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:

Next-gen Nissan Leaf will look more mainstream, have more range

The next-generation Nissan Leaf battery-electric vehicle will look better and go farther on a single charge, company executives tell Automotive News. How much better and how much farther remains to be seen, as does the timing on when the new version will be available to the public. Nissan executive Andy Palmer, speaking recently at the Beijing Motor Show, implied that an electric vehicle would need to have a 185-mile single-charge range to be competitive with hydrogen fuel-cell vehicles, once those arrive in larger numbers. While Nissan boosted its single-charge range by about 15 percent for the 2014 model-year Leaf, the automaker would need to double it to reach that competitive threshold. This seems unlikely for the next-gen model, but we can start making our guesses as to how many more miles Nissan will put into the pack. Regardless, the next-generation Leaf, which may come out around 2017, will at least look a bit more mainstream while it reaches for more range, Automotive News says, citing Nissan global design chief Mamoru Aoki. Indeed, the car, which will keep its hatchback layout, will likely look less angular, said Aoki, who complimented Tesla for the way it styled its Model S luxury electric sedan. Nissan's Infiniti arm could also debut its delayed luxury electric vehicle in 2017, complete with the improved battery pack. Angular looks and all, Nissan continues to increase sales in the US. Leaf sales through April were up 33 percent from 2013, to 7,272 units after more than doubling sales last year to 22,610 vehicles.
