Mazda3 to showcase CNG, Hybrid versions in Tokyo

Mazda has made huge gains in its competitive set with the introduction of its Skyactiv technologies, and the Japanese automaker appears to have no plans on slowing down. While we're still waiting for the Mazda6 Skyactiv-D diesel to go on sale in the US, Mazda announced that it will debut new Skyactiv-Hybrid and Skyactiv-CNG versions of the Mazda3 (standard US-spec model shown above) at next month's Tokyo Motor Show.
Matching up with what we heard earlier in the summer, the Mazda3 Skyactiv-Hybrid is intended for Japan only, but there are no details about this system regarding fuel economy, electric components or specs. Likewise, there are no details for the Mazda3 Skyactiv-CNG Concept, which is a bi-fuel version of the car running on both gasoline and compressed natural gas. As this car's name suggests, the CNG model is a concept vehicle, and there is no indication that Mazda plans offering such a model here in the US.
In addition to these two vehicles, Mazda will also have an Atenza (Mazda6) on display showing off some vehicle-to-vehicle (V2V) safety systems, called the ASV-5 (Advanced Safety Vehicle). Scroll down for Mazda's official press release.

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:

Mazda6 Skyactiv-D racecar gets first win at Road Atlanta

Mazda has a long motorsports history, and one that is peppered with fascinating cars. The latest chapter in Mazda's racing story has just been written, as Joel Miller and Andrew Carbonell have driven the Visit Florida Racing Mazda6 Skyactiv-D to the car's first ever victory at the Rolex Grand-Am GX race at Road Atlanta. The win marks the first ever for Mazda's diesel-burning, production-car based Skyactiv-D racer, and the first win for a diesel-powered car in a Grand-Am event.
In fact, it was a particularly good day for the Mazda Motorsports team, as a Mazda6 also picked up the third finishing spot at Road Atlanta. Director of Mazda Motorsports, John M. Doonan, said of the racecar, "We've always said that the best street cars make the best racecars, and, with more than half of the components in the race engine being shared with the street engine, this program is a solid proof-point."
SpeedSource Engineering, which helped to build the Mazda6 racer, was greatly heartened by the car's performance in just it's fourth-ever race. Owner Sylvain Tremblay called the victory, "a tribute to the thousands of hours of hard work over many months," continuing, "The normal plan with a new car is to spend the first year in development, the second year seeking race wins, and challenging for a championship in year three. We are already at our year-two status after four races. We can't wait to get to the Belle Isle course in Detroit for round five."
