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.

Recharge Wrap-up: Model X pinch sensor update, Karma plans first store

Tesla has improved Model X pinch sensor function in its latest over-the-air update. As we've seen, the pinch sensors already stop the falcon wing doors from completely shutting when they sense an obstruction. Now, though, the doors retract slightly after the sensors are triggered. While the pre-update doors didn't appear to do as much damage to human fingers as they do to various foodstuffs, it definitely looked uncomfortable, especially when one's hand is stuck in the partially closed door. Now, any pinch that does occur should be brief. See the updated sensors at work in the video above, and read more from Teslarati. Karma Automotive will move to Kawasaki's former headquarters in Irvine, California where it will also open its first store. The revival of the now defunct Fisker will sell its Revero plug-in hybrid through both dealerships and company-owned stores like the one planned for its new two-building campus. The property owner, Bixby, had planned to renovate the site, but now says Karma will make its own improvements. Bixby said it was seeking, "a progressive-minded tenant that would value the unique configuration," and appears to have found just that in Karma. Read more at Electrek, or from the OC Register. San Francisco is asking residents for help in expanding its subways. Using an online tool called Subway Vision, users can draw their own subway lines and stations that they'd like to see built and submit them to planners. Listening to the public is a useful tool for the city because, as Grahm Satterwhite, San Francisco Municipal Transportation Agency's principal planner, admits, "Transportation planners may be too close to a problem to see the solution." This approach allows the subway expansions to "reflect the vision of not just a few transportation planners, but of all San Franciscans," he says. Read more from FastCo.Exist. Toyota is continuing its commitment to Yellowstone National Park with a sustainable Youth Campus for environmental education. The automaker donated $1 million to Yellowstone for the facility, which is seeking Living Building Challenge certification. It will have onsite wastewater treatment for its locally sourced water usage, and will generate all of its electricity needs from photovoltaic panels, with excess to put back into the grid. The campus will have classrooms and residences for students and staff for its youth programs.

Toyota i-Road is no less strange in the flesh

We've seen plenty of three-wheeled creations in our day, but none quite like the Toyota i-Road Concept. The "personal mobility vehicle" offers seating for two with driver and passenger positioned in a tandem position. While that may sound more like a motorcycle than a car, the closed cockpit means riders don't need a helmet. The design also takes a page from the 2008 Peugeot HyMotion3 Concept with an articulating front suspension that allows the driver to lean through corners thanks to "Active Lean" self-balancing technology. Unlike the funky Pug, however, the i-Road is a fully electric plug-in vehicle.
While there are just five-horsepower on hand from an electric motor, the i-Road should serve up a range of around 30 miles thanks to its lithium-ion battery, and Toyota claims the cells can be topped off in three hours with a "conventional domestic power supply." Sounds majestic. Take in the full press release below.
