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:

eBay Find of the Day: 1990 Mazda Miata with just 27 original miles

Some cars have low mileage, and others have close to no miles at all. This 1990 Mazda Miata, currently listed on eBay Motors and located in Kingman, Arizona, falls into the latter category with only 27 miles on the odometer, according to the seller. But we have to wonder: how did one of the best-driving, most influential sports cars of the past two decades sit without being driven for 24 years? Consider it the seller's loss on this one.
The seller says he bought the car with 20 miles on it, and explains 6.9 miles were added when the car was towed home on a car dolly. It was never registered. Furthermore, the seller says the car didn't come with a set of keys, so he had to have a set made. Though the paint is clean and shiny, the Miata didn't escape minor cosmetic damage over the years, with scratches on the hood, the trunk and the factory hardtop that is included with the car. The front, right fender has a small dent as well, which can be seen in a picture. The seller says the car was stored in a building with windows, so the paint is faded a bit in some places. It's missing its antenna and the battery, and the only non-original parts on the car are the windshield wipers. The clear-title car comes with all paperwork, according to the seller, but, besides the owners manual, he didn't specify what other documentation would be included.
With bidding currently at $10,300 and the reserve not met, this Miata definitely isn't the deal of the century, and we have to question where the value is in this one. The way we see it, it's hard to justify the money if it can't be driven as-is (come on, no battery?), has questionable history, isn't rare and sat in storage for its whole existence. The "weather cracked" tires are probably just the first rubber parts on the car that need to be replaced before it can be driven, but at least the spark plugs were removed and the cylinders were filled with Marvel Mystery Oil prior to storage, which helps to prevent rust and corrosion from forming in the engine.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
