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 says safety is a reason it's dropping Apple CarPlay, Android Auto

Update: GM sent us a statement as a follow-up to its original comments seen in this post: "We wanted to reach out to clarify that comments about GM's position on phone projection were misrepresented in previous articles and to reinforce our valued partnerships with Apple and Google and each company’s commitment to driver safety. GM's embedded infotainment strategy is driven by the benefits of having a system that allows for greater integration with the larger GM ecosystem and vehicles." The original story can be read in its entirety below.   General Motors announced its intention to remove Apple CarPlay and Android Auto functionality from its upcoming EVs earlier this year, and internet comments sections haven't been kind since. As the first of many EVs to follow – the 2024 Chevrolet Blazer EV – hits the market, GM is expanding on its initial explanations for dropping the tech. Motor Trend spoke with Tim Babbit, GMÂ’s head of product for infotainment, to learn more. Attributed to Babbit, from the story: “They have stability issues that manifest themselves as bad connections, poor rendering, slow responses, and dropped connections. And when CarPlay and Android Auto have issues, drivers pick up their phones again, taking their eyes off the road and totally defeating the purpose of these phone-mirroring programs. Solving those issues can sometimes be beyond the control of the automaker.” Babbit suggests that a world without Apple CarPlay or Android Auto will be a safer one, as folks wonÂ’t be looking to control their infotainment systems via their phones. However, Babbit also tells MT that this theory hasnÂ’t been tested in either the lab or the real world yet. Instead of using a navigation or music-playing app powered through your phone, upcoming GM EVs will use a Google-based infotainment system called “Ultifi” that runs a ton of integrated Google apps. Google Maps will be the native navigation app in the system; youÂ’ll be able to log in to Spotify or other apps to load your music up, and so on. The idea here is that youÂ’ll have all the same apps that were on your phone available but integrated within the infotainment system instead, and you'll be able to use voice controls to control every last bit of it with no need to reach for a phone. That sounds amenable in theory, but how consumers react to the removal of a feature that they know and love now is a risky gamble.

Chevy Colorado gets Midnight, Trail Boss editions

After introducing a gamut of special editions for the full-size Silverado, Chevrolet is offering a pair of new packages for its midsize Colorado. Following in the Silverado's footsteps, the Colorado Midnight Edition just blacks out all the things. There's a black grille, black Bowtie, and exclusive 18-inch wheels. They happen to be black, as well. In terms of functional changes, the Midnight Edition adds a spray-in bedliner, tonneau cover, and unique sill plates. Potential owners won't be limited on engine options and body styles here, as the blacked-out trim can be added to extended and crew cab bodies, in two- or four-wheel drive models, and with all of the pickup's available engines, including the upcoming Duramax diesel. The only limiting factor is the actual trim level – you'll need to settle for the mid-grade LT. Don't worry, though. The heftier, top-of-the-line Z71 will be offered with its own unique package, called the Trail Boss. As expected, it goes big on off-road character, with LED trail lighting and aggressive Goodyear Wrangler DuraTec tires. There are also black 17-inch wheels, newly flared fenders, side steps, and like the Midnight Edition, a blacked-out grille and spray-in bedliner. Also like the Midnight Edition, the only limit to adding the Trail Boss is that you opt for the Z71 trim. Engines, drivetrains, and body styles are not fixed. Look for both trucks at your local Chevrolet dealer this fall. Until then, scroll down for the official press release. 2016 Chevy Colorado Special Models Dressed to Impress Midnight Edition, Z71 Trail Boss complement capability with customized style 2015-08-03 DETROIT – On the street or on the trail, the 2016 Chevrolet Colorado's Midnight Edition and Z71 Trail Boss bring bolder choices to customers looking to make a visual statement with their truck. The special editions roll into Chevrolet dealerships this fall, with distinctly tailored appearances that blend custom design cues with Colorado's popular options and accessories. The Midnight Edition evokes the aesthetic of an urban tuner vehicle, while the Z71 Trail Boss is designed for terrain where the pavement ends. "These are aggressive editions of one of the country's hottest-selling truck, demonstrating the personalization that's possible with Chevrolet accessories, whether it's for the street, trail or both," said Tony Johnson, Colorado marketing manager.
