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:

Deltawing takes out second ad targeting Nissan amidst design lawsuit

Don Panoz isn't a guy shy away from a fight. Since December, Panoz's Deltawing Technologies has been in a lawsuit with Nissan over alleged intellectual property violations with the design of the Zeod RC. The situation went public several weeks ago when Deltawing bought an ad in The Tennessean, a paper near Nissan's US headquarters, and the industry trade, Automotive News, aimed squarely at company CEO Carlos Ghosn.
Now, Deltawing is trying the tactic a second time with an even more scathing ad in The Tennessean on July 11 and in Automotive News on July 14 that calls the Zeod's design out directly. The bulletin puts the two racecars side by side and asks readers compare their similarities.
According to Deltawing spokesperson Gary Fong, the idea for these ads started after mediation between the company and Nissan broke down earlier this year. "We were trying to bring them to settle it amicably," he said to Autoblog. When that didn't happen, Deltawing wanted to fight the misconceptions in the public about the program and lawsuit. The strategy actually worked, too. "We've seen an opinion change," said Fong. He estimates that before the advertisements the attitude was "90 percent against Panoz," but there has been more support since them.

Semi-autonomous Nissan Leaf certified for road use in Japan [w/video]

In order to meet its goal of having an autonomous car in production by 2020, Nissan is going to have be able to test its technology in real-world driving conditions. For this, the automaker has just received a license plate to legally test its semi-autonomous driver assist systems in Japan, marking the first time such technologies have been tested on that country's roads. Not ironically, the license plate number is 2020.
Though not fully autonomous, this Leaf prototype will test various components of a self-driving car including exiting the highway, the ability to stay in its lane and change lanes when needed, stopping at red lights and overtaking stopped or slow traffic. Nissan is also in the process of building a proving ground in Oppama, Japan dedicated solely to autonomous cars, but the ability to test on public roads will obviously play a crucial role in the development of these cars. Scroll down for a short video and press release Nissan posted to mark the occasion.
