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.

FCA-Renault merger faces tall odds delivering on cost-cutting promises

FRANKFURT/DETROIT — Fiat Chrysler Automobiles and Renault promise huge savings from a mega-merger, but such combinations face tall odds because of the industry's long product cycles and problems translating deal blueprints into real world success, industry veterans told Reuters. BMW's 1994 purchase of Rover, and Daimler's 1998 merger with Chrysler both made sense on paper. The companies promised to hike profits by combining vehicle platforms and engine families. Both combinations proved unworkable in reality, and were unwound. Renault and Nissan, which have been in an alliance since 1999 designed to share vehicle components, have only managed to use common vehicle platforms in 35% of Nissan's products despite an original target of 70%, according to Morgan Stanley. FCA and Renault have raised the stakes for themselves by ruling out plant closures. That increases the pressure to achieve more than $5 billion in promised annual savings from pooling procurement and research investments. The two companies have yet to fill in many of the blanks in the merger plan put forward by Fiat Chrysler. Renault's board is expected to act soon to accept the proposal, but that would lead only to a memorandum of understanding to pursue detailed operational and financial plans. A final deal and the legal combination of the two companies could take months to complete if all goes well. Pressure to cut automotive pollution is driving the latest round of consolidation. Automakers are looking at multibillion-dollar bills to develop electric and hybrid cars and cleaner internal combustion engines. Fiat Chrysler and Renault are betting they can design common electric vehicle systems, then sell more of them through their respective brands and dealer networks, cutting the cost per car. Developing all-new electric vehicles can bring more opportunities to share costs from the outset, industry experts said. "With the emergence of connected, autonomous, electric and shared vehicles, carmakers face immediate investments, so new opportunities for sharing costs have emerged," said Elmar Kades, managing director at Alix Partners. However, most electric vehicles lose money. This is a challenge for city car brands in Europe in particular. Both Renault and Fiat rely heavily on this segment for sales.

Japan may aid carmakers facing U.S. tariff threat

TOKYO — Japan is considering giving carmakers fiscal support including tax breaks to offset the impact from trade frictions with the United States and a sales-tax hike planned for next year, government sources told Reuters on Wednesday. Going into a second round of trade talks with the United States on Sept. 21, Japan is hoping to avert steep tariffs on its car exports and fend off U.S. demands for a bilateral free trade agreement that could put it under pressure to open politically sensitive markets, like agriculture. "If the trade talks pile pressure on Japan's car exports, we would need to consider measures to support the auto industry," a ruling party official said on condition of anonymity because of sensitivity of the matter. The auto industry accounts for about 20 percent of Japan's overall output and around 60-70 percent of the country's trade surplus with the United States, making it vulnerable to U.S. action against Japanese exports. Japan's biggest automakers and components suppliers fear they could take a significant hit if Washington follows through on proposals to hike tariffs on autos and auto parts to 25 percent. Policymakers also worry that an increase in the sales tax from 8 percent to 10 percent planned for October 2019, could cause a slump in sales of big-ticket items such as cars and home. Prime Minister Shinzo Abe has twice postponed the tax hike after the last increase from 5 percent in 2014 dealt a blow to private consumption, which accounts for about 60 percent of the economy. To prevent a pullback in demand after the tax hike, the government may consider large fiscal spending later when it draws up its budget for next year, government sources said. "One option may be to greatly reduce or abolish the automobile purchase tax," one of the government sources said. The government is also considering cuts in the automobile tax and automobile weight tax to help car buyers, the source added.
