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:

Some NY cabs could avoid hybrid ban

The Nissan NV200 is having a rough go of it as New York City's Taxi of Tomorrow. The Greater New York Taxi Association wants the van banned on the grounds that it isn't a hybrid, and has gone so far as to sue the city to keep the NV200 out of taxi fleets. According to The New York Times, the city has responded by proposing to allow taxi drivers to use certain hybrid vehicles. The Taxi and Limousine Commission's proposal would allow any vehicle with an interior volume of 138 cubic feet or more. Unfortunately, that excludes nearly every machine that isn't the size of the NV200.
Technically, Nissan is working on a hybrid version of the Taxi of Tomorrow, but it may be years before that model hits the streets, and the Greater New York Taxi Association isn't satisfied with the city's offer. In a statement, the Association said, "These rules look like they have been created to short-circuit the litigation. We do not consider this to be a serious proposal."

Mitsubishi admits to tampering with fuel economy data

Mitsubishi admitted this week to intentionally rigging fuel-economy testing in four of its models sold in Asia. The affected models are all so-called Kei class cars with sub-660cc engines manufactured at Mitsubishi's Mizushima plant in Okayama, Japan. About 157,000 of those cars are Mitsubishi eK wagons and eK Space models, and 468,000 are re-badged Nissan Dayz and Dayz Roox cars, which Mitsubishi produces for Nissan. The matter came to light after Nissan found inconsistencies in reported mileage data, which then led to Mitsubishi launching an internal investigation. The fraud was discovered to be related to falsified tire pressure data, which has an effect on mileage results – an important matter considering these kinds of vehicles are marketed by fuel economy. Mitsubishi said it has stopped manufacturing and marketing the affected vehicles. The news caused Mitsubishi's stock to plummet over 15 percent, slicing $1.2 billion off the company's value. When the eK models hit the market three years ago, they were decorated with a Good Design Award by the Japanese Ministry of Economy – a merit that is now surely tarnished. While Mitsubishi has been suffering in the US recently, with news of the Normal, Illinois plant closing, its small Mirage model has sold well.
