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.

1956 Corvette SR-2 factory racer profiled

The Chevrolet Corvette has earned its place as America's sports car, capable of taking on the best the world can throw at it. Much of that winning reputation was earned with victories on the track. Now, there was a chance to own an early piece of the nameplate's motorsport history in the form of a 1956 Corvette SR-2 racer, but some deep pockets were necessary to get it, with an estimate of $6.885 million. The story behind the SR-2 is fascinating. In 1956, famous General Motors designer Harley Earl's son was racing in a Ferrari. Obviously, that wasn't going to work given his father's position within the automaker, and Harley and Corvette engineer Zora Arkus-Duntov got to work on a faster racecar. Three were made. This one was reportedly the first, and for 1957 it also received a fuel-injected V8 making a claimed 331 horsepower and four-speed manual gearbox, according to "Corvette Mike," the owner and seller. The SR-2 went on display in Scottsdale, AZ appropriately timed to coincide with the big Barrett-Jackson auction there that wrapped up this weekend. The car wasn't part of that event; instead marque specialist Mike Vietro sold the racer as a private treaty sale. Company spokesperson Troy Worrell told Autoblog both the bids and identities of the bidders will remain undisclosed. The video above goes into even deeper detail about this rare, finned Vette or check out the car's full description for even more info.

GM delays truck plant shift so workers can watch Detroit Lions NFC Championship game

It would be difficult to overstate just how big of a deal it is for the city of Detroit and its residents (and residents of southeast Michigan in general) that the Detroit Lions not only made it convincingly into the NFL playoffs but found significant success in defeating the Los Angeles Rams in the Wildcard round and then the Tampa Bay Buccaneers the following week. But if there's one thing we can point to as an automotive-minded group, it's this: General Motors has delayed the start of the third shift at its Flint Assembly plant so that workers won't have to miss any part of the game. To emphasize the magnitude of this decision, it's important to note that the Chevrolet Silverado HD and GMC Sierra HD are built at the plant, and the popularity and, perhaps more importantly, profitability of those heavy duty trucks is so high that it's the only GM plant in Michigan that runs a third shift, as pointed out by the Detroit Free Press. The delay is roughly an hour in total, and workers won't be paid for that missing time. We doubt there will be any complaints. Granted, this isn't the first time GM has delayed starting a late shift due to a big sporting event. In prior years, delays have been recorded for some Super Bowls and for the in-state Michigan vs. Michigan State rivalry game at GM facilities in Lansing, Michigan. Still, GM's statement on why it would hold off production of such a lucrative pair of vehicles explains it better than we can: "We recognize the Detroit Lions playing in the NFC Championship game as a rare, unique opportunity that warrants this temporary schedule adjustment to allow employees to enjoy the game and make it to work on time." It's not GM's only show of Lions pride. Take a close look at the General Motors logo currently being displayed at the Renaissance Center, GM's headquarters in Detroit. General Motors is displaying its Motor City pride with a subtle logo redesign to honor the Detroit Lions as they continues their Super Bowl hunt.

Ford has yet to provide a comment, but Stellantis, makers of the Ram truck and Jeep SUVs, has confirmed it will be running normal schedules at all of its facilities. For now, there's only one more question that needs answering: What if the game goes to overtime?
