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.

Mazda starts production of new MX-5 Miata in Japan

We often regard a new model as having arrived when its manufacturer reveals it for the first time. But you might argue that nothing is official until actual production gets underway. And that's just what's happened now with the new Mazda MX-5. The fourth-generation Miata was unveiled a few months ago, and now the first examples have begun to roll off the assembly line at Mazda's Ujina plant in Hiroshima. The first ones are set to stay in Japan, where the new roadster is being introduced initially. Deliveries are set to launch in June. After that, we can expect the new MX-5 to proliferate to markets around the world, including our own. To date Mazda has sold more than 950,000 of its little roadsters, making it the best-selling two-seat sports car in the world. It shouldn't be long, then, before the new model tips it past the million-unit mark. 2015/03/05 Mazda Starts Production of All-new Mazda MX-5 HIROSHIMA, Japan-Mazda Motor Corporation today began production of the all-new Mazda MX-5 two-seater lightweight sports car (known as Mazda Roadster in Japan) at Ujina Plant No.1 in Hiroshima. The first models produced are destined for the Japanese market. Sales of the all-new MX-5 will begin in Japan around June this year and interested buyers can make an appointment for pre-sale discussions through a dedicated website from noon on Friday, March 20. Following sales start in Japan, the MX-5 will be progressively rolled out to overseas markets. The MX-5 is an iconic model representing Mazda's vehicle engineering philosophy: the pursuit of driving pleasure. With production exceeding 950,000 units as of the end of January 2015, the MX-5 continues to hold the Guinness World Record for the world's best-selling two-seater sports car. In order to respond to ever increasing demands for safety features and environmental performance while maintaining the element of fun that has always defined the model, development of the fourth generation MX-5 was carried out under the motto "innovate in order to preserve". In addition to incorporating SKYACTIV TECHNOLOGY and KODO-Soul of Motion design, development focused on enhancing the senses and sensations through which people enjoy cars. Moving forward, Mazda will continue to enrich the lives of its customers through a variety of touch points including the production of high-quality vehicles, and become a brand that maintains a special bond with its customers.

2016 Mazda MX-5 Miata priced from $24,915

When Ford introduced the 2015 Mustang, it gave us 300 percent more car for about 10 percent more money. Mazda has done even better with the MX-5 Miata: the current roadster starts at $23,970 in Sport trim with a five-speed manual, the smaller, lighter, sharper 2016 model is just under $1,000 more, starting at $24,915 with a six-speed manual. Destination, unchanged, adds $820 to that MSRP. It is divided into the same three tiers of Sport, Club, and Grand Touring but the standard feature set grows, with the departure of that five-speed manual for six-speeders across the board, LED headlights, and extra infotainment functionality. Mazda says it will release more pricing in the future, but so far things just keep looking up for the one of the best little roadsters out there. The press release below has more.

(March 30, 2015) – Mazda North American Operations (MNAO) today announced that the 2016 Mazda MX-5 Miata will start at $24,9151 in entry-level Sport trim. Mazda has instilled the latest MX-5 with the pure driving experience that has won worldwide fanfare since the arrival of the first-generation MX-5 in 1989 as a 1990 model. Yet, the fourth-generation MX-5 provides Mazda's latest safety features and technologies and maintains an inflation-adjusted price close to that of the original roadster. The 2016 MX-5 launches this summer and will be available in Sport, Club and Grand Touring trim levels. "As we get closer to the MX-5's summer on-sale date, we're seeing a surge in interest and excitement from enthusiasts and journalists," said Jim O'Sullivan, president and CEO, MNAO. "Already, early MX-5 reviews have been overwhelmingly positive, and we expect the momentum that MX-5 has garnered to continue to build as drivers get behind the wheel of our fourth-generation sports car." Infused with SKYACTIV® TECHNOLOGY and KODO-Soul of Motion design, the 2016 MX-5 is smaller, lighter and more aggressive than its predecessor, with the base MX-5 Sport expected to outperform the sportiest previous road-going variants. However, even with its focus on delivering maximum driving enjoyment, the 2016 MX-5 boasts more creature comforts and a more functional interior than the vehicle it replaces.
