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.

The techie choice | 2017 Toyota Prius Prime Quick Spin

The Prius nameplate has been inexorably tied to the green car scene for a long time now. When Toyota unleashed the Prius Prime upon the world, we said it was the best Prius yet. But this is no longer a world where Toyota's hybrids are automatically crowned king. Our recent time with the Hyundai Ioniq trio was a stark reminder that the economical, eco-conscious competition is getting stiffer. We put some miles on a Prius Prime to see how our recent Ioniq Plug-In Hybrid test colors our view of Toyota's prime contender. Our first impression: the Prius design is very clean and inorganic. As sterile as it feels, the design appears to have a lot of actual thought behind it. Our Advanced trim tester is spiritually in touch with the mobile gadget culture, with a huge touchscreen, digitization of seemingly everything, and white and black glossy plastic aesthetic. It's a tech-heavy design that will likely seem familiar to those of us who have been interfacing with Apple designs for the past 10 or so years. The Ioniq Plug-In Hybrid, on the other hand, remains truer to the look and feel most drivers expect from their commuters. It's less about user interface, modes, and drive data, and more about just getting behind the wheel and driving. The Ioniq Plug-In Hybrid hardly even distinguishes itself from its plugless counterparts, opting to go green under cover rather than the in-your-face futurism the Prius projects. It retains the traditional instrument cluster in front of the driver, too, which the Prius Prime lacks. In the Toyota, you'll have to look around the car for the right display with the information you're looking for – there's the huge central touchscreen with all its menus, as well as smaller displays above it on the dash – or you can find your speed on the HUD. The Prius is composed in its handling, but doesn't provide much of the sensory feedback that makes one feel connected to the chassis. The steering feels super artificial, but the car stays fairly flat in the corners without providing too much feedback through the seat of your pants. Hyundai's offering, though, proved to be a surprisingly willing dance partner in the corners. While feeling equally as capable as the Prius, the Ioniq's sense of connection through steering and suspension made the act of stitching one turn after another together enough to get our blood pumping. Sport mode makes the Prius Prime slightly livelier, though.

2019 Toyota Corolla Hatchback, Volvos earn IIHS Top Safety Pick rating

It's time for another round-up of recent IIHS crash tested cars. The trio this time include the 2019 Toyota Corolla Hatchback, 2019 Volvo XC90 and 2018 Volvo S90. All three have earned one of the highest ratings from the IIHS, the Top Safety Pick. And all three continue a trend of very safe cars having slightly below-par headlights, preventing them from earning the highest Top Safety Pick+ rating. Of these three cars, the Corolla Hatchback has the most impressive scores. It earned the highest "Good" rating in every single crash test, including the difficult small-overlap passenger-side collision. It also received the top score for access to LATCH anchors for child seats. The standard forward collision prevention technology also brought home the best score possible, stopping the car before a crash at speeds up to 25 mph. The headlights themselves weren't particularly bad either, earning the second-highest score of "Acceptable" with both the standard and optional LED headlights.

Both Volvos shared similar scores to the Corolla Hatchback, with "Good" ratings for all crash tests they participated in, and top rank for their standard forward collision technology. Both vehicles were not tested for the passenger-side small overlap collision, so there is no score in that area. Both also received the "Acceptable" rating for LATCH anchor access. In the headlight department, the XC90 earned "Acceptable" scores for both of its available headlights, and the S90 received an "Acceptable" for its optional lights, while the standard ones were rated as "Marginal."
