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:

NHTSA investigating 200,000 Sentra, Versa models over brakes

The National Highway Traffic Safety Administration has opened a second investigation into Nissan in May. The first covered inaccurate fuel gauges in the 2007 Quest minivan. The latest affects the Sentra and Versa from the 2013 and 2014 model years and the 2014 Versa Note, because of complaints of long brake pedal travel. If NHTSA finds a problem, it could affect an estimated 200,000 vehicles.
At the moment, this is still only a preliminary evaluation "to asses the scope, frequency and safety-related consequences of the alleged defect," according to the report, but it could lead to the full recall. NHTSA is still trying to find whether or not there are accidents, injuries or fatalities related to the problem. At this time, much of the data in the document is still marked Confidential or TBD. Nissan told Reuters in a statement that the company is working with the agency on the investigation and supplying the regulator with further information.
According to NHTSA, its Office of Defects Investigation has received eight complaints about long pedal travel in these models. They allege that the brake pedal goes all the way to the floor when pressed in some cases and doesn't sufficiently slow the vehicle. Autoblog has contacted Nissan for its reaction to the investigation. We will update this story when we receive a reply. Until then, scroll down to read the current investigation report.

Dacia Duster to spawn inexpensive Nissan Terrano, will we get it?

When going to overseas auto shows, one can't help but spend an inordinate amount of time eyeballing forbidden automotive fruit. It's often of the seriously rare, criminally powerful and six- or seven-digit variety. But more often than one might think, the genuinely affordable overseas hero makes us swoon, too. So it is with the Dacia/Renault Duster, the cheap-as-chips, hard-wearing utility vehicle. We've often thought that its basic, rugged charms would play well in the US if saddled with a low enough price tag, but we've never seen much of a window for that to actually come true.
But now, Autocar India is reporting that Nissan will flex its alliance with Renault to spin off a Duster of its own, one that exhumes the Terrano nameplate, a moniker once used for overseas versions of the first- and second-generation Pathfinder. The new model will feature unique sheetmetal to give it a familial look, but the interior will be the same, and we expect the same goes for the powertrain, meaning there will be a range of gasoline and diesel four-cylinder engines with both manual and automatic gearboxes and front- or all-wheel drive.
So, does that mean we'll get a Nissan version of the Duster-based Terrano to call our own? Sadly, almost certainly not. Company spokesman Dan Bedore tells Autoblog flatly, "There are no plans to bring this model to the US." Bummer. Even if it isn't ultimately as capable as the larger, long-in-the-tooth Xterra (it's more on par with the now departed Canadian-market X-Trail), we think the Duster's archetypal SUV looks and low cost barrier would win it plenty of fans in our market. Our guess is that redesigning the model to meet US regulations (crash, emissions, lighting, etc.) would be prohibitively expensive, and the Dacia/Renault model is built in some pretty distant facilities - Brazil, India, Romania and Russia among them - making the business case harder still.
