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.

2016 Mazda MX-5 Miata has arrived

Ladies and gentlemen, meet the 2016 Mazda MX-5 Miata. The highly anticipated fourth-generation (ND) model made its official debut in Monterey, CA this evening, and while details are slim (as in, we have practically none), there's one big thing to talk about: less weight.
Yes, Mazda has confirmed that the new Miata sheds some 220 pounds over the model it replaces, and is "the most compact of any generation MX-5 so far." For those keeping track, that means the new MX-5 should weigh in somewhere around 2,200 pounds.
Mazda's Kodo design language is obvious here, with a seriously wide and low demeanor, and a mix of flowing lines and sharp angles. We don't have any powertrain details to report as of this writing, but Mazda says the full suite of Skyactiv technologies are onboard, and the motto in creating this car was "Innovate in order to preserve."

Evo pits Toyota GT86 vs. Mazda MX-5 Miata

The latest Deadly Rivals episode from Evo gets the Mazda MX-5 Miata and Toyota GT86 (our Scion FR-S) on track for a shakedown and a whole lot of drifting with Dan Prosser behind the wheel. The UK-spec coupes have slightly different power ratings than ours, but it's all close enough to be comparable. Their Miata has 158 horsepower (ours has 155), 148 pound-feet of torque, takes 7.3 seconds to run from naught to 60 62, and costs 22,695 pounds. The GT86, on the other hand, lists a 7.6-second dash to 60 62, and a base price of 25,000 pounds. The GT86 also weighs 400 pounds more than the Mazda. That's true in the States, too – curb weight for our MX-5 is 2,332 pounds, whereas the Scion FR-S comes in at 2,758 pounds. Both cars lauded for excellent shifting, but one of them has a better front end, a sweeter engine note, more controllable cornering behavior, and is faster by a tenth of a second around the test track. And Prosser doesn't mention it, but one has a lot more body roll. But it takes more than all that to make a winner, so check out the video above to see which is which.
