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.

Deltawing takes out second ad targeting Nissan amidst design lawsuit

Don Panoz isn't a guy shy away from a fight. Since December, Panoz's Deltawing Technologies has been in a lawsuit with Nissan over alleged intellectual property violations with the design of the Zeod RC. The situation went public several weeks ago when Deltawing bought an ad in The Tennessean, a paper near Nissan's US headquarters, and the industry trade, Automotive News, aimed squarely at company CEO Carlos Ghosn.
Now, Deltawing is trying the tactic a second time with an even more scathing ad in The Tennessean on July 11 and in Automotive News on July 14 that calls the Zeod's design out directly. The bulletin puts the two racecars side by side and asks readers compare their similarities.
According to Deltawing spokesperson Gary Fong, the idea for these ads started after mediation between the company and Nissan broke down earlier this year. "We were trying to bring them to settle it amicably," he said to Autoblog. When that didn't happen, Deltawing wanted to fight the misconceptions in the public about the program and lawsuit. The strategy actually worked, too. "We've seen an opinion change," said Fong. He estimates that before the advertisements the attitude was "90 percent against Panoz," but there has been more support since them.

Renault chairman dismisses reports Nissan wants to split from alliance

PARIS — Renault Chairman Jean-Dominique Senard said on Thursday there was a "real desire" within the top ranks of both companies for its alliance with Nissan to succeed, dismissing suggestions the partnership was on the rocks. Turmoil within the Franco-Japanese alliance, long dogged by internal rivalries, deepened following the November 2018 arrest in Tokyo of its architect and long-time boss Carlos Ghosn on charges of financial crimes, which he denies. Attempts to restore calm were dealt a fresh blow by Ghosn's dramatic flight from Japanese justice and a series of no-holds-barred allegations he has made from his refuge in Lebanon, including that he was the victim of a plot to oust him and that the alliance is now a "masquerade". Nissan has vigorously rejected Ghosn's stance, while both the Japanese firm and Renault have tried to rubbish suggestions their two decades old partnership is falling apart. "We have a board overseeing the alliance which is made up of people who are all extremely in favor of the alliance," Renault Chairman Senard told a briefing with reporters. "There is a common desire to associate our strategic plans and a real desire to make this alliance a success," he added, dismissing a report that Nissan was examining scenarios for a possible future outside of the alliance as "fake news." The 66-year-old declined to comment on anything related to Ghosn, adding: "I only think about the future." Renault shares were down 2% by 1123 GMT, underperfoming the broader auto sector which was down on news that Washington has threatened to impose tariffs on European car imports due to Europe's stance on Iran. Renault's French rival and Peugeot maker PSA Group also gave a flavor of some industry headwinds, reporting a 10% fall in its global sales last year as Chinese demand tanked. Renault is due to publish its 2019 global sales on Friday. JOINT PROJECTS Analysts see Renault-Nissan's cost-saving alliance as vital to both companies as the car industry battles a slowdown and huge investments in cleaner vehicles and automated driving, particularly as rivals PSA and Fiat Chrysler are merging to help meet these challenges. Renault held ultimately unsuccessful talks to combine with Fiat Chrysler last year, which Ghosn described at a Beirut news conference as a huge missed opportunity. Senard, who chairs the alliance's operating board, said on Thursday that once the partnership has been rebooted, other firms might potentially want to join.
