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:

Williams developing hybrid system for next Nissan GT-R?

Back in June, Nissan announced a new partnership with Williams that would see the Formula One team's applied sciences division help develop a new line of Nismo performance models. It's not the only agreement Renault-Nissan has signed with an F1 team: Infiniti is the title sponsor for Red Bull and Renault powers four teams on the grid. It's also just the latest client Williams has signed a deal with to apply the lessons it has gleaned on the F1 circuit to other racing and sportscars. But now we've got some more info on how Williams and Nismo intend to collaborate on the next-generation GT-R.
According to Australia's Carsales, Williams Advanced Engineering is developing the hybrid powertrain that will boost the next iteration of the supercar-slayer known as Godzilla. Which may seem strange considering that the Renault-Nissan Alliance has plenty of experience with electric propulsion on its own, but then Williams has proven itself something of a leader in the field of performance hybrid powertrains: it supplies them to Porsche and Audi for their Le Mans racecars, and to Jaguar for the C-X75 concept.
Whether Williams and Nismo will settle on a flywheel-based energy recovery system or a more conventional battery-powered system remains to be seen, but brakeforce regeneration likely won't be the only element that Williams will develop for the next GT-R. Expect its expertise in aerodynamics and composites to come to bear as well, which can only mean good things for the replacement for a sportscar that's already one of the most capable on the road.

Renault, Nissan attempt to calm rumors of impending split

TOKYO/PARIS — Shares in Renault recovered some lost ground on Tuesday after the French carmaker and its Japanese partner Nissan rejected media reports that their alliance was in danger of being dissolved. Some have openly questioned whether the alliance can survive without disgraced former CEO Carlos Ghosn to keep the two partners happy.  Renault shares fell to a six-year low on Monday after rumors circulated that its alliance with Nissan was in jeopardy. Nissan shares tumbled to their lowest in 8 1/2 years on Tuesday in Tokyo. At the opening of trading in Paris on Tuesday, Renault shares rose 1.3 percent, before falling back slightly to trade up 0.49 percent by 08:23 GMT. The alliance, which also includes Japan's Mitsubishi Motors, is "solid, robust, everything but dead," the chairman of Renault, Jean-Philippe Senard, told Belgian newspaper L'Echo. A split between the two automotive giants would force both to find new partners in a fast-consolidating industry that is growing increasingly difficult to navigate for independent companies. It will be especially difficult for Renault and Nissan, whose dirty laundry Ghosn intends to air for public consideration.   French Finance Minister Bruno Le Maire also weighed in, saying reports some executives wanted to break up the alliance were "malicious." Speaking to France's CNews TV, he also said he expected Renault to name a new chief executive within days to replace Thierry Bollore, a Ghosn-era appointee who was ousted in October. Luca de Meo, who stepped down as the head of Volkswagen's Seat brand last week, is seen as a frontrunner for the job, although a stringent non-compete clause in his contract firm may prove a hurdle, sources have told Reuters. Nissan, in response to "speculative international media reports," said it was "in no way considering dissolving the alliance." "The alliance is the source of Nissan's competitiveness," the Japanese automaker said in a statement. "Through the alliance, to achieve sustainable and profitable growth, Nissan will look to continue delivering win-win results for all member companies." Concerns emerged about the future of the Renault-Nissan partnership after the November 2018 arrest in Japan of Ghosn, the man who did more than anyone else to hold together the disparate alliance of often-contrasting carmaking cultures.
