While I agree that the S55 generates much more average power, this chart is misleading when comparing area under the curve. The S65 still produces power for an additional 900RPM after the S55 dies off. To be more appropriately compared, the RPM axis of each engines should be scaled so that the power bands overlap (8300RPM on the S65 to align with 7400RPM of the S55). The S55 would still show more that the S65, but to a lesser extent.

Even better would be to plot power vs road speed. You need gearing to do that, but it would better depict the difference between the two powertrains.
