I'll hold off judgment on the split cycle until I see HP/TQ/fuel econ ratings versus a similar displacement engine in two identical vehicles. I still see it as problematic as it still relies very heavily on gasoline(and or diesel) for power.
Then I'll want to see how well it does on a race course. But that's just me.
