Rumpler Tropgenwagon
This is the Rumpler Tropfenwagen (German for "drop car"), often considered the first aerodynamically designed production car.
Designed by Austrian engineer Edmund Rumpler and introduced at the 1921 Berlin Auto Show, its "teardrop" shape was revolutionary for the time, achieving an incredibly low drag coefficient.
Despite its advanced engineering and focus on fuel efficiency, it was not a commercial success, with only about 100 units produced.
It is now highly regarded as a milestone in automotive design history.
