No, it is still arbitrary to munge electric and fuel use together for a competition, but their individual contributions are not ambiguous, so it makes sense to track it at that level of detail. Just good form.

If your range extended trip is all hiway then there is a notable chance that you won't. But you are only dollars away from an optimal low loss transmission.

It doesn't need a more powerful engine, it need a less powerful one.
1. the conversion losses in series (mostly heat).
2. pusher is redundant. Depending on your range extending needs it doesn't have to push much at all and can be any size, though smaller is towards higher bsfc.

How did you turn a higher known peak efficiency across a wide portion of the rpm band into needing a larger engine?
