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.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right." Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.

GM cutting back on powertrain warranty citing lack of interest

Generally, when a manufacturer offers a long, high-mileage warranty, it's a sign that it stands behind its products. On top of that, it's generally a selling point for consumers, who can rest easy knowing that any catastrophic failures will be picked up by the manufacturer. Considering those facts, it does seem rather strange that General Motors is slashing the mileage warranty on model year 2016 vehicles from Chevrolet and GMC. Instead of offering consumers a 100,000-mile warranty, GM will now only offer a powertrain warranty up to 60,000 miles. The five-year warranty period, though, remains unchanged. GM will also cut the number of free services being offered to Chevy and GMC owners, as well as Buick drivers, from four to two. "Through research, we have determined that when purchasing a new vehicle, included maintenance and warranty rank low on the list of reasons why consumers consider a particular brand over another," explained a memo sent to dealers by Chevrolet VP Brian Sweeney and his GMC counterpart, Duncan Aldred, and obtained by Automotive News. "As a result, we have benchmarked our competitors, reviewed our current offerings and have concluded the following modifications to align closely with our customers' needs and expectations." While the move might seem odd, Sweeney and Aldred are right – according to Automotive News, Ford, Honda and Toyota each offer a five-year, 60,000-mile powertrain warranty. As for what the money saved by trimming the powertrain warranty will go towards, a GM spokesperson simply told AN that the company will "reinvest the savings we will realize into other retail programs," some of which have been requested by consumers. What are your thoughts? Would a 40,000-mile reduction in a new vehicle's powertrain really turn you off from buying one? Even if it matched its competitors? Is GM better off spending its money elsewhere? Have your say in Comments.
