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:

Flyin' Miata's 525-hp V8-powered ND finally hits the streets

Flyin' Miata, in its valiant quest to turn Mazda's roadsters into small, Japanese Corvettes, has finally finished its first V8-powered ND Miata. The company has been slowly teasing us with images and videos for months, but it wasn't until this week that the car finally made it to the streets. As soon as the current ND generation Miata was released, Flyin' Miata started the work to shoehorn a GM LS3 under the hood. The company has a history of building brutish, V8-powered Miatas. It sells everything from minor parts to full V8 conversion kits. For those with the cash that prefer to avoid the hassle, Flyin' Miata will sell you a complete, turn-key car. The price hasn't been finalized, but customers should expect to pay about $50,000 plus the cost of the MX-5. The new car has a worked-over LS3 that sends 525 horsepower to the rear wheels through a Tremec T56 transmission. Flyin' Miata says the rear differential comes from a V8 Camaro. Other new bits include exhaust, suspension, brakes, and a roll cage. Flyin' Miata tells us that the V8-swapped ND will weigh 2,592 lbs, a little more than 200 lbs more than the porkiest stock Miata. Despite twice as many cylinders and more than three times the displacement of the stock four banger, the LS3 V8 is a relatively small and lightweight engine. The finished car has a 53:47 front to rear weight distribution. Final touches are being finished, but cars and kits should be available soon. This article has been updated with some info straight from Flyin' Miata. Thanks, Keith! Related Video: News Source: Road & Track, Flyin' Miata Mazda Convertible Performance flyin miata
