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:

Renault wants to merge with Nissan, then go after Fiat Chrysler

The late Sergio Marchionne used to say consolidation would be the only way to compete against the biggest global carmakers. The company looks certain to fulfill that goal, but perhaps not in the way he intended. The Financial Times reports that Renault wants to begin merger talks with Nissan in the next 12 months. Assuming a merger gets completed, the plan is for the combined company to then pursue another merger, with Fiat Chrysler a prime target. Renault, Nissan, and Mitsubishi have been busy since cutting ties with ex-alliance boss Carlos Ghosn. They formed a new alliance board with Renault chairman Jean-Dominique Senard at the helm, Renault has shrunk the size of its board while Nissan added more outside directors, and the two agreed to a new governance structure to ease operational decision making. All three automakers have walked away from Ghosn-era goals to sell 14 million cars and find 10 billion euros in savings by 2022. New strategic plans for all three car companies are in the works. With stability in sight, it's said Senard wants to succeed where Ghosn failed — a full-fledged merger between Renault and Nissan with talks to begin "as soon as possible." Ghosn's pursuit of a merger last year in attempt to make the 20-year-old alliance "irreversible" is part of what led to his downfall, with Nissan executives including CEO Hiroto Saikawa against the push. The new effort is presented as larger scale being the only way for the alliance to take on companies like Volkswagen and Toyota. But the Nissan-Renault-Mitsubishi trio sold 10.76 million cars around the world last year, second to Volkswagen with 10.83 million sales, ahead of Toyota with 10.39 million. If Nissan hadn't suffered a 2.8 percent dip in sales, the alliance would have taken the top spot. If a little scale is good that means more is better, right? Pulling Fiat Chrysler into the alliance would add around 5 million annual sales, and would be another move in Ghosn's footsteps. The former honcho is said to have "held talks with FCA" about some kind of union within the past three years. The French government, which has a 15 percent stake in Renault and double voting rights, shut down the initiative. It's not clear if FCA will be an independent company by the time a potential Nissan-Renault merger closed, though.

Nissan EV design is diverging in three directions

As the movie awards season kicks into high gear, Nissan design chief Shiro Nakamura appears to be implying that his company's electric-vehicle design prospects are about to go from Philomena into The Wolf of Wall Street territory. Nakamura, speaking with Motor Authority at the Detroit Auto Show last week, allowed that the design of the five-seat Nissan Leaf is fairly conservative and will remain so given that the model continues to be the most practically-minded EV from the company. In the near future, though, Nissan is planning to head in different directions. Specifically, an all-electric sports car and a two-seat commuter vehicle that could come with in-wheel electric motors that will allow the designs to get more radical. How radical? Well, we've heard Nissan may bring the BladeGlider concept (pictured) it unveiled at the Tokyo Motor Show late last year to production. It has a narrow front and wider rear and a 1+2 seating arrangement. Beyond that, Nissan has the two-seat Esflow concept vehicle it showed off in 2011 that could provide some hints, since it's expected that some of the design components from that car will be worked into the upcoming production models.
