Neither vehicle could get there using what NASA or Porsche used.
If 0.238 and 0.28 were the ultimate goal,then NASA was able to squeak by Carl Breer's 1934-1/2 DeSoto Airflow,and Porsche was able to match Edmund Rumpler's 1928 Tropenwagen.
Both a great success!

When you scale down the template, you scale down your success.

I have a new catch phrase.

Stock Porsche 911.......................................0.28 Cd
Porsche completely redesigns the 911 Carrera

(1) Standard DeSoto Airflow sedan----------- Cd 0.546
(6)............................Full experimental aero: Cd 0.238


More than one way to get there?
