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:

Toyota retires robots in favor of humans to improve automaking process

Mitsuru Kawai is overseeing a return to the old ways at Toyota factories throughout Japan. Having spent 50 years at the Japanese automaker, Kawai remembers when manual skills were prized at the company and "experienced masters used to be called gods, and they could make anything." Company CEO Akio Toyoda personally chose Kawai to develop programs to teach workers metalcraft such as how to forge a crankshaft from scratch, and 100 workstations that formerly housed machines have been set aside for human training.
The idea is that when employees personally understand the fabrication of components, they will understand how to make better machines. Said Kawai, "To be the master of the machine, you have to have the knowledge and the skills to teach the machine." Lessons learned by the newly skilled workers have led to shorter production lines - in one case, 96percent shorter - improved parts production and less scrap.
Taking time to give workers the knowledge to solve problems instead of merely having them "feed parts into a machine and call somebody for help when it breaks down," Kawai's initiative is akin to that of Toyota's Operations Management Consulting Division, where new managers are given a length of time to finish a project but not given any help - they have to learn on their own. It's not a step back from Toyota's quest to build more than ten million cars a year; it's an effort to make sure that this time they don't sacrifice quality while making the effort. Said Kawai, "We need to become more solid and get back to basics."

Scion rules out roadster, turbo versions of FR-S

Ever since Toyota and Subaru released the sports car alternatively known as the GT86, 86, BRZ and Scion FR-S a couple of years ago, rumors have circulated that even more exciting variants could be in store. But at least as far as Scion is concerned, those rumors are apparently nothing more than wishful thinking. Speaking with WardsAuto at the LA Auto Show last week, Scion chief Doug Murtha said that the prospect of an FR-S roadster has been taken off the table entirely. Apparently Scion lobbied parent company Toyota to produce just such a model, but after failing to find other markets interested enough in the model to put it into production, corporate HQ said no. "I think we were pretty aggressive on our (submitted plan), but we looked at what we would have conceivably lost on the product and said, 'We're not going to even push it further,'" Murtha said, going on to note, "Nobody was more disappointed than we were." Murtha further shot down the idea of a turbo version of the FR-S, dismissing it as a prospect the blogosphere (that's us) wanted to happen but "that's not something that's coming." Either variant might have helped Scion and Toyota boost sales of the model (which are predictably dropping after their first two years on the market), but the investment also might not have paid off their development, tooling and marketing costs. Of course, Murtha can only speak for Toyota, but we'd be surprised to see Subaru go it alone on either model, as costs would be that much more prohibitive without a partner. Bummer.
