Mitsubishi faces fresh allegations of fuel economy test rigging, with the Japanese transport ministry suggesting the manufacturer has continued to manipulate results since it uncovered evidence it wasn't following correct test procedures earlier this year.
The Japanese car maker admitted that it had been manipulating its mileage and economy figures, but, according to reports in the Wall Street Journal, subsequent economy tests in May were also undertaken incorrectly.
Japan’s transport ministry reportedly accused the car maker last Thursday of continuing to test the fuel economy of its vehicles in the wrong way, despite it admitting its faults back in April.
Mitsubishi admitted to the manipulation of test data on four of its popular minicar models sold in Japan, resulting in 620,000 vehicles being certified as more fuel efficient than they actually were. Immediately following this revelation, Japan’s transport ministry advised Mitsubishi on the correct way in which it should be testing its cars, but the firm allegedly continued to doctor the figures one month on.
