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.

Watch this time-lapse build of the Chevy SS for NASCAR

There's only about a week left until we get our first look at the production version of the 2014 Chevrolet SS sedan, but Chevrolet NASCAR teams have been looking at the race version of the car all winter. Autoweek has posted a really neat time-lapse video showing just a portion of what it takes to build one of NASCAR's new Gen6 stock cars.
Though the video is quite brief, it does show almost the entire build process starting with just the car's nose, and it gives us a good look at how integral the template is to the final product. As a bonus, Hendrick Motorsports also provided some videos showing two of its teams performing pit stop tests over the winter. The second video shows some of the more detailed aspects of the racecar's rear end, including the stock-looking trunk cutout and a newly mandated rear bumper extension that will be used on super speedways like Daytona and Talladega.
To see what Team Chevy has been up to all off-season, check out all three videos posted after the jump.

LG Chem ready to double workforce at plant that makes Volt batteries

With a history that involves paying people not to work, the fact that LG Chem is going to hire more people for its electric-vehicle battery plant in Holland, Michigan is good news on a couple fronts for the Korean company. The South Korea-based LG Chem is holding a job fair at the factory about 30 miles west of Grand Rapids. The company wants to double its workforce this year to "several hundred people." LG Chem, whose factory notably makes the cells for General Motors' Chevrolet Volt extended-range electric vehicle battery, is looking for everything from technical operators to maintenance workers to production supervisors. The company held a previous job fair last September that resulted in about 40 people being hired. The prior year, though, LG Chem gained a measure of infamy after the US Department of Energy (DOE) discovered that workers were, for a time, getting paid to do absolutely nothing because low demand for battery packs made it cheaper for the factory to remain idle. With LG Chem also making electric-vehicle battery components for Ford, Renault, Hyundai, and Volvo, though, those lazy days appear to be long gone. Take a look at LG Chem's press release below. Show full PR text LG Chem Michigan Inc. 2nd Job Fair Will Help To Double Its Holland Workforce HOLLAND, Mich., May 13, 2015 /PRNewswire/ -- LG Chem Michigan Inc. (LGCMI) is conducting a 2nd job fair on Thursday, May 14 as part of the company's efforts to double the size of its production workforce in 2015.
