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 and Renault chief engineers meeting to revive joint projects

PARIS — Renault's engineering boss will meet his counterpart at Nissan in Japan this week, two sources close to Renault said, as the carmakers seek to revive projects crucial to an alliance left reeling by the Carlos Ghosn affair. The Franco-Japanese alliance is wrestling with the fallout of the ouster and arrest of Ghosn, the architect of the partnership who now says it is at risk of collapse. Analysts say that in order to turn investor sentiment around, the firms need to make good on cost-saving joint engineering projects that have slowed since Ghosn's departure. According to the two sources, Gilles Le Borgne, who was hired on Jan. 6 from rival automaker PSA, will meet Nissan's Tsuyoshi Yamaguchi, the Nissan executive in charge of delivering the joint engineering projects. Renault did not respond to a request for comment on Le Borgne's meetings. Renault-Nissan's cost-saving alliance is vital to both companies as the car industry battles a slowdown and huge investments in cleaner vehicles and automated driving. "The alliance has taken a hit, but the alliance engineering team is still there," said a third source, who is close to the alliance. "You cannot, from one day to the next, stop something that's been embedded so deeply." Japanese prosecutors arrested Ghosn — who was at the time the head of the carmakers' alliance -- in November 2018 and accused him of financial misconduct. Ghosn slipped out of Japan and fled at the end of December to Lebanon. He says the charges were fabricated to force him out of an alliance in which the Japanese side no longer trusted its French partners. Renault Chairman Jean-Dominique Senard has said both sides are determined to make the partnership succeed, with the joint projects a major focus. Those projects will be on the agenda when the board of the alliance, which also includes Japanese carmaker Mitsubishi <7211.T>, holds a regular meeting in Japan on Jan. 30. One area of focus will be hybrid power systems, a field where, analysts say, the alliance has not effectively pooled its research and development efforts. Each of the three members of the alliance has developed their own systems. "That's been among the sources of the friction," said the third source close to the alliance.

Nissan BladeGlider Concept shows its inner DeltaWing

Just like the DeltaWing and ZEOD RC racecars, it takes seeing the Nissan BladeGlider concept live to get a true appreciation for its design. But that doesn't mean it's any less weird. The wedge-shaped, three-seat concept car hit the stage today at the Tokyo Motor Show, and Nissan says the car is an "exploratory prototype" for a future production model.
The BladeGlider is defined by its design with front wheels that are just about three feet apart, while the rear has a more conventional track. Opening the scissor doors reveals a center driving position flanked by two passenger seats with a cockpit-inspired design. Although no power figures were revealed for the conceptual vehicle, Nissan does say that the BladeGlider is an all-electric vehicle with its battery pack mounted toward the rear of the car helping to provide a 30/70 weight distribution front to rear.
