Mitsubishi Motors Corp. said Monday its first-half net loss widened to a record 146.2 billion yen.

The scandal-hit automaker, which posted a loss of 80.2 billion yen a year earlier, said it has also downgraded its full-year earnings forecast.

The grim outcome for the April-September period was mainly attributed to one-time losses, including 12.3 billion yen spent on restructuring plants in Japan and Australia and 19.9 billion yen in costs to conduct free inspection programs for Mitsubishi vehicle owners in the wake of a series of defect coverup scandals that broke in March.
