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:

2015 Nissan GT-R Nismo priced from $149,990* [w/videos]

Remember when they called the Nissan GT-R a supercar-slayer? You can drop the "slayer" part, because the Japanese brute known as Godzilla has long since grown from an ankle-biter nipping at the heels of giants to a giant in its own right. And if that's the case with the "basic" GT-R, it's certainly the case with the new GT-R Nismo.
While the base price for the GT-R has breached the six-figure mark, the Nismo version has just been priced ten bucks shy of $150k. Factor in the $1,595 destination charge and you're looking at a $151,585 sticker price. That may seem like a lot for a Nissan, but bear in mind what you're getting for all that scrap: the GT-R Nismo's 3.8-liter twin-turbo V6 has been optimized to deliver 600 horsepower and 481 pound-feet of torque to all four wheels.
We've yet to see official performance stats, but considering that the base GT-R hits 60 in 2.6 seconds with 55 hp and 18 lb-ft less muscle, the Nismo version ought to teach a lesson or two to exotic supercars costing twice or even ten times as much. Just check it out in the videos and press release below.

Updated Nissan Micra gets fresh look, more tech and 'New' name

A few months ago, Nissan gave the Micra (which is not for US consumption) a substantial styling update that included new front and rear fascias, and stuffed more technology into the interior, such as USB ports and auxiliary inputs for audio and a new media touchscreen. Though it's still based on the same fourth-generation architecture, Nissan now calls it the New Micra.
Overall the New Micra - also known as March in some markets - looks similar to but more taut than the vehicle that launched in late 2010, thanks to more angular headlights, a new bumper, a sculpted hood and a revised grille with the Nissan logo sitting inside a chrome V, which establishes a stronger link to Nissan's "corporate look." The rear end receives less-drastic changes, such as a new bumper, LED taillamps and a new infill panel at the bottom of the tailgate.
