Whenever I hear people talk about acceleration in electric cars, they talk about the instant torque. I think I have an okay understanding of what torque is, but what does it mean for it to be “instant “?
In: Mathematics
It means an electric motor can apply its full rated “twisting force” (torque) from zero rpm.
An internal combustion engine has to build up some revs before its full “twisting force” becomes available. So if you have to build up, say, 3500 rpm, to the point where an engine is delivering its full torque, that takes time. An electric motor can deliver that full torque as soon as it starts turning.
