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:

Takata airbag recall spreads to China with 42k Mazda sedans

The scope of the problem with the faulty airbag inflators from Takata continues to broaden and is now reaching China, as well. Mazda is recalling 42,732 Mazda6 units there, produced by its local joint venture partner China FAW Car Company, to replace the front passenger airbags. It comes as part of Mazda's recall of nearly 160,000 vehicles worldwide, including about 34,600 in the US, according to Reuters.
This is the same problem that caused seven automakers in the US to recall an estimated 2.1 million vehicles in late June. The airbag inflators can potentially explode instead of deploying the airbag, which hampers the bag's inflation. In some cases occupants are also hit by the metal shrapnel, which can cause further injuries. In the US, Mazda is repairing the 2003-2007 Mazda6 (pictured above), 2006-2007 Mazdaspeed6, 2004 MPV and 2004-2008 RX-8 originally sold in or currently registered in Florida, Puerto Rico, and Hawaii.
This is hardly the first instance of this issue. Since 2001, there have been 20 recalls tied to the exploding airbags supplied by Takata. The problem is possibly linked to the propellant in the inflators, but there's no conclusive evidence of that yet. Most of the automakers in the US limited the most recent recalls only to a few humid states because moisture potentially exacerbated the problem.

Mazda replaces owner's crashed 2016 Miata with brand new car

The first shipment of 2016 Mazda MX-5 Miatas are finally here. Imagine the jubilant sensation of being among the 1,000 people to pick up the limited Launch Edition, only to feel eviscerated when the new roadster crashes hardly a mile away from the dealer. While it must be an absolutely horrendous experience, Mazda North American Operations is making things right for one forlorn couple. In what was surely among the first recorded crashes of the 2016 Miata in the US, a husband and wife recently went to pick up their new Launch Edition, but they were rear-ended almost as soon as they left the dealer. According to Jalopnik, the hit also caused the roadster to slam into the car in front and might have bent the frame. To make a bad situation even worse, the wife also needed to be taken to the hospital to be checked out. Mazda is coming to the couple's aid with a generous gift. Knowing that it's utterly unfair for the new owners not to enjoy some top-down driving while the summer lasts, the company is actually sending the pair another Launch Edition to replace their crashed example. According to a Facebook post by the dealer (below), the car should be available sometime next month. Hopefully, the couple can enjoy thousands of miles of roadster driving with this one. After hearing about one of our customers getting rear-ended just minutes after picking up their new Miata, Mazda is sending out a replacement next month! #LongLiveTheRoadster Posted by Tom Bush Mazda on Wednesday, July 22, 2015 Related Video:
