> It's certainly possible to keep a generator charging a battery tuned more tightly into its peak combustion efficiency zone That is _exactly_ what cars like the Chevy Volt did. A much smaller gas engine running at peak efficiency and sending the power to the electric motors was more efficient than burning the gasoline directly. Electric motors are very efficient, and the transmissions losses are much smaller. There's hardly any transmission to talk about, usually it's just some reduction gears.
