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.

Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way. The politician in question is State Assemblyman Tim Eustace (D-Bergen), who was purposefully hit by a blast of dark smoke recently while driving his Leaf on the New Jersey Turnpike, according to NJ.com. This personal experience of what he called "just youthful ignorance" is encouraging him to submit a bill (A3583), which, "Prohibits retrofitting diesel-powered vehicles to increase particulate emissions for the purpose of 'coal rolling'; prohibits the practice of 'coal rolling.'" If you're caught violating the law, you would be hit with a fine from the state Department of Environmental Protection. Of course, the Feds say it is already illegal to modify an exhaust system in a way that allows coal rolling. Rolling coal has become a bit of a meme recently, with videos of laughing truck drivers spewing their modified exhaust pipes at green cars, pedestrians and bikers around the country. Eustace told NJ.com that, "People had been telling this has been going on, but I hadn't seen it. I was surprised to experience it myself." Perhaps a coal roller in New Jersey will be surprised, too, when the first big fine hits. News Source: NJ.comImage Credit: YouTube Green Nissan Green Culture Diesel Vehicles rolling coal

Bug-eyed next-gen Nissan Titan spied testing

It's no secret that the fullsize pickup truck market is dominated by offerings from Detroit's Big Three automakers, the Nissan Titan and Toyota Tundra not able to outdo the Ford F-150, Ram 1500 or Chevy Silverado/GMC Sierra twins. A great deal of that has to do with the fact that, while the American trucks have all undergone evolutionary updates that include a range of body styles, fuel-efficient engines and excellent technology, the Japanese offerings are, well, really old. Toyota is offering an updated Tundra for the 2014 model year, and while we haven't driven it yet, we're already betting that it's still behind the pack in terms of competitiveness - the 2013 model placed fifth out of sixth in a recent PickupTrucks.com comparison test.
At the bottom of the pack lies the Nissan Titan, a truck that hasn't received any sort of substantial update since its introduction nearly ten years ago. But that's going to change - a new truck is slated to debut for the 2015 model year, and these spy shots of a Titan mule clearly show that things are moving forward.
While this tester relies heavily on the current truck's bodywork for testing purposes, the new Titan will have a revised design, some of which is evidenced by the bug-eyed front fascia of this mule. No, the production model isn't going to look all weird (we hope), but the higher, more outboard headlight placement suggests that the new truck will be a bit wider than the current model.
