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's new TNGA platform could boost Prius to 58 mpg

First, let's put the necessary context around the phrase, "Toyota New Global Architecture platform." The platform is important, but it is just one flowering bud sprouting from the real action, which is the production processes that will create it. It is crucial to understand that TNGA is fundamentally about a revolution in how Toyota designs and builds its cars - it even includes an overhaul of management and human resources - with one of the benefits being the new platform that the 2016 Prius will ride on. The Daily Kanban goes in depth about the changes, but integrated development for powertrain and platforms serves to reduces costs through more parts-sharing at the same time as it creates more cohesive platforms that are lighter, more compact, and have more efficient layouts. Regarding hybrids, Toyota says the new drive unit layout along with small components could raise hybrid efficiency "by more than 15 percent." That might enable the 2016 Prius to return 57.5-mpg combined - almost 59 in the city, 55 on the highway. Plus, the higher rigidity, lower center of gravity, and better suspension of the new platform will provide a better driving experience. All of these changes will be reflected in platforms for large and rear-wheel-drive vehicles, too. It is factory and build-process refinement that allows the development advances to be fully exploited. Toyota is making its lines more flexible, partly by having actual assembly lines that can easily be shortened, lengthened, or trucked somewhere else, and partly by introducing machines that can build parts for many different vehicles on the same line as needed, without using molds. The flexibility extends to capital investment, too, with much less money needed in order to switch to a new product build. Toyota says it is doing this to "improve core vehicle performance and product appeal," the overhaul making it simpler to produce new designs and features. Factory workers benefit from the flexibility as well; being able to build more types of cars means they aren't hamstrung by the sales fortunes of a small number of models.

CARB uses tricked-out RAV4 EV to measure air pollution in California

The old-school Toyota RAV4 EV you see above is the California Air Resources Board's version of a non-participant observer. The all-electric vehicle cruises around the state measuring airborne pollution. Since it's powered by batteries, there are no tailpipe emissions created as CARB tries to get a handle on how dirty the roadway air is. The problem, CARB says, is that it is difficult to measure air pollution levels, "during calm conditions at night and in the early morning." There are over 250 stationary air monitoring sites in California today, but the Board wanted a way to expand where and when it can test for things like ultrafine particles, carbon dioxide and nox. The original plan for the Mobile Monitoring Platform – as the RAV4 EV is officially called – was to "Investigate Spatial, Diurnal and Seasonal Pollution Gradients" on California's highways and ports. The RAV4 EV was originally expected to cost $280,000 (see pages 11-12 in this PDF from 2009), but a new report in the Modesto Bee says it had a total of $300,000 just in monitoring equipment. Michael Benjamin, CARB's chief of air monitoring, told the Bee that the MMP, "paints a thorough picture about what air quality is in any given community." More importantly, the stationary and mobile testing equipment can tell CARB when and where the air is getting cleaner. Which is the whole point, after all.
