Mitsubishi admits to manipulating fuel economy figures

Discrepancy affects more than 600,000 cars sold in Japan.

Mitsubishi admitted on Wednesday that it had overstated the fuel economy ratings of its eK series of kei cars, prompting a stop-sale on the tiny commuter car in its home market of Japan.

Nissan, which sells rebadged variants of the eK, discovered the discrepancy and notified Mitsubishi. Mitsubishi has admitted that the discrepancy is on account of deliberate test manipulation, rather than any sort of error in the calculation.

"MMC conducted testing improperly to present better fuel consumption rates than the actual rates; and that the testing method was also different from the one required by Japanese law," the company said in a statement Wednesday morning.

"We express deep apologies to all of our customers and stakeholders for this issue."

So far, the affected Mitsubishi models include eK Wagon and eK Space. Nissan's rebadged lineup also appears to be affected, which would include the Nissan Dayz and Dayz Roox models (whether the Highway Star variant is affected is unclear at the time of publication).

Mitsubishi plans to evaluate other models sold both in Japan and abroad for any similar disparities.
