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 unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Recharge Wrap-up: Japan supports hydrogen, Fools against fuel cells, BlueIndy controversy

Japan hopes to expand the use of hydrogen energy by subsidizing fuel cell vehicles, according to The Japan News. The trade ministry plans to include the subsidies in its 2015 budget to coincide with the expected launch of Toyota's Fuel Cell Vehicle and the Honda FCEV hydrogen car. By jump-starting purchases of hydrogen cars, Japan hopes that innovation and mass-production will get a boost and the cost of fuel cell vehicles will be competitive with gasoline-powered models by the year 2025. Japan plans to have 100 hydrogen fueling locations operating by March 2016, and wants to halve the cost of building those stations by 2020. The amount of the subsidies has not yet been set. Investing website The Motley Fool isn't quite as optimistic as Japan about hydrogen cars, and is instead bullish about Tesla Motors. The Fool points to Tesla's strong stock performance, and predicts future growth will come from more car models in the future - starting with the Model X - as well as the company's proposed Gigafactory for manufacturing batteries. If Tesla's charging technology continues to catch on, that only improves its financial prospects. The article has some harsh words, however, for hydrogen: "Fuel cells are an inferior automotive technology and for fundamental efficiency, cost, and infrastructure reasons always will be mere compliance gimmicks." Yeesh. As part of a program to build charging stations for the Indianapolis EV carsharing service BlueIndy, utility company Indianapolis Power & Light (IPL) wants to raise its electricity rates an average of 44 cents a month per residential customer to help pay for its share of the project. State consumer advocacy agency Indiana Office of Utility Consumer Counselor and consumer watchdog group Citizens Action Coalition oppose the plan, according to Greenfield, Indiana's Daily Reporter. The BlueIndy program, which is a partnership between the city of Indianapolis and battery manufacturer Bollore Group, will provide up to 500 cars for rent at 25 charging sites around the city. Those who oppose the rate hike call IPL a monopoly and say the amount of the increase is not allowed under state law and that the program wouldn't benefit working class and low-income citizens. A hearing regarding IPL's proposal is scheduled for July 23. A Mitsubishi Outlander PHEV will run the 2014 Asia Cross Country Rally, Hybrid Cars reports. The rally covers 1,367 miles of woods, swamps and mountains from Thailand to Cambodia.
