Japanese carmaker Mitsubishi is currently in a world of troubles. The brand has admitted to manipulating fuel efficiency test data related to as much as 625,000 cars in Japan. These vehicles include four different models – two of which Mitsubishi supplies to Nissan.
It all started when Nissan tested the cars supplied by Mitsubishi. To their surprise, the brand came across differences between Mitsubishi's published fuel efficiency data and their own results. According to a few Japanese reports, Mitsubishi rigged the tests by using a testing method that was different from the one required by the Japanese law.
In order to come up with better test results, Mitsubishi apparently varied the load placed above the vehicles' wheels. The brand also manipulated air and rolling resistance of the tyres. The affected cars include the eK Wagon and the eK Space sold as Mitsubishis, besides the Dayz and Dayz Roox that are made by Mitsubishi but supplied to Nissan for sale.
With this, Mitsubishi has joined a long line of carmakers who have admitted to rigging fuel efficiency and emission tests. While Hyundai and Ford are already in radar for misleading fuel economy figures of certain models, Volkswagen is now preparing to compensate for its mega emission scandal by setting aside around £4billion to pay towards the affected cars.
