The Company's activities continued uninterrupted through the 1970s eventually evolving as one of the largest producers of four wheel drive vehicles in Iran. Following the 1979 Islamic Revolution, the Company ownership was transferred to the State, and IDRO (Industrial Development and Renovation Organization of Iran) took control of the Company as the Government industrial arm, and as such, the Company underwent a change in the management (expropriation). Despite this transition, production continued unabated and by 1983 the Company achieved record production levels.
