AUDI: Cd 0.10 by 2002-2007
 

' 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.'

We're supposed to take this guy seriously?

'seriously"
 

Absolutely!
It's bio-mimicry, where manned flight came from, airships, blimps, aerostats, submarine external hulls, fuselage, wing tanks, belly tanks, canopies, blisters, fairings, radomes, torpedoes, suppositories, valves, acoustic stealth, fans, pumps, turbines, keels, control surfaces, helicopter rotor counterbalance fly-weights, air-brakes, etc..
When you figure out how a peregrine falcon has 1-1/2-pounds of aerodynamic drag at 257-mph, you get the gist.
' ... the aerodynamicist must refer to a large amount of detail resulting from earlier development work.' Wolf-Heinrich Hucho, Preface, 2nd-Edition, AERODYNAMICS OF ROAD VEHICLES, December, 1986.
The Aerodynamic Streamlining Template has the peregrine falcon as an antecedent.
Trailing-edge technology!;)

No beef with biomimicry.

Calling a penquin a fish is akin to California's logic

Didn’t Mercedes say the new eqxx was also shaped and sculpted by nature?

How far back do you want to go with Mercedes?

The 2005 Bionic?

1923 Benz Tropfenwagen (Rumpler patent, Porsche co-design)?

The design must be accepted by consumers.
The drivers still want beautiful cars, not economical ones.
