I came across this diagram in a print advertorial for Toyota hybrid cars (scanned it, could not find it online). Click on the image for a larger picture.
The diagram supports all the points in the text. Still:
  • The image looks a bit retro
  • You actually need to study it a bit to understand it
  • Race bikers can go fast, however they are by far not as powerful as a modern hybrid car...
  • The text below the image does not flow very well
In short, the image is probably good enough for an internal management presentation, but does not meet the bar for external advertising. It is hard to find that perfect image or illustration...
