Fuel economy at 80-mph went up 57%.
This paper was presented at SAE semi-annual meeting,June 4,1941.
By this time,Chrysler had a Cd 0.244 car which required no added length as was needed in 1934.
I'll digest the thing,update my drawings and do a complete thread ASAP.
Aerodynamics.It doesn't work! Wouldn't even consider it!

I don't those number make sense in the context of modern streamlined vehicles. .244 from an Airflow when the Insight 1 is .25 and the new E class MB is .24
Hucho (Yes I bought the book.) makes the comment in his history section that the historical numbers are somewhat suspect because of the improvements in measurement technology.
Not saying that the Airflow didn't achieve some good numbers, but I seriously doubt that it is as good or better than modern efforts
