Mitsubishi Motors shares nosedived again today as panic selling wiped about USD 2.5 billion off the automaker's market value in response to its shock admission that it cheated on fuel-efficiency tests.
The embarrassing revelation is the latest in a string of recent scandals to hit Japanese firms, while German giant Volkswagen struggles to restore its badly dented reputation after a massive emissions scandal.
Japanese transport ministry officials raided a company research and development centre Thursday following the admission, as the government slammed the maker of Outlander sport utility vehicles and Lancer cars.
The embattled stock has freefalled, plunging to 583 yen (USD 5.31) in Tokyo, down 20 percent, after diving 15 per cent yesterday when news of the fuel-cheating first broke.
The scandal has also raised questions about Mitsubishi's future as it faces the prospect of huge lawsuits and fines.
"This has critically damaged consumers' trust and it won't be tolerated," top government spokesman Yoshihide Suga said today. "It's an extremely serious issue."
Mitsubishi admitted yesterday that unnamed employees rigged tests to make some of its cars seem more fuel-efficient than they were in reality.
The company said it would halt production and sales of the affected vehicle models - mini-cars sold in Japan including some made for rival Nissan - and warned that the number of cars involved in the scandal would likely rise.
Mitsubishi's top executive conceded Wednesday that the crisis would take a bite out of its bottom line, as the firm widens an internal probe to cars sold overseas.
"This is not a simple problem and we need time" to assess the impact, president Tetsuro Aikawa told a news briefing.
"But I'm sure there will be an impact. The damage will be big."
The collapse of Mitsubishi's stock yesterday was its biggest one-day plunge since 2004.
At that time, Mitsubishi was struggling to launch a turnaround as it teetered on the edge of bankruptcy, hit by a lack of cash and a series of huge recalls linked to deadly defects.
Bailouts by the Mitsubishi group companies saved the automaker, which had covered up defects linked to flawed axles that could lead to wheels coming off the car.
