Shares in Mitsubishi Motors Corp closed down 13.55 per cent in Tokyo following revelations this week that the company had manipulated fuel consumption test results.
Trading was halted Thursday in the company's shares in the wake of the scandal.
The Japanese carmaker's bosses admitted Wednesday that it had manipulated test results to present better fuel consumption rates for its smaller cars.
The company’s shares had already fallen over 15 per cent on Wednesday.
The scandal involves a total of 625,000 vehicles of four models, including cars sold by another Japanese car giant, Nissan.
