After WWII the Soviets prohibited the East-European countries to produce passenger cars.
In 1953 Hungary started a car building contest. This project focused on an intermediary type: the closed, three/four wheel motorbike for two adults and two children. This was the definition of the microcar. This is the project made by Imre Vogl.
In 1956, the year of the Hungarian revolution, the project was stopped. There was no winner.
