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 close to licensing deal with BMW for fuel cell technology

For over a year now, we've been hearing about a potential partnership between Toyota and BMW on everything from sports cars to lithium-ion batteries, but one of the first cooperative projects between these two automakers could bring Toyota's hydrogen fuel cell technology to a BMW vehicle. Reuters is reporting that an announcement is likely to be made as soon as later this week regarding a BMW fuel cell vehicle that could be in production by 2020 with a prototype running around by 2015.
The last we heard of Toyota's fuel cell technology, it was in the FCV-R Concept that we saw at the 2011 Tokyo Motor Show, but there is no word how far along in development this system is. If it does come to fruition, such a vehicle for BMW would build on the automaker's commitment to hydrogen that started with the Hydrogen 7, which unlike a fuel cell vehicle, simply ran on hydrogen fuel rather than converting it to electricity for use in motors. We're definitely interested where this Toyota/BMW tie up could be headed.

Toyota Prius remains best-selling vehicle in California, wireless charging tests underway

About one in every nine new cars in the US are sold in the California. If we're just looking at the four Toyota Prius hybrid variants, then the number becomes closer to one in three. Tesla Model S battery-electric vehicle sales? Try one in 2.7. For the second straight year, the Prius was the best-selling car in the Golden State. Toyota sold 69,728 Priuses there, almost a third of the more than 234,000 sold in the US in 2013. Prius sales in California alone were up almost 13 percent. And Toyota's ready to build upon that momentum with a new version of the Prius Plug-in Hybrid, saying that it's testing a wireless recharging system in Japan's Aichi Prefecture and will start similar tirals stateside later this year. We'll make the wild prediction that some of those tests, which involves magnetic resonance, will be in California. Meanwhile, Tesla's numbers were, in their own way, were more impressive. The California-based automaker sold 8,347 of its Model S units in the Golden State out of about 22,300 nationwide in 2012, Bloomberg News reports. In all, advanced-powertrain vehicles accounted for 9.3 percent of California new-vehicle sales, compared to 3.8 percent for the country, Bloomberg says, citing Hybrid Cars and Baum & Associates. Check out Toyota's press release on its California sales below. Prius Medals In The Golden State Toyota Prius is best-selling vehicle line in California Wireless charging testing for Prius Plug-in TORRANCE, Calif., Feb. 18, 2014 /PRNewswire/ -- The Prius took home the gold in 2013 as the most popular vehicle-line in California for the second year in a row. The Prius Family (Prius Liftback, Prius v, Prius c and Prius Plug-in) took the podium in both 2012 and 2013 as the best-selling California vehicle name plate. 69,728 drivers hit the road in 2013, according to the California Auto Outlook Report, while 61,893 Californians joined the family in 2012. In the Golden State, the Prius Family outsells all other hybrid competitors combined. California drivers lead the country in adoption of vehicles powered, either wholly or partially, by electricity. 9.3% of vehicles sold in the state run on some form of electricity, according to the report. But despite the growing number of hybrid competitors, Toyota's hybrid leadership remains unmatched. In fact, one out of every two hybrids in California carries the Prius name plate.
