Mitsubishi Motors Corp. is likely to have sold over 2 million cars since 2002 using data collected by a method not compliant with Japanese regulations for gauging fuel economy, sources said Monday.
Mitsubishi Motors, tarnished by a scandal over its fuel economy data, is believed to have conducted driving tests on over 10 models without following Japanese regulations and submitted the data to the government.
The fuel economy of the models was calculated by using running test data, according to the sources. The running test method is used in the United States and can save testing time but is not approved in Japan.
