I found out a bit more about the revolutionary Chrysler Air Flow when researching aerodynamics. Chrysler pulled it off the market and went retro.
Regardless of Chrysler’s success or failure, designers the world over saw the revolutionary benefits of the Airflow design. General Motors introduced a fastback coupe appearance on all of their nameplates from 1942 until 1950. Countries with more expensive fuel considered these practical efficiency designs more important than styling and they imitated the Airflow. Volvo got a smaller copy of the Airflow into production; Peugeot with their 202 and larger 402 models found major sales success, and imitating the Airflow would be a secret of the success of a brand-new venture in the auto business called Toyota.
