Suzuki has admitted it found discrepancies in its fuel economy and emissions testing methods in Japan, but insists it did not manipulate data to make its vehicles appear more efficient.
On Wednesday, the automaker released a statement admitting that it had employed testing methods different to those required by Japanese regulations on some 16 models sold in that country.
“Acts of injustice, such as manipulation of fuel efficiency data, were not found,” Suzuki said.
“Some discrepancies were found in the automobile emission and fuel efficiency testing process between the regulation by MLIT [Japan’s Ministry of Land, Infrastructure, Transport and Tourism] and the actual method carried out by Suzuki,” the statement explained.
“We would like to express our deep apologies to all our customers and stakeholders on this issue.”
Although some 2.1 million vehicles are affected, Suzuki said that the issue does not include vehicles sold outside of Japan. It added that “all certified values remained within the range of measurement deviation”.
