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.

2017 Honda Ridgeline enters the landscape block war

In the test of pickup truck beds, if steel is apples and aluminum is oranges, Honda wants you to know that composites are pineapples. Chevy recently performed a test in which its own Silverado was pitted against its most obvious competitor, the Ford F-150. A loader dropped over 800 pounds of landscaping blocks into the two truck beds, and Ford's aluminum bed ended up with more damage than Chevy's steel bed. Check that test out right here. Honda apparently wasn't content to let Chevy throw stones alone. In a new test, the Japanese automaker replicated the block-drop test using its brand-new Ridgeline truck, which features a composite bed. As you'll see in the video above, there was very little damage to the high-strength plastic bed of the Ridgeline after a similar load of landscaping blocks were dropped from a loader. Without being on hand at any of these tests, we can't say with any degree of certainty that they match up in severity. But they all look pretty similar, and this is actually a test that Honda performed in front of journalists ( ourselves included) earlier this year. We visually inspected the composite bed of a Ridgeline after a demonstration just like the one on video above, and can confirm that there was basically no damage to Honda's truck. Chevy went an extra step by flinging a heavy toolbox into the Silverado and F-150; Honda didn't match that particular test. Does any of this matter? That's up to truck buyers and owners to decide, naturally, but we doubt anyone would actually dump a load like this into their own truck. And it's also worth noting that a heavy-duty spray-on bedliner would probably minimize damage to the metal surface below, whether steel or aluminum. If nothing else, it's memorable marketing.

Corvette Stingray designer lists five goals of new exterior shape

Redesigning an icon is a difficult task, especially when you've got a blank sheet of paper in front of you and the all-new C7 Chevrolet Corvette Stingray is intended to be your final objective.
General Motors has released a new short video featuring Kirk Bennion of the Corvette's exterior design team, talking about the challenges of sculpting Chevrolet's new flagship sports car and the five goals the team had to keep in mind as it worked. In the end, Bennion's team had the pleasure of seeing their hard work take center stage as the Corvette captured the world's eyes at the Detroit Auto Show earlier this year.
