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:

Waymo partners with Nissan, Renault on robotaxis outside U.S.

SAN FRANCISCO — Self-driving car pioneer Waymo is teaming up with automakers Renault and Nissan to make its first journey outside the U.S. with a ride-hailing service that will dispatch a fleet of robotaxis in France and Japan. The partnership announced late Wednesday underscores Waymo's ambition to deploy its driverless technology throughout the world in an attempt to revolutionize the way people get around. The Mountain View, California, company can afford to try because it's backed by one of the world's richest companies, Google, which secretly began working on driverless technology a decade ago before spinning off that project into what is now known as Waymo. After launching its ride-hailing service in France and Japan, Waymo intends to explore other European and Asian markets with Renault and Nissan. "This is an ideal opportunity for Waymo to bring our autonomous technology to a global stage," Waymo CEO John Krafcik said. Waymo, Renault and Nissan didn't set a timetable for when their ride-hailing service will launch. They left most other details vague. It seems likely it will still be several years before Waymo will be in a position to pose a serious challenge to Uber, the world's largest ride-hailing service. Although Waymo's self-driving technology is widely considered to be the world's most advanced, it still isn't adept enough to be trusted without a human poised to take control in case something goes awry with the robot. Waymo had hoped to launch a fully autonomous ride-hailing service last year in the Phoenix area, but instead is still keeping human safety drivers in those vehicles more than six months after it rolled out. That service, known as Waymo One, is still only offering rides to a few hundred passengers that previously participated in a test program. Krafcik told the German newspaper Handelsblatt last year that Waymo will likely use a different brand for its ride-hailing services outside the U.S. That could be one reason Waymo is working with France-based Renault and Japan-based Nissan, household names in their home countries. Waymo has previously struck deals with two automakers, Fiat Chrysler and Jaguar, but those involved ordering tens of thousands of vehicles to be equipped with self-driving technology for services in the U.S. So far, Waymo is only using Fiat Chrysler minivans for its Phoenix service. The partnership with Renault and Nissan also involves a long-time alliance they formed with Mitsubishi.

Auditor had questioned Nissan on payments in Ghosn scandal, source says

TOKYO — Nissan's auditor had repeatedly questioned transactions at the heart of allegations of financial misconduct by former chief Carlos Ghosn, but Nissan said they were proper, a person with direct knowledge of the matter said on Wednesday. Ernst & Young ShinNihon LLC questioned Nissan's management several times, chiefly around 2013, about purchases of overseas luxury homes for Ghosn's personal use and of stock-appreciation rights that were conferred on him. But the Japanese automaker said the transactions and financial reporting were appropriate, the source told Reuters on condition of anonymity. The revelation shows Nissan and its auditor were discussing the transactions, in apparent contrast with Nissan's contention that the alleged misreporting of benefits for Ghosn was masterminded by Ghosn and a key lieutenant. A spokesman for EY ShinNihon, the Japanese affiliate of global accounting firm Ernst & Young, said he could not comment on specific cases. A Nissan spokesman declined to comment. Ghosn was arrested on Nov. 19 as he arrived in Japan. Prosecutors accuse him of falsifying Nissan's annual reports to understate by about half his total compensation of some 10 billion yen ($90 million) over several years. The high-profile former executive has denied the allegations, according to Japanese media. Ghosn remains in custody and is unable to speak publicly. He is represented by former prosecutor Motonari Otsuru, according to Japanese media. Otsuru's law firm declined to comment on Wednesday, and Otsuru has not responded to requests for comment. Nissan has largely pinned the blame on Ghosn and Greg Kelly, a former representative director who was arrested along with Ghosn on the same allegations. "As a result of the investigation, we are certain these two are the masterminds," CEO Hiroto Saikawa told a news conference on Nov. 19, referring to Ghosn and Kelly. He declined to say whether others at Nissan were involved in the alleged wrongdoing. An internal investigation is ongoing, and Nissan says it is cooperating with prosecutors. Nissan and Mitsubishi Motors have removed Ghosn as chairman in the wake of his arrest. The French member of the three-firm alliance, Renault, retains him as chairman and CEO.
