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.

Carlos Ghosn changes to hotshot attorney and a new defense strategy

TOKYO — Carlos Ghosn's chief defense attorney Motonari Otsuru resigned and was replaced by a team that includes hotshot lawyer Junichiro Hironaka, in a change of strategy from the ousted Nissan Motor chairman three months after his arrest. Ghosn, Nissan's one-time savior, has been held in detention since his Nov. 19 arrest. He's been indicted and accused of under-reporting his salary and breach of trust. He has denied the charges. The once-feted auto executive hired Hiroshi Kawatsu as head of a new defense team, his office said on Wednesday. Hironaka, 73, has won several high profile cases, helping acquit senior lawmaker Ichiro Ozawa and senior bureaucrat Atsuko Muraki. Hiring Hironaka would mean a more aggressive legal strategy, said Nobuo Gohara, a former prosecutor. Otsuru previously led the special prosecutors' office that is now handling Ghosn's case. "Otsuru was miscast. He worked at the heart of the special prosecutors office so he was not someone who was going to go after them aggressively," Gohara said. "Hironaka is an experienced defense lawyer who has won a number of cases. He will mount a more thorough and aggressive defense." Otsuru's office confirmed his resignation in a statement, but gave no reason for the move. A second member of Ghosn's defense team, Masato Oshikubo, had quit, it said. Go Kondo, Ghosn's third defense lawyer, was unavailable for comment. Ghosn released a short statement thanking Otsuru for his team's "tireless and diligent work," and called him a "very capable and intelligent man and lawyer." The sudden change in attorneys comes ahead of the expected start of informal meetings with prosecutors and judges to discuss pretrial preparations, an indication that there will be no new charges against Ghosn. "As we begin the trial phase, I have decided to engage Hironaka-sensei as my legal counsel," Ghosn said, using an honorific suffix. "I look forward to defending myself vigorously, and this represents the beginning of the process of not only establishing my innocence but also shedding light on the circumstances that led to my unjust detention." Ghosn, 64, told the Nikkei newspaper last month that Nissan executives opposed to his plans for closer ties with automaking partner Renault SA had plotted to remove him. Ghosn was widely credited with rescuing Nissan from near-bankruptcy after he was brought over to Japan in 1999 by Renault after the French automaker bought a chunk of Nissan.

Nissan's Ghosn called out by Deltawing's Panoz in print ad

When the Nissan ZEOD RC limped to the side of the Circuit de la Sarthe a mere five laps into this year's 24 Hours of Le Mans, we imagine that a certain American motorsports figure at least smirked a little. Don Panoz's ongoing feud with Nissan probably means he wasn't sorry to see the arrow-shaped racecar's poor showing, and now he's stepping up his campaign against his former racing partner.
For those who need a refresher, back in 2012, Panoz and Nissan teamed up to field the DeltaWing, an innovative, wedge-shaped racer, as the first entry in the 24 Hours of Le Mans' experimental Garage 56 concept. The car rapidly became a fan favorite. The Panoz/Nissan alliance didn't last, though, and before long, the DeltaWing's designer was getting a paycheck from Nissan and the ZEOD RC racer arrived. Shortly after that, Panoz began mulling over a lawsuit alleging intellectual property infringement. The American motorsports icon would eventually pull the trigger on a suit back in December of 2013.
Panoz's latest move in the ongoing feud involves an open letter in both The Nashville Tennessean, the paper that serves Nissan's US headquarters, and trade paper Automotive News. The letter calls out Renault-Nissan CEO Carlos Ghosn directly, and points out some of the similarities between the DeltaWing and the ZEOD RC, going so far as to quote the original car's designer, Ben Bowlby.
