Chevy Malibu Hybrid wins 2016 Connected Green Car of the Year

From the Washington Auto Show today, Green Car Journal's Ron Cogan announced three different fuel-efficient vehicle awards. They were: 2016 Connected Green Car of the Year: Chevy Malibu Hybrid 2016 Luxury Green Car of the Year: Volvo XC90 T8 2016 Green SUV of the Year: Honda HR-V The Volvo was nominated in two categories, but it did not win the Connected Green Car of the Year. Speaking of non-winners, the other green SUV finalists were the BMW X1 XDrive28i, Hyundai Tucson, Mazda CX-3, and Toyota RAV4 Hybrid. The other Luxury Green Car finalists included the BMW x5 xDrive40e, Lexus RX 450h, Porsche Cayenne S E-Hybrid, and the Mercedes-Benz C350e. Finally, the Audi A3 e-tron, BMW 330e, Toyota Prius, and Volvo XC90 T8 were the runners up for Connected Green Car. 2016 Connected Green Car of the Year, Green SUV of the Year, Luxury Green Car of the Year Winners Announced WASHINGTON, Jan. 21, 2016 /PRNewswire/ -- Green Car Journal has announced the winners of its prestigious 2016 Green Car Awards at a press conference held today during the Washington Auto Show's Public Policy Day in Washington DC. Distinguished as 2016 Luxury Green Car of the Year™ is Volvo's new XC90 T8. The Chevrolet Malibu Hybrid tops the field as 2016 Connected Green Car of the Year™ and Honda's HR-V earns Green Car Journal's 2016 Green SUV of the Year™. "These are stand-out vehicles in an increasingly sophisticated and appealing field of 'green' cars," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "To make the cut as a finalist is a real achievement in itself considering the considerable competition in the market today. Rising to the top as award winners means these three exceptional vehicles set a benchmark in the auto industry's effort to create vehicles that are desirable and efficient, while also achieving environmental milestones so important for our driving future." The Green Car Awards are a key feature of The Washington Auto Show, the "public policy show" on the auto show circuit and one that puts a priority on safety and sustainability. "We are extremely proud of our partnership with Ron Cogan, whose eagerly anticipated suite of awards help shape the national conversation on the innovations that will drive our industry and country forward," said Geoff Pohanka, chairman of The Washington Auto Show.

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.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.
