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:

Next-gen Mazda MX-5 Miata mule spied 'Ring testing

Fans of simple, lightweight motoring, rejoice - we now have images of the next-generation Mazda MX-5 Miata undergoing testing at der Nürburgring Nordschleife. Now, to be fair, this isn't some lightly camouflaged example that will give us a great peak of what the next Miata, which will also become the next Alfa Romeo Spider, will look like. This is a mule, with the new bits hidden under a current Miata's body. That doesn't mean there aren't a few scraps of valuable information here, though.
According to our flock of camera-toting spies at the Nürburgring, the next Miata is likely to grow a bit, as new models are wont to do. In particular, it will be longer and wider, and the wheelbase is likely going to be stretched, based on the shape of the wheel wells and doors. Both of those factors will add more space in the cabin.
Those are the big indications provided by these photos, but while the MX-5 might be growing, it's a safe bet based on these images that it, and the (likely pricier) Alfa, will retain the classic, long-hood, short-deck styling that so typifies rear-drive roadsters.
