OK check this out.
Electric motors make maximum torque at zero rpm, and zero torque at their maxium speed. Thats what Marc Berte, prsident of the impressive-sounding Horizon Defence & Aerospace Solutions, said?... I dont get it.
Oh yea check this one out too.
Shifting a manual transmission takes, at best, a quarter of a second per shift. In a quarter-mile run, this easily adds 0.7 to 1 second to your et. This is, of course, blatantly, obviously, false. In a 0-100 test, it would be true, since time not spent accelerating is time spent not getting any closer to 100 mph, but even as you coast though a cumulative 1-second of shifting, the car is still rolling toward the end of the quarter mile, so quicker shift times actually have minimal effect on you e.t.
What do you guys think?...

Addressing the first part of your post... It's true. Electric motors DO produce their maximum torque at zero RPM. Torque in an electic motor is produced by magnetic forces. The magnetic force is proportional to the current flow. At zero RPM, there is no back-EMF generated by the motor, and current flow is at it's maximum. As RPM is increased, the motor generates a back-voltage (back-EMF) which reduces the current flow and therefore reduces the torque. Of course, this is all not considering resistive and thermal losses, but holds true as a general statement.
