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.

Scion iA and iM rolled into Yaris and Corolla lineups for 2017

The Scion brand may be going away, but most of its cars (sorry, tC) are living on. We'll see the 2017 Toyota 86 (nee Scion FR-S) at the New York Auto Show next week, and the automaker already confirmed that the Scion iA and iM will be rebadged as Toyotas. But instead of standing on their own, the former Scions will be rolled into existing model lines. "Yaris iA" and "Corolla iM" will be the official names of the cars, effective for 2017. It's a smart move, paring the relatively new Scion nameplates with well-known, existing Toyota monikers. Scion spokeswoman Nancy Hubbell tells Autoblog that the iA already exists as the Yaris in the Canadian and Mexican markets, so "that connection was already there." Plus, it's better for marketing. The combination of the two vehicles all under the Yaris nameplate means Toyota can focus its advertising dollars on one vehicle line, simply saying that you can now have the Yaris as a four-door sedan or a five-door hatchback. "The same goes with Corolla," Hubbell explains. She says the existing Toyota sedan and the Scion iM "paired really well," and again, it means Toyota can advertise the Corolla as having two body styles moving forward. There are benefits from a sales perspective, too. Never mind that Scion division sales were already included in Toyota's overall numbers – calling the new cars Yaris iA and Corolla iM means the company won't have to report these cars individual sales separately. It's like when Toyota made the Matrix – its technical name was Corolla Matrix, so its individual sales didn't have to be broken out. That means an extra boost in overall numbers for the Yaris and Corolla, even if the cars would have been reported under Toyota's numbers had they kept their Scion badges.

Toyota 86 most likely to get more power through more displacement? [w/poll]

The Sydney Morning Herald has spoken to Tetsuya Tada, chief engineer of the Toyota 86 (our version of it, the Scion FR-S, is pictured above), and they've been promised that more power is on the way. We've heard a lot of speculation about a more powerful Toyobaru since before the standard model was even launched. The only question now is how the power will be delivered, and among the engine concepts we've already heard about - turbo, supercharger, twin-charged, hybrid - is a new one: more displacement.
Tada said that an engine with more displacement than the current coupe's 2.0 liters is being tested alongside a turbocharged and a hybrid-assisted motor. The SMH cites "inside sources" as saying the displacement option is the one likely to get the go-ahead, and suggests increased bore and stroke will see the engine grow to 2.5 liters, horsepower to about 250 - a 50-hp increase over the present car.
While that's apparently the betting man's solution for the long-awaited increase in gumption, what happens with the next generation could be more wide open than we suspected. According to the report, Tada "hinted that [a successor] could be a radically different car, potentially dropping the boxer engine altogether." He said once they've sorted out the concept for the second generation car, then they'll sort out an engine. That's where a turbo option could come to market, perhaps the turbocharged four-cylinder Toyota is developing for the Lexus NX crossover or a hybrid system that uses a capacitor.
