In 1944 the Steyr 380 truck was designed in Austria, licensing Csepel lorries and engines.

During 1968–1975 the evolution of Comecon (Council for Mutual Economic Assistance) changed the way Csepel operated.

Labor-MIM in Esztergom and later the Polish Jelcz & Star performed the final assembly.

In 1968 the Csepel started a new generation of RÁBA lorries incorporating the MAN engine (licensed).
