Once upon a time I designed bodywork. According to the marketing dept. and the press, EVERY new body was "more aerodynamic" than the last one- whether it was or not. None of the stuff we did was ever tested, but that didn't matter.
What we have to realize is, the press is full of ****. Another thing they did was rotate among manufacturers for the "______ of the Year" title, which was meaningless because the best piece of equipment wasn't going to win if it wasn't that manufacturer's "turn".
They are all about the hype and advertising sales.
