You might go to SAE International's website and do a search there. They typically have an abstract for every paper, free to peruse, that often provides enough information such that there's no need to purchase the paper.
BMW and GM have both offered serial-hybrids, and they might have published answers to your questions.
The 'serial' Gen-II VOLT gets 37-mpg, driving coast-to-coast.
The 'parallel' Prius does the same @ 55-mpg.
Exploring the specific differences between the two vehicles might 'flush out' the explanation.
