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 didn't have much say in merger talks, but it had what FCA wanted

TOKYO — Nissan wasn't consulted on the proposed merger between its alliance partner Renault and Fiat Chrysler, but the Japanese automaker's reluctance to go along may have helped bring about the surprise collapse of the talks. While Nissan Motor Co. had a weaker bargaining position from the start, with its financial performance crumbling after the arrest last year of its star executive Carlos Ghosn, it still had as its crown jewel the technology of electric vehicles and hybrids that Fiat Chrysler wanted. The board of Renault, meeting Thursday, didn't get as far as voting on the proposal, announced last week, which would have created the world's third biggest automaker, trailing only Volkswagen AG of Germany and Japan's Toyota Motor Corp. When the French government, Renault's top shareholder with a 15% stake, asked for more time to convince Nissan, Fiat Chrysler Chairman John Elkann abruptly withdrew the offer. Although analysts say reviving the talks isn't out of the question, they say trust among the players appears to have been broken. "The other companies made the mistake of underestimating Nissan's determination to say, 'No,' " said Katsuya Takeuchi, senior analyst at Mitsubishi UFJ Morgan Stanley Securities in Tokyo. The Note, an electric car with a small gas engine to charge its battery, was Japan's No. 1 selling car, the first time in 50 years that a Nissan beat Toyota and Honda. Renault and Fiat Chrysler highlighted possible synergies that come from sharing parts and research costs as the benefits of the merger. But what Fiat Chrysler lacks and really wanted was what's called in the industry "electrification technology," Takeuchi said. With emissions regulations getting stricter around the world, having such technology is crucial. Yokohama-based Nissan makes the world's best-selling electric car Leaf. Its Note, an electric car equipped with a small gas engine to charge its battery, was Japan's No. 1 selling car for the fiscal year through March, the first time in 50 years that a Nissan model beat Toyota and Honda Motor Co. for that title. Nissan is also a leader in autonomous-driving technology, another area all the automakers are trying to innovate. "Although Nissan had no say, its cautionary stance on the merger ended up being very meaningful," Takeuchi said.

NA auto output to reach 11-year peak

According to Automotive News, automakers are expected to manufacture 16 million light vehicles in North America in 2013. That's up 500,000 units from last year and marks the largest number since 2002. The prediction comes courtesy of LMC Automotive and IHS Automotive, which point to the improving US economy as a bellwether for total production. LMC Automotive says North America will produce 16 million vehicles while IHS has a slightly more optimistic forecast of 16.1 million units. A total of seven automakers are slated to increase production on the continent this year. Nissan is set to see the largest jump at 20 percent over last year.
Volkswagen, meanwhile, is one of the only manufacturers predicted to scale back production. Analysts expect the German company's output to fall by 23 percent to 170,000 units, thanks in part to slow demand for the Volkswagen Passat and Jetta.
