Development of car production industry in Yugoslavia has three ecological phases. The first one is to satisfy ECE Rules by optimization of engine and vehicle equipment. The second phase is to enter the American market with help of professional foreign development institutions. The third phase is now in focus; to adjust to new European regulations.For the development tasks it is typical to lean on foreign licenses. The real development jobs were occasionally given to faculties, while the research units in factories were overburdened by operative tasks from production. Research jobs were always at mother companies, only some small segment of them was, for the short period, at some faculty or larger institute.
