Hucho claims in his text that should a person streamline their car,that the road load can shift so far,as to knock the engine out of it's island of highest BSFC.The car will also overspeed,and if the gearing is not changed such that the engine "see's" the same load as before the streamlining,then MPG potential from the drag reduction can suffer up to 60%.
