Well, it is how trains have operated for a long while. An IC engine is most efficient when it is running at a steady speed with a steady load. So this takes the best from both worlds. You run the IC engine at its most efficient. Plus, you get the efficiencies of an electric drive train with a simpler transmission, if you have one at all, and regenerative braking. In a locomotive it seems to make more sence because of the scale. In millions of mass produced passenger cars it seems like excess baggage to me. Like an after-thought... "hey we need more range, let's slap on a little gas engine to charge the battery". JMHO. I think eventually the battery (and other) technology will make that unnecessary.
