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.

Infiniti Q50 Eau Rouge gets the heart of a GT-R [w/video]

There has been ongoing talk of an Infiniti using the Nissan GT-R powertrain practically since the moment the Nissan's flagship sports coupe hit the road. While the rumors have gone back and forth over the years, they have never completely gone away. It seems Infiniti is finally turning an ear to the screams of its most vocal enthusiasts with an updated version of the Q50 Eau Rouge concept boasting a modified version of Godzilla's engine and all-wheel drive system debuting at the 2014 Geneva Motor Show. It's even taking things a step further and granting it a new, seven-speed transmission to replace the Nissan's six-speed.
The latest evolution of the Eau Rouge packs the same 3.8-liter, twin turbocharged V6 found in the GT-R but with a unique tune of 560 horsepower and 443 pound-feet (600 Newton-meters) of torque. That makes it 15 hp more powerful than the standard 2015 GT-R but gives up 20 lb-ft of torque. Power gets to the ground through the GT-R's all-wheel-drive system. Infiniti predicts that the Eau Rouge would sprint to 60 miles per hour in less than 4 seconds and on to a top speed of 180 mph.
According to Infiniti Communications Senior Manager Kyle Bazemore in an email to Autoblog, the modded GT-R powertrain was not the only choice for the Eau Rouge. It also considered "developing a high-power sports diesel" and hybrid versions with an electric supercharger. However, "this was the clear solution for this concept car," Bazemore said. Other than the drivetrain, the Eau Rouge in Switzerland is identical to the one shown in Detroit. Sadly, it is not confirmed for production; so we might not be getting the fabled Infiniti GT-R sedan any time soon. Still, we can hope.

Macron and Abe seek to avert messy Renault-Nissan breakup

TOKYO/PARIS – France and Japan's leaders met for bilateral talks to avert a diplomatic row over the Renault-Nissan-Mitsubishi alliance on Friday following the surprise arrest of its Chairman Carlos Ghosn in Japan. With the carmaking alliance facing its biggest test after the ousting of Ghosn at Nissan and affiliate Mitsubishi over financial misconduct allegations, President Emmanuel Macron sat down with Prime Minister Shinzo Abe at the G20 summit in Buenos Aires. Ghosn's arrest to face accusations including the under-reporting of income has triggered new attempts by Nissan to weaken Renault's control of the Franco-Japanese alliance, adding to challenges facing Macron at home. Macron, whose government has repeatedly pressed Japan to share evidence unearthed by Nissan's internal investigation into Ghosn, "restated his firm wish that the alliance should be preserved, along with the stability of the group," an Elysee official said after Friday's meeting with Abe. Abe said it was important to "maintain a stable relationship," according to a spokesman for the Japanese leader. "However, he said the future of the alliance is up to the private-sector shareholders. The government of Japan does not prejudge the future of the alliance," the spokesman said. The French official quoted Abe as telling Macron that "the legal process must be allowed to take its course." LEADERLESS Tokyo authorities on Friday extended Ghosn's detention for a second time, by the maximum-allowed 10 days, local media reported. Prosecutors must file charges by Dec. 10 or arrest Ghosn for new crimes to hold him beyond that date. Tokyo prosecutors declined to comment. Nissan did not immediately respond to a request for comment. Ghosn's detention has left the global auto alliance without its leader and main interlocutor with the French government, which owns 15 percent of Renault and wants to maintain the ownership structure enshrining its control of the partnership. But Nissan Chief Executive Hiroto Saikawa has made clear that Nissan wants to weaken the control of its smaller parent as it carries out a governance review. Renault's 43.4 percent Nissan stake ensures an effective voting majority at shareholder meetings, while Nissan's reciprocal 15 percent Renault holding carries no voting rights.
