(Newser) – The new Volkswagen: Mitsubishi? The car company announced Tuesday it has been cheating fuel tests in Japan for the past 25 years, an admission that caused shares to fall by 10% to a record low, reports CNNMoney. Mitsubishi's market value had already plunged last week with news that engineers from Nissan—Mitsubishi is a supplier to the fellow automaker—discovered that improper fuel-economy tests were used on four models: the eK Wagon, eK Space, Dayz, and Dayz Roox dating back to 2002, reports Reuters. Tuesday's revelation widens the scope of the problem. It isn't clear how many vehicles are affected, though no cars sold in the US are believed to be. Mitsubishi President Tetsuro Aikawa says he was unaware of the manipulation and the company is investigating who's responsible, reports Bloomberg.

"I'm truly sorry that customers were led to buy vehicles based on incorrect fuel-efficiency ratings," he said, per the New York Times. "All I can do is apologize." The company said it's been using an unapproved method to measure deceleration, one that results in a too-rosy mileage rating. An industry expert says the unapproved tests may have been used on more than the four stated models, noting Mitsubishi has a "history of covering up faults." In the 2000s, it was involved in "Japan's worst automotive recall scandal to date" after burying safety records and customer complaints, reports the Telegraph.
