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.

CES 2020 and Carlos Ghosn | Autoblog Podcast #609

Welcome to a new decade of the Autoblog Podcast. In this week's episode, Editor-in-Chief Greg Migliore is joined by Senior Editor Alex Kierstein and Senior Editor, Green, John Beltz Snyder. First they talk about their early impressions of CES 2020 in Las Vegas, in particular how interesting Sony's Vision-S Concept is. Then they talk about the intriguing saga and daring escape of former Nissan boss and global fugitive Carlos Ghosn. After that, they turn their attention to what they've been driving, including the Genesis G70, Chevy Blazer and Hyundai Santa Fe. Finally, they help a listener pick a new fun toy to replace an unloved Porsche Cayman in the "Spend My Money" segment.

Nissan's dismal 2019: Where does Japan's struggling brand go from here?

Auto sales have gradually slowed from their peak during the boom years that followed the global recession, but Nissan's rapid decline stood out even in a year when few high-volume manufacturers had much to be excited about.  Of the "Japanese 3," Nissan's 2019 performance was by far the most troubling. Through November, when the company last posted its global sales figures, its volumes were down 8 percent compared to 2019. Here in the United States, its full-year numbers were down 9.9% in an industry that slid just a hair more than 2 percent overall.  Meanwhile, Honda managed a slight increase in U.S. sales (0.2%) and Toyota, much like the industry in general, finished the year down approximately 2%. Like Nissan, Honda and Toyota have remained committed to cars — including compact and midsize sedans — and have a comprehensive portfolio of offerings in the key SUV and crossover segments.   On paper, Nissan's lineup checks all the right boxes. From the subcompact Kicks up to the Armada, it has something for sale in virtually every possible nook and cranny of the people-mover segment, but almost all of these trucks (and trucklets) took a beating in 2019. Only the baby Kicks managed to improve on its 2018 sales, which isn't saying a whole lot, considering it was barely sold in 2018 to begin with.  In fact, the bonus volume contributed by Kicks helps obscure just how poorly some of Nissan's key offerings performed last year. Combined Rogue and Rogue Sport sales slid 15%; Murano was down more than 18%; the Pathfinder and Armada managed to pace the general industry, dropping 2.8 and 1.9%, respectively, but the astute reader will note at this point that we've yet to single out any bright spots. The news was even worse on the truck side. Frontier was down 9.1%. Titan? Down 37.5%. Crossovers and SUVs are selling. Trucks, even from import brands, are also selling. Toyota's mid-size Tacoma was up in 2019; both it and the full-size Tundra still more than tripled the volume of their Nissan competitors. Further muddying the waters, Honda managed its year-over-year volume increase without selling a full-sized pickup at all.  What, then, is Nissan's problem? To borrow an oft-used phrase, "It's the product, stupid." The most striking evidence of this issue is the Rogue, which competes in the compact crossover segment — a collection of vehicles that essentially sell themselves.
