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:

Nissan won't downsize the next Armada

The Nissan Armada is aptly named, because in relative automotive terms, it's not just the size of a ship - it's the size of a whole fleet. And that, according to reports, isn't about to change.
While many of the larger SUVs on the market are gradually being phased out or replaced by smaller crossovers, Nissan apparently plans on keeping the Armada right where it is. And that means a large, truck-based, eight-passenger colossus, because there are buyers out there who expect no less and Nissan isn't about to lose them to the likes of the Toyota Sequoia, Ford Expedition and Lincoln Navigator, or a General Motors lineup that includes the Chevy Suburban and Tahoe, GMC Yukon and Cadillac Escalade.
That doesn't mean that the next Armada - which Edmunds expects will arrive in 2015 or 2016 - will be immune to constricting environmental regulations, so Nissan will have to get creative. A vehicle the size of the Armada has all the aerodynamic efficiency of the side of a barn, but Nissan is reportedly aiming to streamline that in order to boost efficiency, for starters.

Recharge Wrap-up: Tesla Model X 0-100 video, Nissan-Renault record EV sales

A video shows that a Tesla Model X can accelerate from 0-100 mph faster than a Model S P85D. DragTimes tested a Founders Edition Tesla Model X P90D with Ludicrous Mode, and found that it did 0-60 mph in 3.178 seconds, which is faster than Tesla's stated 3.2 seconds. The 0-100 mph happened in just 7.98 seconds, which is faster than the 8.3 seconds DragTimes clocked in Model S P85D using Insane Mode. Even more impressive is that the Model X used is a seven-seater with all the boxes ticked, which means that it's lugging a lot of extra weight on the drag strip. DragTimes says it intends to do more tests with other configurations of Tesla models – perhaps we'll get to see how two vehicles with Ludicrous Mode compare. See the video above, and read more at Teslarati. Nissan and Renault saw record sales of electric vehicles in 2015. The two automakers sold 84,754 battery-powered vehicles last year, a rise of 2.5 percent. Nissan Leaf and e-NV200 sales dropped by almost 10 percent, but Leaf sales are expected to improve with the next generation. The Alliance's EV sales, though, were boosted by Renault selling 45 percent more EVs in 2015. Government incentives in France are partially responsible for Renault's success. Since they began selling them, Renault and Nissan have sold 302,000 EVs worldwide by the end of 2015. Read more at Bloomberg Business. A study finds that E20 provides higher peak load capability and thermal efficiency than gasoline in reactivity-controlled compression ignition (RCCI) combustion. The dual-fuel combustion technique uses in-cylinder blending to optimize combustion. The study used E20 ethanol blend or gasoline blended with highway diesel or B20 biodiesel blend and compared the results. In addition to the load capacity and thermal efficiency benefits, E20 also produced fewer hydrocarbon emissions. Read more at Green Car Congress.
