Glad we're already starting with the torque-at-wheels vs speed representation

See ~7:22 in this video:



If you take an EV car and a CVT ICE car with the same peak power,
they will have nearly identical torque-at-wheels vs speed graphs.

If you then take a typical 6-speed manual transmission instead of CVT,
the engine will operate below peak torque at most speeds,
meaning the torque-at-wheels will be lower than that of the CVT car.

Even though the EV will not have the "drama" of increasing torque
some ICE cars have when accelerating in one gear, it will in fact be faster
