Mitsubishi Motors admitted systematically manipulating fuel-economy testing data

Summary

Mitsubishi Motors Corporation states that an internal investigation found fuel-consumption test results submitted for Japanese vehicle certification had been rigged to make fuel efficiency appear better, including use of a testing method that differed from Japanese legal requirements and arbitrary selection of favorable data. The company says the improper method dated to 1991 and that investigations identified affected current and historical models; it stopped minicar production, corrected figures and compensated customers. This is a documented company admission rather than a claim that a particular criminal judgment was entered. Direct company source: https://www.mitsubishi-motors.com/en/company/history/company/
