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.

Aston Martin DBX and the craziest car redesigns | Autoblog Podcast #716

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick. They chat about slumming it in the Aston Martin DBX, the brand's first SUV, which they didn't have terribly high expectations for yet utterly blew them away. Riswick in particular notes it's one of the best cars he's ever driven, describing it as a family GT car. They then switch to a very different family vehicle: the 2022 Kia Carnival, and the unique second-row seating arrangement we've dubbed the "Captain Kirk chair." Greg has also been driving the Chevrolet Tahoe Premier. They also chat about two of Riswick's recent features: the 20 craziest car redesigns of the past 20 years and the best cars for snow.  Autoblog Podcast #716 Get The Podcast Apple Podcasts – Subscribe to the Autoblog Podcast in iTunes Spotify – Subscribe to the Autoblog Podcast on Spotify RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown Cars we're driving Aston Martin DBX 2022 Kia Carnival 2022 Chevy Tahoe Features 20 craziest car redesigns of the last 20 years Best cars for snow Feedback Email – Podcast@Autoblog.com Review the show on Apple Podcasts Autoblog is now live on your smart speakers and voice assistants with the audio Autoblog Daily Digest.

Millionth Corvette now being restored after sinkhole damage

Among the original American sports cars that were damaged by the sinkhole at the National Corvette Museum over a year ago was a 1992 convertible that was the millionth Vette made. And now that milestone vehicle is starting its restoration process. The landmark Corvette's rehabilitation is being carried out by the GM Design Center in Warren, MI, by a team of skilled craftsmen and technicians. The crew is more accustomed to building prototypes and concepts, but will face a new challenge in bringing this millionth Corvette back to its original condition. The white-over-red convertible was one of eight Corvettes that were swallowed up by the sinkhole at the museum in Bowling Green early in the morning on February 12, 2014. Five will be preserved in their compromised condition as part of a display demonstrating the effects of the sinkhole, while the remaining three were earmarked for restoration. The Design Center team has already completely the restoration of the 2009 Corvette ZR1 "Blue Devil" prototype, while the remaining 1962 Corvette will be restored by the museum.

The restoration crew is part of GM's Mechanical Assembly group at the Design Center, which typically spends its time building prototype and concept vehicles. The white 1992 Corvette is a challenge because rather than build an all-new vehicle from the ground up, the workers are trying to preserve the original appearance of a production vehicle. It is the second of three sinkhole-damaged Corvettes that Chevrolet has pledged to restore. The first, a 2009 Corvette ZR1 prototype known as the Blue Devil, was only lightly damaged and was returned to its original condition last fall. The National Corvette Museum will oversee the restoration of the third car, a 1962 Corvette. Five other Corvettes swallowed by the sinkhole will remain in their as-recovered state to preserve the historical significance of the cars. They will become part of a future sinkhole-themed display at the museum. Sinkhole summary On Wednesday, Feb.
