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 unofficially teases TE-S800 plug-in hybrid roadster

We really want to party with the Toyota Engineering Society. With the mothership company showing a bunch of modifications at the Tokyo Auto Salon last month, that nutty engineering group used the event to unofficially show off its TE-S800 PHEV roadster, as you can see in the two-minute video below. The car is a plug-in hybrid that pairs the 115-horsepower gas engine that's standard issue on the Toyota Prius hybrid with a 102-horsepower electric motor. The right-hand-drive two-seat-vehicle also sits on the platform of the little-bitty MR2 (remember those?) so it weighs in at less than 2,000 lbs. And, as you can see, the car's also painted bright green (now there's a hint) and kind of cool-looking. Do the math of combining more than 200 horsepower with a featherweight car, and you've got a rather sporty vehicle that can sprint from 0 to 60 miles per hour in less than six seconds, all while getting outstanding fuel economy. Yippee! Engineering Society aside, the Japanese automaker brought more than 30 customized vehicles to the Salon. Those included the Harrier G Sports Concept, a modified version of the Toyota's new crossover, and the Vitz RS G Sports Concept, which is a sported-out Yaris. This content is hosted by a third party.

Details about next-gen Toyota Prius emerge

The Toyota Prius is undeniably the king of the hybrid market in the United States, with a 39.4 percent market share in 2013. With the next-generation Prius likely to go on sale in 2015, Toyota is trying to build an even more efficient hybrid to keep its control of the market.
Keeping cost down will be one of the major concerns of the new Prius. The next generation will ride on the new, modular Toyota New Global Architecture platform. The lighter underpinnings will improve efficiency and will reduce production costs by allowing for more shared components among vehicles. Toyota will not reveal how many vehicles will use the new platform. But even with the cheaper platform, price will remain a concern. Toyota is still deciding whether all versions of the next Prius will use lithium-ion batteries or whether some models will stick with the heavier nickel-metal hydride batteries to keep cost down.
Of course, the reason most people buy the Prius is because of its great fuel efficiency. Toyota will aim for at least an 8 percent improvement in fuel economy in the next Prius, which would increase it to 58 miles per gallon city and 52 mpg highway.
