Mitsubishi eK Wagon

Mitsubishi has admitted to tampering with fuel consumption rates in four of its Kei-car models manufactured in Japan. The cars affected are the 660-cc Mitsubishi eK Wagon and eK Space, and the Dayz and Dayz Roox models, which the automaker produces for Nissan.

In an official statement, Mitsubishi says it has rolled out 157,000 units of the eK Wagon and Space, and 468,000 units of the Dayz and Dayz Roox from its Mizushima plant in Okayama. The company divulges that the testing method used was different from the one required by Japanese law, resulting in inconsistencies in the fuel consumption rates.

The error was first identified by Nissan, who then requested Mitsubishi to investigate the matter. The automaker reveals that the improper conduct in the testing was related to altered tyre pressure, which leads to more favourable figures in terms of fuel efficiency.

Mitsubishi confirms it has put a halt to the production of the affected models, while Nissan has stopped selling the cars. Both automakers will set up an internal committee to investigate the misconduct, including models manufactured for foreign markets.
