' Within the next fifteen, twenty years, I think, 0.10 could be reached, because this Cd value is the same as that of a penguin, a fish/bird that doesn't look very streamlined. In terms of a car, it's a station wagon version. And if nature could build a station wagon at 0.10, then I think, with out development and research, it should be our target to be as good as nature was by itself.'
Dr. Ferdinand Piech, Vice-Chairman, Board of Management, Director of Research and Development, Audi Division, Volkswagen Group, in an interview with Bill Sharfman, page-81, AUTOMOBILE Magazine, November, 1987.

' (T)he drag of the ( Cd 0.09 ) basic body is achievable. To what extent this can be approached in the development of a production vehicle is therefore more a question of the balance of the requirements of the specification, than of technical feasibility.' Wolf-Heinrich Hucho, December, 1986, Preface, 2nd-Edition, 'AERODYNAMICS OF ROAD VEHICLES.'
