Watch Evo pick its 2015 Car of the Year in this epic video

With just a few days left in 2015, it's the perfect time to check out Evo's annual Car of the Year test to determine the greatest performance vehicle of the last 12 months. The writers' picks for the 11 finalists spanned a breadth of engaging models and included: Peugeot 208 GTi by Peugeot Sport, Lamborghini Aventador SV, Seat Leon Cupra Sub8, McLaren 675LT, Porsche 991 GT3 RS, Porsche Cayman GT4, Honda Civic Type R, Ferrari 488 GTB, Chevrolet Camaro Z/28, Lotus Evora 400, and Mercedes-AMG GT S. For the venue to test the mettle of these performance machines, Evo stuck close to home this year and visited the twisting roads at the beautiful north coast of Scotland. Racing brothers Marino and Dario Franchitti also came along for the ride to provide two more voices in the competitive challenge to determine a winner. Evo's video explains why each model deserves to be among such rarified company but doesn't gloss over their faults either. There can be only one winner, though. We don't want to spoil it, so check out the clip for magnificent views of these performance machines through the Scottish countryside.

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.

GM forced to cut truck production amid semiconductor shortage

WASHINGTON — General Motors said Wednesday it will cut some truck production in North America because of the ongoing global semiconductor shortage. The largest U.S. automaker said its Flint Assembly plant that builds the Chevrolet Silverado HD and GMC Sierra HD trucks will operate on one production shift the week of July 26. GM said its Ft. Wayne Assembly plant in Indiana that builds the Chevrolet Silverado 1500 and GMC Sierra 1500 model trucks will be idled next week. GM's Silao Assembly plant in Mexico that also builds the Chevrolet Silverado 1500, Cheyenne (for the Mexico market) and GMC Sierra 1500 will also suspend production next week. All three plants are expected to resume regular production the week of August 2. Related video:
