Simple question. I've been reading qualitatively about the torque and power curve of electric engines versus internal combustion engines. I'm led to understand that electric engines get much higher torques even at lower speed. One argument for why electric cars are inherently more efficient than IC cars, in particular for urban travel. I'm wondering why, is it due to the fact that the high energy content of fossil fuels can be surpassed by that of x amount of current and voltage? Thanks in advance.
