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:

Suzuki and Daihatsu join Toyota electric vehicle venture

TOKYO — Suzuki Motor Corp and Daihatsu are joining a commercial electric vehicle coalition led by Toyota Motor Corp, the carmakers announced on Wednesday, helping the Japanese alliance expand its focus from trucks to smaller cars. The two automakers will each acquire a 10% stake in the joint venture, on par with Isuzu Motors and Hino Motors, while Toyota will hold a 60% stake, they said. "With Suzuki and Daihatsu joining the project and working together, we'll be able to expand our circle of cooperation to not only cover commercial vehicles but also mini vehicles," said Toyota President Akio Toyoda. "With this expansion, I believe that we'll be able to take one step closer to a better mobility society," Toyoda said. The move comes as Japanese automakers face growing competition from tech giants and other rivals making electric and driverless cars. Toyota, Isuzu and Hino launched the Commercial Japan Partnership Technologies Corporation in April to bolster their competitive edge in connected, commercial vehicles. Daihatsu's president Soichiro Okudaira said joining the pact and introducing connected, mini-commercial vehicles would allow data sharing, a major benefit for companies to provide better services to customers and improve logistics efficiency.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
