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:

Mazda MX-30 electric car production begins: Will it get the rotary range extender?

Mazda has officially started production of the electric MX-30. For the time being, the small electric car hasn’t been announced for the U.S. yet. Mazda hasnÂ’t declared otherwise, though, so we still have our hopes up. The first MX-30s are rolling off the line in Hiroshima, Japan. Europe will be one of the first places where these MX-30s end up. The car starts at GBP30,495 in the UK and ˆ33,990 in Germany. That's around $38,000. Certainly expensive, but the price would surely be different here, plus weÂ’d be eligible for the full $7,500 tax credit. Those lucky European customers will be met with an electric car that likes to do things a little differently than others. The modest 35.5 kWh battery pack is good for just 124 miles on EuropeÂ’s optimistic WLTP testing cycle. It would surely achieve a much lower number in the EPA test. Mazda has made it front-wheel drive, placing a single motor on the front axle thatÂ’s good for 143 horsepower. We expect to see the first ones hit the streets in Europe this fall, but thereÂ’s one thing that makes us hold out hope for an American MX-30: the potential for a rotary range extender. Mazda said as much in its 100-year celebration letter: “Later, the company developed a prototype Mazda2 EV with a small single-rotor engine used as a range extender. A similar system could find its way onto the Mazda MX-30, a brand new battery electric crossover SUV arriving at dealerships this year." Assuming Mazda goes through with a rotary range extender, we could see this car coming to the American market. That would up the range considerably and make it a much more viable option for many customers, even if they might not need the added range on a daily basis.  Related video:

Mazda Furai concept designer talks about his car's passing

Last week, there was mourning at the Autoblog offices as word trickled in that the Mazda Furai concept - one of the coolest, best-looking showcars to grace an auto show stage since the wild and crazy 1960s -had been killed. It was killed on the track with the folks from Top Gear in attendance. We're sure the gods of driving would have wanted it to die on a circuit, but that doesn't make its fiery passing any easier to deal with.
The Furai is the rare concept car that had a lasting appeal with enthusiasts, partly because it was a real, functioning racecar, complete with a wacky three-rotor Wankel engine and cutting-edge Nagare design. Now that it's gone, though, Road & Track's Mallory McMorrow, who was an intern at Mazda Design when the Furai was being styled in 2007, has published an interview with one of the men who penned the Mazda showcar's striking exterior, Carlos Salaff. It's a great piece on the emotional connection between a designer and his creation, and one you should take the time to read. Click on over to R&T for the full story.
