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 shows off Le Mans Prototype, says it's world's fastest electric racer [w/video]

Nissan has announced plans and details around its upcoming all-electric racing car, the ZEOD RC. The Zero Emission On Demand Racing car is said to be capable of a top speed in excess of 300 kilometers per hour (186.4 miles per hour), is shaped a bit like the closed-cockpit version of the DeltaWing (albeit, to our eyes, better looking) and will make its debut in 2014 at the 24 Hours of Le Mans. This weekend, visitors to the race will have the opportunity to view the prototype near the Circuit de la Sarthe.
Nissan's ZEOD RC has been invited by Le Mans organizers to compete as the Garage 56 entry in next year's race; that's essentially a spot on the grid held for vehicles with new and/or cutting edge technology.
Short of announcing a partnership with Michelin to develop tires for the EV racecar, however, Nissan is mum on any kind of battery or motor specification for the ZEOD. The press release (below) offers a sense that the Nissan and Nismo teams have still got a lot of work to do before the 2014 race. Ben Bowlby, designer of the ZEOD RC, says "We have many options to consider and test. The test program is part of a longer term goal of developing a system and a set of rules for this type of technology in partnership with the ACO that would be best suited to competing at the highest level of this sport."

Tokyo court rejects Carlos Ghosn's bail request

TOKYO — A Tokyo court rejected former Nissan chairman Carlos Ghosn's latest request for bail on Tuesday, more than two months after his arrest. A statement from the Tokyo District Court announcing its decision gave no explanation for prolonging a detention of the 64-year-old executive, which has drawn international scrutiny of Japan's justice system. Ghosn had promised to wear an electronic monitoring ankle bracelet, give up his passport and pay for security guards approved by prosecutors in his latest attempt to gain release from a Tokyo detention center. His family said they will appeal. Ghosn has been in custody since Nov. 19. He had a bail hearing Monday. A Tokyo court rejected an earlier request for bail last week. Ghosn, who led Nissan Motor Co. for two decades, has been charged with falsifying financial reports in underreporting his compensation from Nissan over eight years, and with breach of trust, centering on allegations Ghosn had Nissan temporarily shoulder his personal investment losses and pay a Saudi businessman. Ghosn has said he is innocent, explaining that the alleged compensation was never decided, Nissan didn't suffer losses and the payment was for legitimate services. His wife, Carole Ghosn, appealed for his release through Human Rights Watch earlier this month, saying Ghosn's treatment has been harsh and unfair. Her views echo widespread criticism of Japan's criminal justice system both inside and outside Japan. Suspects who insist they are innocent get held longer. Suspects are held in a cell and routinely grilled daily by investigators without a lawyer present, although lawyers are allowed to visit. Ghosn's lawyer Motonari Ohtsuru has acknowledged Ghosn's release may not come until the trial, which may be six months away. A date for the trial has not been set. Nissan officials say an internal investigation has found that Ghosn had schemes to hide his income and that he used company money and assets for personal gain. A special committee Nissan set up after Ghosn's arrest to strengthen governance held its first meeting Sunday. Seiichiro Nishioka, a former judge and co-chair, told reporters after the meeting that Ghosn had shown questionable ethics, and too much power within the company had been focused in one person. The committee's findings are due by late March. Ghosn's pay was long a sticking point in Japan, where executives generally get paid far less than their American and other Western counterparts.
