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.

Porsche 911 and Nissan 350Z get smoked by unlikely hero

So a Nissan 350Z Procharger and a current Porsche 911 GT3 drive onto the Autobahn together - stop me if you've heard this one before - and they decide to race. We're not sure how much power the Z is packing, but the stock model topped out at 306 horsepower on the last year of its run in 2009. And if that's a stock GT3 then it will be rocking something like 475 horsepower. So the Z and the GT3 give it a racing go, and just as one of them starts to pull away they're both overtaken by one of the most unlikely dark horses you could imagine. It's a really short video and we won't spoil the surprise, so check it out above.

Watch a Nissan GT-R run Le Mans in 360-degree video

If you aren't reading this post on your iOS or Android device, or in the Chrome web browser, you're going to want to switch formats. That's because the video above is shot in an interactive, 360-degree format, and it only works on the YouTube app or in Chrome. Got that sorted? Good. What you see here is a Nissan GT-R running a full lap around the Circuit de la Sarthe, better known as the location for the annual 24 Hours of Le Mans. And since this year's race takes place this weekend, there's no better time to get a beautiful, interactive look at the road course from literally every angle. The video is super cool, and trust us, you'll want to get the full 360-degree experience. We found it worked best when viewed on an iPhone or Android, because as you move the entire phone with your hand, that controls the camera's movements.
