The gas isn't doing the rest though, it's charging the batteries as you're driving along. That's why the all electric range has to come down vs the regular one because space that would be battery becomes a gas motor and gas tank.
Picture an electric golf cart with a gas generator on the back. No axles, no transmission, the motor just charges the batteries when they get low.
