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's Carlos Ghosn offers to wear electronic ankle tag if released

TOKYO — Ousted Nissan Chairman Carlos Ghosn has offered to wear an electronic ankle tag and hire guards to monitor him in an unusual bid to secure his release on bail after two months of harsh detention in Japan for alleged financial crimes. Ghosn is also willing to remain in Tokyo, where he has leased an apartment, and post stock he owns in Nissan as collateral, his spokeswoman said. A new bail hearing is set for Monday after an earlier request was denied due partly to concerns the French executive was a flight risk. His release would allow Ghosn to meet more frequently with his lawyers and defend himself before the board of Renault, where he remains chairman and CEO, amid calls for his removal and potential moves to restructure the Nissan tie-up. Ghosn denies any wrongdoing as he awaits trial on charges of financial misconduct. "I will attend my trial not only because I am legally obligated to do so, but because I am eager to finally have the opportunity to defend myself," Ghosn said in a statement on Sunday. "I am not guilty of the charges against me, and I look forward to defending my reputation in the courtroom." Meanwhile, Ghosn's wife, Carole Ghosn, has written to French President Emmanuel Macron to discuss her husband's situation, her public relations representative said. The representative, Devon Spurgeon, confirmed a report in French paper Journal du Dimanche that a letter had been sent to Macron this month, but declined to provide details. France wants a full merger As Ghosn's arrest on Nov. 19 continued to cloud the outlook for Nissan's three-way alliance with France's Renault and Mitsubishi Motors, Nissan said it was not the time to discuss revising the partners' capital ties. Ghosn, who spearheaded Nissan's turnaround two decades ago, had pushed for a deeper tie-up between Nissan and Renault, including possibly a full merger by 2020, despite strong reservations at the Japanese firm. "We are not at the stage for such discussions," Nissan CEO Hiroto Saikawa told reporters on Monday. Saikawa said he had not heard directly about a reported proposal by the French government to integrate the Japanese carmaker's management with Renault. The Nikkei newspaper reported on Sunday that a French government delegation had informed Tokyo that it would seek an integration of Renault and Nissan, most likely under the umbrella of a single holding company. "Since I have not heard this directly, I cannot comment," Saikawa told reporters.

Full 2015 Chevy City Express details revealed

If you're thinking, "hey, that looks familiar..." you aren't alone. We've already seen photos of the 2015 Chevrolet City Express van. And before that, we've already learned everything there is to know about the Nissan NV200 upon which its quite obviously based. Now, though, the City Express is holding its official coming out party at the Chicago Auto Show, and we finally have the official details about what'll hopefully make this van attractive to work-minded buyers.
To no one's surprise, the City Express doesn't offer any mechanical differentiation from its Nissan equivalent. Power comes from a 2.0-liter inline four-cylinder engine rated at 131 horsepower and 139 pound-feet of torque, mated exclusively to a continuously variable transmission. Of course, the purpose of the City Express is less about what's under its hood and more about what it can haul in its capacious cargo area. Chevrolet says the front passenger seat can fold flat to create a work space or accommodate longer objects in the cargo bay, there's a center console designed specifically for maximum storage capability and both sides of the van have sliding doors. In addition, there are a plethora of integrated cargo mounts, floor-mounted D-rings and roof rack mounts throughout the vehicle.
Visually, Nissan's NV200 has never exactly been a handsome thing to begin with, and this City Express doesn't really tweak it for the better - to our eyes, it might even be less attractive. Even the design of the 15-inch wheel covers have been left alone, though the Chevy shown here appears to wear chrome-finished units.
