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.

Toyota FT-86 Open Concept leaves us feeling flushed

When last we checked in on our topless would-be hero, the Toyota FT-86 convertible had been reportedly placed on "indefinite hold." That was back in early October, not long after Toyota had trotted out the rear-wheel-drive canvasback to Scion dealers as a possible future product carrot if they decided not to turn in their franchises. And yet, we're here at the Tokyo Motor Show, where Toyota has taken the time to at least repaint the FT-86 Open Concept in "Flash Red," if not build a whole other car (the original Geneva showcar was white). It's enough to make our heads spin like a teenager on the verge of a breakup. Will they? Won't they?
At this point, we still don't know any more than you do - the last word we heard out of Toyota was not encouraging, although the story was that the program could still be fast-tracked if management had a change of heart. As the car has never been seen before in Japan, perhaps Toyota is merely extending its domestic audience a courtesy view before it lines this showcar in mothballs, or maybe they're still trying to make a decision on its fate and gauging public reaction on the homefront.
Interestingly, in a new story published today, Automotive News quotes Subaru brand boss Yasuyuki Yoshinaga downplaying the likelihood of a production model, saying flatly "We make the car, so if we don't make it, it can't happen." The executive went on to note, "Our engineering department told me that losing the entire roof requires a complete redesign of the structure. It would need a big change." Given that such a car would probably trade in rather small volumes, that sounds like a significant hurtle.

Coming Toyota Supra to forgo hybrid, get a BMW six-cylinder turbo?

For years, almost all of the talk about the Toyota FT-1 concept becoming a resurrected Supra envisioned a hybrid under the hood. And then the latest take on Future Toyota 1 showed up at the 2014 Detroit Auto Show and - although Toyota wouldn't say a word about any engine at all - horizons began to expand. Imaginary fancies were aided by the news that Toyota had partnered with BMW to develop a sports car on the next-generation BMW Z4 platform, which would necessarily mean an engine bay designed to accept an old-fashioned hunk of gas-burning iron-working solo. Car and Driver now turns the whole thing around, reporting that there will be an inline-six with forced induction provided by BMW under the hood. What about that hybrid, though? The report states, "there's currently no indication that the Silk Road cars will offer hybrid options" - 'Silk Road' being the codename for the jointly-developed vehicles. CD makes a point to note that said tidbit came from Germany, not Japan. However, designers at Toyota's Calty studio did tell Automotive News last year that they designed the body with an inline-six in mind, a nod to the Supra's history. Hybrid rumors aren't dead yet, though - remember, we were hearing about all-wheel drive and supercapacitors in May 2014. The coupe is predicted to be a 2018 model, making its appearance sometime in 2017, and be "about 10 percent" smaller than the FT-1 concept. Related Video:
