TOKYO -- Japanese investigators raided Suzuki Motor Corp.'s headquarters today as they probe the automaker's use of improper fuel economy tests, an official said.
Investigators were looking for confirmation of Suzuki's claims that it had used data compiled from indoor tests performed on individual parts, rather than vehicle coasting tests, the transport ministry official said.
Suzuki's improper tests involved 14 branded models and 12 models sold under other brands.
Japan's No. 4 automaker by sales has said it lacked the resources after the 2008 global financial crisis to meet regulatory testing standards. It also cited increased pressure to develop models and engines in the late 2000s.
It was the second such raid by the transport ministry on a Japanese automaker after Mitsubishi Motors Corp. in April, as the government cracks down on manufacturers over the mileage testing scandal.
Mitsubishi's admission that it had misrepresented its fuel economy readings led to Nissan Motor Co.'s decision to take a majority stake in the smaller automaker and the resignation of its president last month.
