Mitsubishi Motors Corp. Wednesday added a ¥19.1 billion special loss to its fiscal 2015 earnings due to the recent fuel efficiency manipulation scandal.

The automaker is expected to provide compensation for gas expenses to owners who purchased the cars in question and will also return government-sponsored rebates for environmentally-friendly cars.

Mitsubishi reached the figure after conducting in-house tests on the four minicar models whose fuel efficiency was exaggerated, a company spokesman said.

The charge cuts the Tokyo-based automaker's net profit to ¥72.5 billion from ¥89 billion that it initially reported on April 27.

Mitsubishi manipulated data for the eK Wagon, eK Space, Dayz and Dayz Roox to make them appear up to 15 percent more fuel efficient.

The firm said Wednesday that it is still unable to come up with a fiscal 2016 forecast.
