Reply to comment by max_p0wer in ELI5: Why are electric car engines/motors able to accelerate so much faster (0-60 mph) than internal combustion engines? by jacobhottberry

Not exactly. In a rotating engine, power is engine torque multiplied by rotations per minute. Electric motors don’t produce peak power at all engine speeds, because in order to do that, they’d have to produce peak torque at 1 rpm and then have the amount of torque produced gradually decrease as the engine speeds up.

What electric motors do is produce consistent torque at all engine speeds. They still have a power curve, it just looks a bit different than an ICE.

With an ICE, you only get peak torque at a certain engine speed, and you actually get less torque when the engine is going too fast.

Do a google search for Tesla dyno graphs. You’ll see the power is virtually flat while the torque decreases steadily. It’s constant power output, not constant torque.

I think the person you're replying to is thinking of DC motors
