At the end of the War, the scarcity of resources and the necessity for mobility, independence and liberty, caused a large number of manufacturers to build smaller vehicles in order to fulfil customer demand, employing mechanics from motor cycle manufacturers..

Germany was one of the countries where the sale of the micro cars was most widespread, makes such as BMW, who acquired the patent, to manufacture what was to become the Isetta, from the make ISO, (Italy) and NSU were pioneers in the nationís development of locomotion. Although the sales did not continue for many years, the country stabilized itself, and economic recuperation was not long in coming, which provoked an important technological advance in manufacturing processes; lower costs, more possibilities, new more spacious and better equipped motorcars. NSU maintained its position, with the manufacture of the Prinz series as a utilitarian vehicle.

Economic evolution in Spain progressed at a slower rate until the birth of the 2 hp, R4 Seat 600, that replaced the Biscuter, Isetta and PTV among others.

The Micro cars form part of the evolutionary and economic progress in post-war Europe, contributing to the freedom and enthusiasm of many citizens.
