The “Rumpler drop car” was named after its raindrop shape. Edmund Rumpler, born in Vienna, was known as an aircraft designer introduced the Tropfenwagen at the 1921 Berlin car show. It was to be the first streamlined production car, before the Chrysler Airflowand Tatra T77. To enable the car’s aerodynamic shape, the Tropfenwagen also featured the world’s first (single plane) curved windows in a production car.

Although the car was very advanced for its time, it sold poorly – about 100 cars were built. Most were sold as taxis, where easy boarding and the high ceiling were advantages. The last cars were built in 1925. Only two examples are known to survive, one in the MVG public transportation museum in Munich, and one in the German Museum of Technology in Berlin.
