An idling gas engine may be annoyingly loud, but that’s the price you pay for having WAY less torque available at a standstill.

Googling tells me that:
So the math here says electric gives you (0.97 * 77%) 0.75 MJ/kg output and gas gives you (46 * 30%) 13.8 MJ/kg output. Plus, as someone else said, spent gasoline no longer weighs you down.
I like the idea of electric, and I want to see it replace gas as soon as possible, but fair is fair.
Technically empty batteries weigh less than charged batteries.
Not that the difference is significant enough to tip the scale though.
How do you think about hydrogen cars? They have better fuel density, and hydrogen is renewable.
