The István Röck Machine, Boiler Factory and Foundry was an early supporter of the nascent Hungarian auto industry
The Röck family first offered scieves and scythes at the beginning of the 19th century. The company slowly and steadily expanded and by the end of the century it became one of the best-known industrial companies in Hungary.
It is not known how István Röck jr. got in contact with János Csonka, the Hungarian engineer who designed motorised tricycles and then a van for the Hungarian post .
Between 1905 1912 the Röck company built several postal vans and coaches for the Hungarian post.

Röck gathered considerable experience with these vehicles. Their next project was to set up a proper assembly line for passenger cars, based on a licence from the German Lloyd company. As early as 1909 a Lloyd-based Röck participated in the 1909 Prinz Heinrich Tour and the last recorded car was delivered in 1913.

Altogether 5 passenger cars and 41 commercial vehicles were produced over a period of 8 years.
