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.

Investigators say Mitsubishi mpg scandal was 'collective failure'

Investigators hired by Mitsubishi Motors to probe why the Japanese automaker engaged in falsifying fuel-economy figures for the past quarter-century faulted the company's "corporate culture." Specifically, there was a lack of unity between divisions, company-wide pressure to boost fuel-efficiency numbers, and an unwillingness to accept fuel-economy shortfalls, Automotive News says, citing comments made by consultants who hired by the company to investigate the problems. Challenging management authority even if it was proper to do so was also frowned upon. One of the investigators called the scandal "a collective failure." Among other suggestions, the consultants recommended that Mitsubishi's vehicle-mileage certification be independent from research and development, that there's greater transparency overall, and that there's a more thorough understanding of laws. New shareholder Nissan may also invest in retooling Mitsubishi's R&D operations, and is sending one of its former executives, Mitsuhiko Yamashita, to Mitsubishi to try to prevent any sort of repeat problems. Mitsubishi joined a list of automakers including Volkswagen, Hyundai/Kia, and Ford that have been found in recent years to either mislead with its published fuel-efficiency figures or emissions-testing procedures. A Nissan spokesman declined to comment on the Mitsubishi report, according to Automotive News. The recommendation comes less than three months after the announcement that Nissan would help rescue Mitsubishi from its fuel-economy scandal by acquiring part of the company. Nissan agreed in May to pay $2.2 billion for a 34-percent stake in Mitsubishi, and said at the time that Mitsubishi would join the Renault-Nissan Alliance. Nissan also owns 15 percent of France-based Renault. That announcement came right after Mitsubishi's admission that it may have falsified fuel-economy data for every one of its vehicles made in Japan dating back to 1991.

Formula Drift kicks off 11th season on Streets of Long Beach

The 2014 Formula Drift series kicked off last weekend in Long Beach, and saw Chris Forsberg, who you'll recall went mad and drifted around a warehouse in an Infiniti M, take the title behind the wheel of his Hankook Tire Nissan 370Z (shown above).
Forsberg really ran away with the first round of competition, outscoring his closest opponent, second-place finisher Kenneth Moen and his Bridges Racing Nissan 240SX, by 20 points. Third place was 2013 championship winner Michael Essa and his Yokohama BMW M3, 30.5 points behind Forsberg.
In the manufacturers' title, Nissan took an early lead with 122 points, which isn't a huge surprise considering five of the top ten drifters were piloting either a Z or a product of the brand's S platform. Ford, which had two drivers (Justin Pawlak and Vaughn Gittin, Jr.) in the top ten, took home second place, while BMW is currently third in the manufacturers' standings.
