Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

Nissan explains its preparation work with the GTR LM Nismo

There are eight races in the World Endurance Championship schedule, the third one is the 24 Hours of Le Mans. The Nissan GTR LM Nismo has been designed specifically to compete in that race, and has missed the first two races of the season in order to carry out more testing for that third one, the season objective. Plenty of folks would tell you that racing is the best form of testing, but the Nissan project is doing things so differently that we wouldn't be surprised if they said they were testing on Kilamanjaro because that's just what made more sense. In the video, Ben Bowlby - formerly of DeltaWing - and other team reps talk about how the car was designed, how the choices were made, and failing the first rollover-hoop crash test. If they can keep it running, this year's Le Mans will be even more entertaining than usual.

Automakers Renault, Nissan will become equals, with equal stakes in each other

TOKYO — Nissan and Renault have agreed to equalize the stakes they hold in each other, both sides said Monday, ironing out a source of conflict in the Japan-French auto alliance. Up to now, Renault Group has held a 43.4% stake in Nissan Motor Co., potentially giving it a larger say in how the Japanese automaker is run. It will transfer shares equivalent to a 28.4% stake to a French trust so each side will hold the same 15% stake in the other, according to the companies. The disparity between the holdings was a cause of friction, especially after Nissan became far more profitable than Renault. The agreement on the change is still being finalized and needs board approval from both companies. The companies said the shares in the French trust can eventually be sold but did not say to whom or how. They said the sale will be carried out in a “coordinated and orderly process” if a deal makes commercial sense to Renault Group, and that there is no time deadline. Until then, the voting rights would be “neutralized” for most managerial decisions, but the economic rights, such as dividends, will continue to go to Renault, the companies said. The top shareholder in Renault is the French government. Japanese Prime Minister Fumio Kishida met with French President Emmanuel Macron earlier this month. The alliance has had its ups and downs since it began in 1999, when Renault sent one of its executives, Carlos Ghosn, to then-struggling Nissan to lead a turnaround. Ghosn first served as Nissan's chief executive and later its chairman before he was arrested in late 2018 on various financial misconduct charges. The alliance, which also includes smaller Japanese automaker Mitsubishi Motor Corp. and remains one of the world's top auto groups, has been eager to put the Ghosn scandal behind it. Allegations against Ghosn include underreporting income, using investment funds for personal gain and illicit use of company expenses, including overseas homes and a yacht. Ghosn said he is innocent of all charges. He jumped bail in late 2019 and is now in Lebanon, which has no extradition treaty with Japan. The equalization of the crossholdings has been speculated about for some time. The companies called the move “an important milestone.” “The ambition is to strengthen the ties of the alliance and maximize value creation for all stakeholders,” said Nissan, based in the port city of Yokohama.
