A Simpler Explanation Of The Measurement Of ONE HORSE POWER
One horsepower equals 550 foot pounds (pound feet) per second. In high school, in physics class, I generated 1 horsepower by running up a flight of stairs. :) Housted

I agree that there are reasons to appreciate the capabilities of an electric motor. The only point i was making is that stating an electric motor has the ability to generate 80% of its peak power over a 7000 rpm operating range doesn't mean much when that operating range is from 6000 to 13000 rpm.
Sorry I disagree the ability for the motor to run 0-18000 rpm while generating peak power over the middle of its range is a big reason why it doesn't need a multi speed transmission, along with 0 rpm max torque.
I believe Teslas a geared to reach max power between 40 and 70 mph. THe semi is interesting it looks like they are doing 23:1 on one axle and 19:1 on the other allowing an electronic blending of the ratio. Either way more than double the torque multiplication of the model 3 max power will come in much lower probably 20mph.
