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:

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.

2017 Mazda CX-9 packs turbo power, fresh style

After nearly a decade of sales, Mazda finally introduces the second-generation CX-9 crossover. It delivers a comprehensive interior and exterior overhaul, blessing the CX-9 with a powerful, efficient Skyactiv powertrain, and instilling even more of the sporting character that makes Mazdas so darn charming. Like every other vehicle in Mazda's catalog, the CX-9 now wears the handsome, suave stylings of the company's Kodo design language. We think it looks great, but feel free to disagree in Comments. The second-generation CX-9 is the perfect example of Mazda's growing interior design prowess. As is so often the case, it's not so much the style but the choice of materials that stands out. Nappa leather can be paired with real Japanese rosewood and aluminum accents to craft a cabin that feels far more expensive than what you might expect from Mazda. The quality is impressive, even on the pre-pre-production prototypes we tested (drive impressions coming soon). The other headline, aside from the gorgeous interior, is the powertrain. The heart and soul of the operation is a new 2.5-liter, turbocharged Skyactiv engine. Although it only produces a modest 250 horsepower, that figure is complemented by a whopping 310 pound-feet of torque. Importantly, torque is easy to access in the lower part of the rev range, with peak twist coming in at just 2,000 rpm. It drops off rather suddenly north of 4,000 rpm, but as Mazda tells it, most consumers rarely venture above that figure. Mazda expects the CX-9's core market to be perfectly happy with the robust low-end output. A six-speed automatic is responsible for doling out that grunt, and is meant to play nicely with the same i-Activ predictive all-wheel-drive system found in the CX-5 (although the two cars don't share any AWD components). Using 22 different sensors, the system measures road conditions 200 times every second and will even send up to half the engine's power to the rear axle. The entire car, meanwhile, rides on the same Skyactiv architecture as the CX-5 and Mazda6, meaning a multi-link rear suspension has been paired with MacPherson struts up front. Eighteen-inch wheels will be standard, although 20s will also be on offer. You can expect to hear much more on just what the new CX-9 is like to drive next week. Until then, enjoy the official images from Mazda, and keep an eye open for live shots from the LA debut, headed your way soon.
