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:

Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.

Next Mazda CX-9 spied for first time

After plenty of rumors, we finally have our first look at the second-generation Mazda CX-9. Development of the crossover look to be very far along based on these of production bodies hidden under form-fitting camouflage. The overall aesthetic, based on what we can see here, is very much in keeping with Mazda's handsome Kodo design language. The CX-9 you see here looks pretty much like a Mazda3 scaled up about 279.3 percent, with a five-pointed grille and expressive headlights prefacing a sculpted, swooshy body. In back, there's an aggressively raked rear window that won't do any favors for cargo capacity, but makes for a handsome silhouette. And if previous Mazdas are any indication, we'd expect the CX-9 to feature a very handsome, high-quality cabin, although it's impossible to see in these images. According to our spy photographers, the new CX-9 will abide by Mazda's Skyactiv philosophy, which should make for both an entertaining an efficient three-row crossover. A 2.5-liter, turbocharged four-cylinder will be the engine of choice, replacing the antiquated V6 of the current model, and will be available with an all-wheel-drive system. While this engine is slated for the CX-9, enthusiasts should take note that this first Skyactiv turbo will likely form the basis of future Mazdaspeed efforts. As previously reported, the CX-9 will make its debut this November at the 2015 Los Angeles Auto Show as a 2017 model. Should any info pop up before then, expect to see it here.
