Nissan Leaf sales get January jump as Chevy Volt trends downward

The cold January sales dip hit both the Nissan Leaf and the Chevy Volt last month, but when compared 2014 to 2013's first-month-of-the-year sales totals, one of the two early plug-in vehicles obviously came out on top. The top Leaf market also shifted away from Atlanta for the first time in months. Last year, the Leaf sold just 650 units in January, but it managed to move 1,252 last month, a 92.6-percent increase over 2013 but a big drop from the 2,529 sold in December 2013. Paige Presley over at Nissan told AutoblogGreen that the Leaf has now broken sales records for 11 months straight and that, "we see unique seasonality with some December pull-ahead demand based on federal and state tax incentives." The number one Leaf market also shifted away from Atlanta for the first time in months, moving back to San Francisco. That change could be short-lived. "We had some inventory constraint issues early in the month in Atlanta with end-of-year demand depleting stock," Presley said. "By the time we resolved that, the weather hampered sales." There was not as much good news on the Chevrolet front. Last month, the Volt sold 918 units, down from 1,140 in January 2013 and 2,392 in December 2013. It also marks the first time the Volt has sold in the three-digit range since January 2012, when it sold 603 copies. That string of solid months means that the plug-in hybrid has a roughly 12,000-unit lead over the EV since the two cars brought plug-in vehicles back to the mass market all the way back in December 2010. We will have our full report of January's green car sales up soon.

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.
