that isn't what the video said. Not sure where you got that from. I do know it goes out of straight series mode when it wants to be 15% more efficient.

it absolutely is, at least around here. Separately listing the energy sources is the only sane way to make sense out of it. If you want to see the electric bias in mpge, look at the all electric wave II which basically was pegged at 190 mpge for the knockout efficiency hiway test. Given the fvt is largely an electric car, it is no suprise that it got good mpge marks. Not a function of series-ness.
The volt is the only apples to apples example out there that I know of. FVT to insight?!? That doesn't make any sense at all. You are saying to compare an xprize trike to a production car and say that this is the basis for saying how great series is? The only thing that changes in the volt is a couple clutches, otherwise it is the same vehicle, thus infinitely less variables than you are trying to introduce.

25% less rotating wheel mass and contact area has to be good for something.
