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.

Japan carmakers vouch for safety of some Kobe Steel parts

TOKYO — Four Japanese automakers on Thursday said they found no safety issues with aluminum parts supplied by Kobe Steel Ltd, allaying some concerns that falsified quality data on products from the steelmaker had compromised their vehicles. Kobe Steel shares surged after the car makers' statements, but the steelmaker still has to contend with a U.S. Justice Department probe, while checks continue at hundreds of companies involved in complex supply chains spanning the globe. Japan's third-biggest steelmaker admitted earlier this month it falsified specifications on the strength and durability of aluminum, copper and steel products, along with materials for optical disks. The falsifications stretch back for more than 10 years, a senior executive told Reuters this week. Since then, global automakers, aircraft companies and other manufacturers have scrambled to identify potential hazards in their products. Toyota, Honda, Nissan and Mazda said that hoods and other exterior parts used in their cars which were made from aluminum directly supplied by Kobe Steel were safe. Kobe Steel shares ended the day nearly 7 percent higher but are still down by more than a third since it announced the data falsification. Automakers are still making checks on other parts, including those that they received through their parts suppliers. "We confirmed that the materials satisfy applicable statutory standards, and our own internal standard, for key safety and durability requirements for vehicles," Toyota said in a statement. Toyota, one of the world's largest automakers, identified aluminum plates supplied by Kobe Steel for the hoods and rear hatches of Toyota and Lexus brand vehicles. Though outside the automaker's specifications, they were still safe to use. While Subaru and other carmakers said they were still investigating the issue, the announcements by Toyota, Honda, Nissan and Mazda suggest that Kobe Steel's cheating scandal may have a limited impact on product safety."SERIOUS SITUATION" Nonetheless, the company's fate hangs in the balance while checks are being carried out. It must report to Japan's industry ministry by around the end of next week on any safety concerns and provide a more extensive account of the problems a fortnight later. Industry leaders have reached a consensus that Kobe Steel is in a "serious situation," a senior Japanese manufacturing executive told Reuters.

Mazda Raceway gets first new MX-5 Cup as pace car

Mazda's motorsports department officially finished the first example of its new MX-5 Cup racer. But while the rest of the fleet will be used in the Global MX-5 Cup championship, this initial unit has been designated for another purpose. It's been dedicated to serve as the new pace car for Mazda Raceway Laguna Seca. Based on the latest ND-generation MX-5, the Cup racer was previewed in racing spec this past November ahead of its debut at the SEMA show. Though we've still yet to see the final spec sheet, it clearly benefits from key upgrades to the rolling stock, not to mention the added roll cage, racing buckets, and more. The pace car also features emergency lighting and a livery designed by Mazda and applied by Sticky Fingers Design out of Huntington Beach, CA. The beefed-up little roadster will join a cadre of pace cars used at the legendary Northern California circuit. Other pace cars in the fleet include a Mazda6, RX-8, CX-5, and the previous Miata. The season is winding to a close at Laguna Seca, with the Pirelli World Challenge finale and Mazda Road to Indy still set to take to the track next month.

(August 13, 2015) – Mazda Motorsports used the annual car-fest known as the Rolex Monterey Motorsports Reunion to roll out the first production 2016 Mazda MX-5 Cup race car. This particular vehicle is guaranteed to lead races as it will be the newest pace car in the Mazda Raceway Laguna Seca fleet of Mazda safety vehicles. The 2016 Mazda MX-5 Cup race car follows a 26-year history of the MX-5 Miata in motorsports. The first race cars to be sold to customers will be used in the 2016 Global MX-5 Cup, known in the U.S. as the Battery Tender Mazda MX-5 Cup. With the 2016 racing season still many months away, placing the first production race car into pace car duty allows Mazda to gather additional durability data while showcasing it in front of one of the most influential motorsports crowds of the year. "For Mazda, this weekend is the perfect blend of past, present, and future," noted John Doonan, director of motorsports for Mazda North American Operations. "We are celebrating our motorsports heritage on the track with our vintage race cars.
