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.

Is a Nissan Leaf with a 250-mile range less than three years off?

Nissan CEO Carlos Ghosn has never shied away from bold proclamations. Most recently, he implied that an electric vehicle with a single-charge range comparable to that of a gas-powered vehicle on a full tank may be fewer than three years out. We'd love to see it. Indeed, Ghosn said that such a car may be around in the "near future," Hybrid Cars said, citing a presentation Nissan CEO Carlos Ghosn made to shareholders earlier this week. He also showed a video of a Nissan Leaf in Japan, which appears to start out on a trip with 417 km (259 miles) of range available. The 2015 Leaf's single-charge range is rated at 84 miles in the US. How to get another 120 miles or so? Ghosn's talking about a still-lighter vehicle as well as cheaper batteries and improved battery chemistry. He also alluded to shorter recharging times. Last month, word got out that Nissan was working on a top-of-the-line Leaf that, as soon as this fall, would include a 30-kilowatt-hour battery, up from the standard 24-kWh version. Such a variant, which would be launched ahead of the next-generation Leaf slated for as soon as 2017, could boost the Leaf's single-charge range to as far as 105 miles.

Renault-Nissan alliance reboot will kick off with five projects

Renault SA and Nissan Motor Co. are moving ahead with a plan to recalibrate a two-decades-old alliance that had weakened over time, starting with a range of industrial projects alongside an agreement to rebalance capital ties, according to people familiar with the situation. Top executives from the alliance partners held an operating board meeting on Thursday, giving a nod to bringing Nissan and Renault’s cross shareholdings to an equal level, as well as common projects as part of the reshaped cooperation, the people said. The partners also agreed on an alliance event to be held on Feb. 6 in London to present details of the plans, the people added, declining to be named discussing details before they are public. Under the landmark plan, Renault is expected to cut its 43% stake in Nissan to 15% via an orderly disposal of shares over time to eliminate lopsided capital ties that have been a source of friction for years. The tentative agreement comes after years of tension that at one point spilled over into Japanese-French politics when Renault-NissanÂ’s then-leader Carlos Ghosn weighed to merge the two companies.   The partners also agreed to continue collaborating on various industrial projects, a condition that was crucial for Renault to obtain approval for the rebalancing from its most powerful shareholder, the French government. Media representatives for Renault and Nissan declined to comment. The boards of directors of the respective companies will have to approve the agreement in meetings to be held in coming days, the people said.  Code name: ‘ReloadedÂ’ The redesigned alliance will allow Chief Executive Officer Luca de Meo to move on with a complex split of Renault into five separate businesses, including carved-out electric-vehicle business Ampere and to deepen ties with a series of other partners, including ChinaÂ’s Zhejiang Geely Holding Co. and Qualcomm Inc., the people said. “The interest for each of the partners is now to be able to move forward without, for example, RenaultÂ’s management getting distracted in endless trans-national politics,” says Stifel analyst Pierre-Yves Quemener. Failure of the talks would have been “a negative,” Quemener said.  Renault, Nissan and junior partner Mitsubishi Motors Corp. will embark on roughly five projects initially, codenamed “Reloaded,” with others to follow, the people said.
