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:

Nissan IDx 'in the plan' for production, needs support from fans [w/poll]

If there's a trend in the auto industry we can firmly get behind, it's the small, light and affordable rear-drive coupe. The positive critical reception to the Scion FR-S and Subaru BRZ twins has encouraged other manufacturers to look at building their own rear drivers, and even a few to show actual concept cars based on the idea. The Chevrolet Code 130R from 2012 and more recently, the Nissan IDx twins that were first shown at the 2013 Tokyo Motor Show both come to mind, as does the brand-new Kia GT4 Stinger Concept.
Nissan trotted out the IDx Nismo and the IDx Freeflow for another showing in Detroit and we'll admit to being totally smitten with both cars. Again. The duo draw inspiration from the iconic Datsun 510, a lightweight, affordable rear-driver that remains a cult favorite decades after production ended.
Now, a report from our friends at AutoWeek reveals that we may, possibly, hopefully see a production IDx, provided fans make a strong enough case for it. "It's in the plan," Nissan product boss Andy Palmer told AW. According to the report, Palmer said the IDx is "into the first sage of the development process. The next stage is project validation and then looking at the business case. It's no one's intent to waste millions of the company's money, so obviously we have a good feeling about this one."

2014 Nissan Pathfinder Hybrid arrives with supercharged engine, 26 mpg combined

Nissan just launched the fully redesigned Pathfinder for the 2013 model year, and now, there's a fuel-sipping hybrid version making its debut here at the New York Auto Show. The 2014 Pathfinder Hybrid packs all of the same features found in the standard crossover, but offers slightly better fuel economy and an improved cruising range, to boot.
The new hybrid is powered by a 2.5-liter supercharged engine (we're assuming it's a four-cylinder, though Nissan hasn't specified) coupled with a lithium-ion battery and 15-kilowatt electric motor, capable of producing 250 horsepower and 243 pound-feet of torque - 10 less horsepower but three more pound-feet than the standard V6 Pathfinder. Nissan says the hybrid crossover will be rated at 25/27 miles per gallon (city/highway), with a 26-mpg combined rating. This means that on a full tank, the cruising range of the Pathfinder Hybrid is a cool 526 miles.
What's cool about the hybrid packaging is that Nissan has managed not to have it interfere with any of the interior functionality - the Pathfinder Hybrid still packs just as much cargo and passenger space as its naturally aspirated sibling. Official pricing has not been announced, but Nissan expects the hybrid to command an additional $3,000 over the standard model.
