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:

Recharge Wrap-up: Nissan Leaf top environmental performer, 50,000th Renault Zoe

Renault has produced its 50,000th Zoe electric car. A Frenchwoman named Sylvie took ownership of the milestone vehicle at the Flins plant where it rolled of the line. She says her children helped convince her to buy the all-electric vehicle, which Sylvie intends to use as a daily driver. The Renault Zoe is Europe's best selling EV since its launch in 2013. Renault reports a 98-percent satisfaction rate with the Zoe. Read more in the press release from Renault. Toyota will use a biosynthetic rubber called biohydrin in its engine and drive system hoses beginning in May 2016. Jointly developed by Toyota, biohydrin is a plant-based rubber with a 20-percent reduction in material lifecycle carbon emissions compared to petroleum-based rubber. Toyota plans to use the compound in even more components in the future, including brake and fuel line hoses. Read more from Toyota. So far in 2016, only 27.5 percent of hybrids and EVs are traded in for another electrified vehicle, according to Edmunds. That's down from 38.5 percent in 2015. 33.8 percent of electrified vehicles are traded in for SUVs. Despite the trend of EV and hybrid owners switching back to traditionally powered vehicles, average fuel economy isn't suffering. "This is an economics trend, since today's low cost of gas no longer makes it worth paying the price premium of hybrids and EVs," says Edmunds Director of Industry Analysis Jessica Caldwell. "And there are so many fuel-efficient vehicles on the market today that environmental concerns weigh less than they might have in years past. When you're buying a vehicle that can get over 30 mpg, you can still say you're doing your part to help the environment." Read more from Edmunds. Environmentally, electrified vehicles outperform their conventional combustion counterparts throughout their lifecycle. A study from the Automotive Science Group (ASG) finds that while production of advanced powertrains comes with a greater financial burden, most vehicles make up for it through efficiencies during their use phase. The ASG lists the 2016 Nissan Leaf as its best performer, with 47 percent fewer greenhouse gas emissions than the best-performing conventionally powered car, the Honda Fit. Rounding out the ASG's top five environmental performers are the Ford Focus Electric, Chevrolet Volt, Toyota Prius Two Eco, and Hyundai Sonata Plug-In Hybrid.

Nissan CEO Makoto Uchida rules out closer capital ties with Renault

YOKOHAMA — Nissan is committed to its automaking alliance with Renault but will not look to deepen its capital ties with the French automaker any time soon, its new CEO said on Monday. On his first day in the new position, chief executive Makoto Uchida also pledged to repair profitability at Japan's No. 2 automaker and said setting realistic targets would be key toward that goal, as it tries to make a clean break from the leadership of former chairman Carlos Ghosn. "Closer capital ties with Renault are not a focus in the short term," he told reporters. Uchida became CEO of Nissan on Dec. 1, as the car maker tries to recover from a profit slump and draw a line under a year of turmoil after the Ghosn scandal. The ousted chairman is fighting financial misconduct charges in Japan. One of the new CEO's big tasks is to salvage ties with Renault, which have deteriorated since Ghosn's ouster as chairman of both companies. Renault holds a 43.4% stake in Nissan after it saved the Japanese automaker from financial ruin two decades ago, and has pushed for the two companies to merge. In rejecting a notion of a merger with Renault, Uchida, 53, echoes his predecessor Hiroto Saikawa, who stepped down in September. He added that the alliance must re-think how it can serve all of its three members, which also includes Mitsubishi Motors. "The alliance has to benefit each of its partners in terms of revenue and profit," he said. "We need to re-evaluate what has worked and what hasn't worked in the alliance in the past few years." The CEO called for Nissan to set "challenging but achievable" targets, adding that this and the launch of more new car models and vehicle technologies would be key to its financial recovery. Nissan is bracing for its lowest annual profit in 11 years and has slashed its dividend by 65%. Its struggles come at a time when car companies desperately need scale to keep up with sweeping technological changes like electric vehicles and ride-hailing. "Somewhere along the way we created a culture of setting targets which could not be achieved," Uchida said, adding that this had resulted in a focus on short-term results. "Years of this had led Nissan to its current "difficult situation," he said, using heavy vehicle discounting in the U.S. market as an example of how aggressive sales targets to grow market share had deteriorated the company's brand.
