Mitsubishi Motors Corp. said Wednesday its group net profit for the April-December period soared fivefold from a year earlier to a record ¥88.41 billion, driven by the yen's depreciation despite a decline in sales in Thailand.

Its operating profit grew 135.4 percent to ¥96.30 billion on sales of ¥1.52 trillion, up 18.4 percent.

The yen's fall versus the dollar and other major currencies positively impacted operating profit by ¥55 billion, the automaker said.
