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:

Teen Miata enthusiast and friend of Autoblog passes away

When Thomas' illness made it impossible for him to drive, he relied on friends to do it for him.
Attending the reveal of the 2016 MX-5 Miata and the subsequent 25th anniversary celebration at Mazda Raceway Laguna Seca confirmed that the little roadster maintains broad appeal, one not limited to the elderly or a certain gender as detractors might have you believe. In fact, the assembled crowd was surprisingly youthful, particularly amongst the club racer set and tuners. But one young Miata owner and superfan unfortunately wasn't in attendance - Thomas Jost, 19, was busy fighting for his life in a Maryland hospital.

Goodwood Festival of Speed celebrating Mazda this year [w/video]

Mazda gets to wear the crown and sash as the doubly honored marque for the Goodwood Festival of Speed this year. The Japanese brand will be the focus of the Central Feature, the sculpture that sits outside Goodwood House, and its race cars will be the focus on the lawn, where there will be at least one representative from "every era of Mazda's motor sport achievement." The theme for this year's event is "Flat-out and fearless: racing on the edge." The showcase, of course, will be the 700-horsepower, rotary-engined 787B that won the 24 Hours of Le Mans in 1991. It will run up the 1.6-mile Hillclimb while a Mazda challenger from the World Rally Championship runs the Forest Rally Stage, joining Andros Trophy ice racing and sportscar racing Mazdas. The festival happens from June 25-28 this year, and there's a press release with more details down below the video recap from 2014 and Mazda 787B Le Mans lap. This content is hosted by a third party.
