They said that the graph was made by holding the aero drag constant while reducing the weight. So aero drag would assume a higher proportion of the total energy use as weight was reduced. Presumably this could apply to a Prius that had been "lightened" by removing unneeded (for the competition) interior items, changing windows to lightweight materials, etc. But I'm not sure how applicable it would be to purpose-built car. Surely the aero drag could be reduced also and then the regen would take on a higher proportion of the total savings.
