There are a lot of assertions/assumptions/conclusions there that I don't agree with Ner. Serial hybrids are pretty half-baked in themselves, they are the least efficient way to extend your hiway miles. An ICE can stay within %10 of peak efficiency over a wide rpm range. Especially if you add things like dynamic valve timing.

If you were to replace the chain on your bicycle with a generator on the crank and a motor on the wheel, this discussion would come to a screeching halt as you realized first hand how inefficient that serial setup is.

It doesn't really matter if you add batteries, in fact it makes it worse in some ways (battery charge and discharge losses). But this is exactly what chevy is doing with the volt, grr...
