Isn't it break even point, considering >60% of the gasoline energy is dissipated as heat, and <40% to make the wheels spin?

No, the number for gasoline is missing one zero; with the correct number, gasoline is still 6-8 times more energy dense per kg.

Thanks. I should have fact-checked the number before doing the math :)
