Re the salt flats racing, here is an excellent example of what I am referring to when I mention "unstated assumptions". It may well be that Hucho et al are assuming "normal highway speeds" (or maybe even "normal around-town speeds") whereas the folks out on the salt flats are running at much higher speeds and may therefore be getting different results.

However, the racing guys will often do things that increase drag in order to get better results in other areas like handling and traction so they may be lowering the car for reasons other than drag--reasons that would have nothing to do with improving mileage figures.
