This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Nissan tests 'self-cleaning' paint on Leaf models in Europe

Once upon a time, self-cleaning ovens were all the rage. Now, Nissan thinks the concept may apply to its vehicles. And the Japanese vehicle maker is testing it out on some of its Leaf battery-electric vehicles Europe, no less. Nissan says its trying out what's called a "superhydrophobic and oleophobic" paint on Leaf battery-electric vehicles for testing and demonstration purposes. The paint, produced by UltraTech International Inc., is designed to repel splats of liquid such as oil or standing water away from the car's surface. The paint, called Ultra-Ever Dry, does this by creating what Nissan says is a layer of air around the vehicle surface. We imagine there's a detailed chemical explanation for this phenomenon that would better explain this process, but that's the best way we can explain it. Right now, Nissan is pitching the product testing as a way to further the Leaf's reputation as what the automaker calls "the world's cleanest car." That said, the paint hasn't been tested in North America, and no plans have been made to add the feature as either a standard or optional goodie for the battery-electric vehicle. Still, go ahead and check out Nissan's press release on the magic paint below. Nissan Creates "World's Cleanest Car" – a Zero Emissions Nissan LEAF with Self-Cleaning Nano-Paint Technology For LEAF owners who never qualify for gas stations' "Free Car Wash with Purchase" offers, this technical study might be the perfect solution July 09, 2014 10:00 AM Eastern Daylight Time NASHVILLE, Tenn.--(BUSINESS WIRE)--What do you get when you combine the world's best-selling zero emission vehicle with innovative paint technology that repels mud, rain and everyday dirt? Answer: A very special Nissan LEAF electric vehicle that might just be the "world's cleanest car." "No matter what the road throws at this LEAF, its Ultra-Ever Dry® exterior coating will throw right back" Created to demonstrate its potential use in future production vehicles, this Nissan LEAF's exterior was treated with a specially engineered superhydrophobic and oleophobic paint that is designed to repel water and oils. The "self-cleaning" paint, called Ultra-Ever Dry®, creates a protective layer of air between the paint and environment, effectively stopping standing water and road spray from creating dirty marks on the LEAF's surface. Nissan is one of the first carmakers to apply this technology to a vehicle.

Ex-Nissan chairman Carlos Ghosn indicted, may remain in jail for months

TOKYO — Nissan's ex-chairman Carlos Ghosn was charged Friday with breach of trust, according to the Tokyo District Court, making the star executive's release unlikely for months. Ghosn, arrested Nov. 19, was earlier charged with falsifying financial reports in underreporting his income by about 5 billion yen ($44 million) over five years through 2015. Ghosn; Greg Kelly, another Nissan executive; and Nissan as a legal entity also were charged Friday with additional underreporting of income, from 2015 through mid-2018. Ghosn's lawyer Motonari Ohtsuru said he would request that Ghosn be granted release on bail. His detention period for the breach of trust allegations was due to expire Friday. Kelly and Nissan were not charged with breach of trust. Those allegations center on Ghosn's handling of investment losses and payments made to a Saudi businessman. Ghosn, 64, says he's innocent. Suspects in Japan are routinely held for months until trials start, and Tokyo prosecutors maintain that Ghosn, a Brazilian-born Frenchman of Lebanese ancestry, is a flight risk. Earlier this week Ghosn told a Tokyo court he was innocent, in his first public appearance since his arrest, and appealed for his detention to end. But the court rejected that request. "I have a genuine love and appreciation for Nissan," Ghosn told the court. "In all of my efforts on behalf of the company, I have acted honorably, legally and with the knowledge and approval of the appropriate executives inside the company." He said the compensation was never decided on, the investment deal never resulted in any losses to Nissan, and the payments to the Saudi businessman were for legitimate services related to dealers and investments in the Gulf. Ghosn, who appeared much thinner than before his arrest, came down with a fever the day after his court appearance, but has since recovered, Ohtsuru, the lawyer, said. His wife Carole Ghosn issued a statement overnight out of Paris, expressing concern over his sickness. "I am pleading with the Japanese authorities to provide us with any information at all about my husband's health. We are fearful and very worried his recovery will be complicated while he continues to endure such harsh conditions and unfair treatment," she said. Apart from prosecutors, only embassy officials and Ghosn's lawyers are allowed to visit him. Such visits were canceled Thursday but resumed Friday.
