necessarily have maximum
torque at zero RPM. Not if you want to keep it from melting.


I imagine that electric cars have a control unit which gradually applies
power over a short period of time, following a well-defined profile, even if
you suddenly floor the accelerator, so you don't spin the wheels and give
the occupants of the car a tremendous kick in the back. You could even allow
the driver to select from a number of different limiting accelerations,
depending on whether he wanted smooth, sedate acceleration or brisk sporty
acceleration (with the risk that takeup of power may be a bit more jerky if
you accidentally press the accelerator slightly further than you intended).

It must be good to feel smooth, fairly constant acceleration, without pauses
in acceleration while the transmission (auto or manual) changes gear.

The 0-60 time is neither here nor there in urban situations. As most
have a 30mph speed limit.


No but I'm guessing that *in general* a car with a faster 0-60 time will
also have faster times for accelerating from 0 to 10 or 20 mph.


Well you guess wrong.
