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:

Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way. The politician in question is State Assemblyman Tim Eustace (D-Bergen), who was purposefully hit by a blast of dark smoke recently while driving his Leaf on the New Jersey Turnpike, according to NJ.com. This personal experience of what he called "just youthful ignorance" is encouraging him to submit a bill (A3583), which, "Prohibits retrofitting diesel-powered vehicles to increase particulate emissions for the purpose of 'coal rolling'; prohibits the practice of 'coal rolling.'" If you're caught violating the law, you would be hit with a fine from the state Department of Environmental Protection. Of course, the Feds say it is already illegal to modify an exhaust system in a way that allows coal rolling. Rolling coal has become a bit of a meme recently, with videos of laughing truck drivers spewing their modified exhaust pipes at green cars, pedestrians and bikers around the country. Eustace told NJ.com that, "People had been telling this has been going on, but I hadn't seen it. I was surprised to experience it myself." Perhaps a coal roller in New Jersey will be surprised, too, when the first big fine hits. News Source: NJ.comImage Credit: YouTube Green Nissan Green Culture Diesel Vehicles rolling coal

The art of racing the Nissan GT-R

There's no question that the Nissan GT-R is one of the very fastest cars that money can buy, and that its sophisticated all-wheel-drive system and active suspension give its drivers an absurd level of control at speed. In fact, the GT-R's technical brilliance and video-game quickness often spur armchair critics to make absurd claims that kind of amount to: "The car basically drives itself."
Having a bit of fun with those particularly salty members of the peanut gallery, YouTube producers at That Racing Channel have put together an instructional video about the finer points of GT-R driving and street racing. Scroll down below to get an idea about just how difficult Godzilla can be to keep hold of at the limit.
