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:

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

Next Nissan Rogue flaunts its new look

Remember last April, when Nissan told us it would be launching five new models over the course of 15 months? Well, we've seen the Altima, Pathfinder, Sentra and Versa Note, so that magical fifth model has to be the new Rogue, which our spy photographers recently caught testing. Despite looking like a hodge-podge of black duct tape and garbage bags, we can clearly see that the new Rogue takes a lot of its styling cues from the Hi-Cross concept that Nissan showed at the 2012 Geneva Motor Show. And that's fine - we found that CUV concept to be a decidedly handsome thing, and certainly more attractive than the weird little Rogue that currently roams the streets.
Details surrounding the next Rogue are still very unclear, though our spies suggest that it could be powered by a new 1.2-liter supercharged four-cylinder engine, good for something like 113 horsepower and 140 pound-feet of torque. We'll see about that, since those numbers represent a drastic drop in power versus the current Rogue - to the tune of 57 hp and 35 lb-ft. A diesel engine for other markets is expected to be on offer, and a plug-in hybrid version is also rumored to be in the works, though that won't show up at the vehicle's initial launch.
If Nissan sticks to its plan of showing these five new models in the course of 15 months, that means we should see the Rogue in July. Of course, since things don't always go as planned, it could be many more months before all that camouflage is taken away.
