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.

Why Mazda did so well and Volvo so poorly in Consumer Reports survey

The poor performances of Tesla and all three domestic automakers got the headlines in Consumer Reports magazine's latest reliability survey, but there were other results that caught our interest. Tiny Mazda notched the biggest gain among the 29 brands included in this year's list, leap-frogging nine spots to No. 3. Buick, which was in the top 10 last year, fell 11 spots to No. 19, the biggest decline of any brand. And then there's Volvo, a brand often vaunted for its quality and reliability, dropping six spots to dead last. What gives? For starters, all three brands benefited or suffered in large part due to their relatively small portfolio of vehicles. So when raves or complaints rolled in for even one particular model, as was often the case, it weighed heavily on the entire brand. That's especially true when it involves a relatively high-volume, hot-selling model such as the Buick Enclave (more on that in a moment). Mazda fared as well as it did despite the CX-3 losing Consumer Reports' influential "recommended" status due to problems with its climate system, including leaks from the condenser and refrigerant unit that triggered a service bulletin from the automaker in late 2016. Deputy auto editor Jon Linkov said that scratch didn't hurt the overall brand, since the CX-9 crossover and MX-5 Miata both jumped up to replace it on CR's list of newly recommended vehicles, thanks to several back fixes Mazda made to both models. For Buick, the redesigned Enclave SUV earned a "Much Worse Than Average" rating after owners reported problems with the new nine-speed automatic transmission it shares with the Chevrolet Traverse as well as some issues with the climate system. There were issues with rough shifting, plus complaints about the torque converter that necessitated fixes to the computer or outright replacement. "Again, similar stuff that we saw with the Traverse: both first-year vehicles, similar powertrains," LInkov said. He said all-new vehicles or redesigns typically fare poorly in CR's reliability survey due to issues that are hard to suss out before vehicles go into everyday use by consumers. The top-selling Encore and Envision fared well, Linkov said, but were outdone by the Enclave's problematic transmission components. The Enclave was Buick's second best-selling model through September at 35,227 units. Then there is Volvo, about which there is one word to sum up its woes: infotainment.

Cars we're thankful we drove in 2019

We drove a lot of cars in 2019, and there's still a month to go. We drove them in our home office in Michigan, at our remote offices in Seattle, Portland, Ore., and Columbus, Ohio, and throughout the globe on myriad press launches. We could count them, but hey, that seems boastful.  Instead, we want to be thankful. Not only for the opportunity to do this wonderful task some might describe as a "job," but for the new, shiny cars that brighten our days (and most hopefully yours). We asked our fellow editors which car they were most thankful to drive in 2019 ... here are our answers. 2019 Hyundai Veloster N Performance Senior Editor Alex Kierstein Every once in a while a car comes along that changes the narrative on a company or its segment, and everyone scrambles to experience it for themselves. This year, for me, that car’s the Veloster N Performance, perhaps the most transformative car the companyÂ’s ever built. Everyone whoÂ’s driven it, here and elsewhere, says it captures all those intangibles that make great driving hatchbacks great. And IÂ’m thankful that I got a go in it before all of them left the fleet, because it does. It upends the segment long dominated by the GTI, a car that nails its brief. The N is rowdy and loud, sure, but it also has some of the most deftly tuned suspension IÂ’ve come across in a front driver. My advice: if youÂ’re in the market for something fun and unique, go test drive a Veloster N. I think youÂ’ll be thankful you did. 2019 Hyundai Veloster N View 47 Photos 2019 Audi E-Tron Senior Editor, Green, John Beltz Snyder IÂ’m pleased that I got to drive the Audi E-Tron. ThatÂ’s high praise for a year in which I also drove the stellar Jaguar I-Pace. The E-Tron, while not as sporty as the Jaguar, is excellently executed, and feels like a more refined, polished offering. ItÂ’s quick, whisper-quiet, comfortable, stylish inside and out, and incredibly sturdy. Some may lament that it doesnÂ’t do much to stand out from ICE vehicles, but I donÂ’t think it needs to. What it does need to do is win over the electro-skeptical, and I think Audi put its best foot forward with a crossover that can do just that, and more. So, yeah, not only am I thankful that I got to drive it, IÂ’m glad that itÂ’s compelling enough that itÂ’ll hopefully make potential customers feel the same. 2020 Audi E-Tron View 13 Photos 2013 Peugeot 508 West Coast Editor James Riswick My choice totally sucks.
