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:

Recharge Wrap-up: First EV to attempt Dakar Rally, Mazda makes bioplastic parts

Zap and Jonway Auto brought their Urbee EV and their new Falcon A-380 SUV to the Peru Motor Show in Lima. Jonway sells its SUV and minivan in Lima through Dai-Ichi Motors, which displayed the cars at the show. According to the companies, their cars "received tremendous interest from the public," including private citizens as well as groups who would use the EVs for security guard service or campus use.

The state boasts almost half of the country's electric vehicles, thanks largely to state and local EV incentives that go beyond the federal tax rebate. California also leads the way in legislation, and nine other states have adopted California's ZEV mandate. Washington, Maryland, Georgia and DC also have their own EV incentives, while some utility companies also offer benefits for EV owners in other states. Still, EV sales have only made up about 0.7 percent of new vehicle sales in 2014. Read more at the US Energy Information Administration website. Toyota will be using landfill gas to help power its Kentucky manufacturing facility. Beginning in 2015, Toyota's Georgetown assembly plant will use electricity converted from landfill-sourced methane gas from Waste Services of the Bluegrass. It will provide enough energy to produce 10,000 vehicles each year. Plus it diverts methane - a greenhouse gas - from entering the atmosphere and helps improve the local air quality. Learn more in the video or Toyota's press release below. Mazda has developed a plant-derived bioplastic for making exterior and interior parts. The dyed plastic doesn't require painting, and it reduces petroleum consumption and carbon emissions in the manufacturing process. The bioplastic will be used for interior parts in the all-new MX-5 before being put into use on the exterior of future vehicles. Mazda will display prototype parts at the Eco-Products 2014 exhibit in Tokyo. Read more in the press release below. Acciona will enter the first-ever zero-emissions vehicle (pictured) to compete in the Dakar Rally. The vehicle uses an electric motor and lithium ion batteries, as well as solar panels to power telemetry and security systems. The Dakar Rally will take place from January 4 through 17 through Argentina, Chile and Bolivia. See Acciona's Dakar EV in the video and read more in the press release below.

Our Mazda MX-5 Miata has the best engine bay in the business

One of the things that's really disappointing about modern cars is how they all hide their technology under a proverbial bushel. You pop the hood, and nine times out of 10, you're faced with some amount of black plastic hiding the functional bits. On some cars the plastic covers the bare minimum to have a "presentable" engine. Others have every tank, hose, wire and screw buried under a layer of smooth plastic. Few exemplify this practice better than engine bay of the current Lexus LS 460, seen below. If Lexus was this embarrassed about its engine, maybe it should have simply bolted the hood shut. However, like with weight gain and power creep, our fourth-generation Mazda MX-5 Miata bucks the plastic trend. Lift the aluminum hood of the little roadster, and you travel back in time more than a decade. (See the gallery up top.) Only one bit of decorative plastic is in sight, and it proclaims the car's Skyactiv technology and hides some of the wires leading to the ignition coils. Otherwise, nothing else is obscured. The shock tower braces, manifolds, battery terminals, the whole shebang is all right there for you to see. What's particularly amazing is that it all looks good. Even in some cars that eschew plastic covers, it's no guarantee of an attractive engine bay. We just had a new Honda Civic Sport hatchback (seen immediately above), and while it doesn't sport a plastic engine cover, you can see from the photo that it's not particularly attractive with tubes and cables snaking every which way. But in the Miata, the hoses and wires are kept to a minimum, and the ones that are there are arranged in a way that isn't haphazard or tangled. Then, in the middle, there's the clean, simple aluminum cam cover as the gleaming centerpiece, similar to those of the first- and second-generation cars. As the owner of a '99 Miata, this detail in particular gives me the warm fuzzies. The fully exposed engine bay fits with the Miata's personality. The car is very straightforward, it features just the absolute minimum of style and comfort additions, and is highly accessible. I would say the Miata's engine bay is the window to its soul, if driving it didn't offer a clearer picture. Related Video:
