"Mitsubishi: We've Been Cheating On Fuel Tests For 25 Years"

"The situation at Mitsubishi Motors just went from bad to much, much worse.

The Japanese automaker admitted Tuesday that it had falsified fuel efficiency tests for the past quarter century, the latest revelation in a scandal that has rocked the company.

Investors responded by pushing Mitsubishi shares down by 10%. The fuel test scandal has now erased half of the company's market value, and its shares are sitting at a record low.

The automaker said last week that it had used improper fuel economy tests on hundreds of thousands of vehicles, including some sold to Nissan (NSANF). "
