You've asked a very good question:

One possibility is the peak efficiency point is not at some given vehicle weight and power combination but actually is achieved at one end of the scale. It might have been the lightest hybrid, the Insight, achieved that spot.

Now there is another metric, the payload vs. efficiency, and that might move the scale up towards higher weight vehicles. But I don't think they really addressed that question (future paper???)
