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 diesel may finally launch this year according to CARB certification

For close to a decade, Mazda said it would bring its latest generation of diesel engine, Skyactiv-D, to the United States. And for most of that time, it said that engine would appear in the Mazda6. Last year Mazda finally brought us the engine in the CX-5, and it looks like this year, the 6 will finally get it, too. This seems to be the case based on a CARB certification posted on January 31 specifically for the midsize family sedan. The CX-5, in both front-wheel- and all-wheel-drive variants, is listed in a different certification, so it's not a case of a blanket certification for every vehicle the engine could appear in this year. As expected, the document lists the 6 as having a 2.2-liter turbocharged engine with a six-speed automatic, though it doesn't say whether the model is front-wheel-drive or all-wheel. Either is certainly possible, since all-wheel drive, in particular with the diesel, is available in overseas Mazda6s. Like in the CX-5, the engine will probably make 168 horsepower and 290 pound-feet of torque. While this certification tells us the diesel 6 will probably launch this year as a 2021 model, we're left to estimate the reveal date. Midway through the year, or possibly at the start of the next auto show cycle would seem likely, which would coincide with a model year update. Mazda has stated it will only be offered on the top-tier Signature trim, which starts at $36,345 with the standard turbocharged gasoline 4-cylinder. Looking at the price difference between a turbocharged Mazda CX-5 Signature with all-wheel-drive and the diesel CX-5, the price difference is about $4,000, so it would seem reasonable to expect the Mazda6 diesel to ring in at about $40,000.

Preorders open for the Mazda MX-5 Miata RF Launch Edition

After unveiling the gorgeous 2017 Mazda MX-5 Miata RF Launch Edition at the 2016 New York International Auto Show, the Japanese automaker announced plans to give loyal customers first dibs on one of the 1,000 models. Preorders are open at 12 PM EST on Monday, September 26th at the Mazda MX-5 RF Launch Edition website. Customers who were sent an invitation with a personalized code will have a limited time to put a $500 refundable deposit down on a limited model. Customers also have the opportunity to select the dealership where they would like to complete the transaction. Pricing for the MX-5 RF has also been announced with the sports car starting at $34,685, including destination and handling. That's roughly $9,000 more than a base MX-5 Miata. Deliveries of the sports car will begin in February 2017. While the MX-5 RF is a looker, $9,000 is a lot of change for the Launch Edition, which only adds a black roof and special badges over the regular MX-5 RF models. All 1,000 Launch Editions will be finished in Machine Gray with a black roof panel and Auburn Nappa leather on the inside. Buyers who opt for the Launch Edition will also get a numbered 42mm Tourneau watch, and can choose between an automatic and a manual transmission. The MX-5 RF Launch Edition should sell out quickly, as the 2015 Mazda MX-5 25th Anniversary Edition sold out in roughly 10 minutes when it went on sale in 2014. Didn't get an invite to preorder the Launch Edition? Worry not, as Mazda will open the special model to the general public on October 3, if there are any left.
