New Chevrolet Silverado to be revealed on Facebook on Thursday

There's not much to see here, but if you're one of those waiting for the reveal of the 2014 Chevrolet Silverado 1500, above is the teaser image that Chevrolet posted on its Facebook page. We've seen the truck in form-fitting camo before, and even less can be made out here beyond those seriously punchy Silverado-esque fenders and the knowledge that the projector-beam headlamps teased previously do indeed work. We'll have to wait until Thursday for a full perusal of the "bold exterior design" and "careful attention given to every detail" we've been promised.
Gathering intel and rumors, magnesium and aluminum contribute to the Silverado's weight loss plan, the purported "High Country" top-tier trim will contribute to luxury pickup truck competition and profit margins and the next-generation small-block V8 will contribute to improved fuel economy. On the engine note, there have been rumors of available V6 engines, and when Facebook user John Jones asked "Where's your answer to that EcoBoost Chevy?", the Bowtie replied "stay tuned on the 13th. We think you'll be pleased...".
Along with the "Raise the Bar" tag, Chevrolet says of the Silverado, "You asked, we delivered." You can watch the reveal live on Chevrolet's Facebook page at 9:30 am EST, this Thursday, December 13. The GMC Sierra 1500 will also be there, and we'll see both in person at the Detroit Auto Show in January.

2016 Chevy Camaro Convertible coming on June 24

With the new sixth-generation Chevy Camaro now upon us, Chevrolet is gearing up to drop the top on the new 2016 Camaro Convertible, previewed in this latest teaser video. There isn't much to go on from this short clip – the new convertible will feature a fully automated folding roof that will retract at the push of a button. Beyond that, we expect it to carry over the same features as the hardtop version we've already seen. Chevy is due to unveil what it calls "the most innovative Camaro Convertible ever" just a couple of days from now, so watch this space.

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.
