Nathan, you still have some digging to do. Do you think an engine supplying electricity to 4 hub motors is going to have a constant load and rpm? That negates the advantage of series hybrids you cite - steady operating state. As spw alludes to, series hybrids may allow peak engine efficiency, but a parallel or parallel/series hybrid make the best use of the energy, since it can both take advantage of efficient engine operating conditions AND the efficient mechanical transmission of engine power at steady speeds. The comparison to trains just shows your lack of understanding - trains can use this "series" drive without a battery because the engine is able to respond to power demands fast enough for the purposes of a locomotive - not so with a car without seriously compromising your series hybrid "peak efficiency" idea. And yeah, while we're at it, lets use 4 hub motors for the fun of it instead of just one. Series hybrids do have a place however.
It is also nuts that you believe biodiesel is carbon neutral. So all the tractors and trucks in the distribution run B100, they clear no land to grow it, and they don't use fertilizers derived from fossil fuels? Right.
