I'm not just talking about the hybrid drivetrain itself. Rather, I'm talking about all the stuff in them.

For example, power accessories like power windows eat into the battery life. If everything was manual, manual steering, windows, locks, mirros, etc. and NO AC or radio installed at all, and a manual transmission, then this would be the ultimate hybrid. It would also make the car lighter as well as reduce demand on the batery.

It would come as a 2- or 4-door hatchback or convertible (with a manual top and glass window, but only because plastic windows get yellow over time). It would come standard with ABS, tachometer, manual steering, gas-mileage indicator, and that's it. Options include side airbags, manual-sliding glass sunroof, air conditioning, a radio, rear defroster, and a rear wiper for the hatchbacks. That's it.
