It is not just Volkswagen trying to manipulate testing of its cars. This time it is a Japanese company, Mitsubishi.

The Japanese automaker received a visit Thursday from the country’s chief cabinet secretary. The government wants to investigate Mitsubishi’s fuel efficiency claims.

On Wednesday, Mitsubishi president Tetsuro Aikawa admitted that his employees used higher tire pressure during fuel economy tests for small car models.

The more air in a tire, the better it will perform on a fuel economy test. The test recorded 10 percent better fuel economy than consumers were seeing on the road.

The cheating affects over 600,000 cars produced for Mitsubishi and Nissan. The models are the eK and Dayz Roox passenger cars.

The Japanese government promised to deal with Mitsubishi in a “strict manner.”

Mitsubishi’s stock price dropped significantly on Wednesday and Thursday after the news of an investigation came out.
