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.

Infiniti teases November debut of new QX55 crossover-coupe

Infiniti will officially unveil its new QX55 crossover-coupe via social media on Nov. 11, Nissan's luxury subsidiary announced early Wednesday. Infiniti is calling it a return to the segment which the company helped pioneer when it launched the FX crossover back in 2002.  "With a roofline and visual elements inspired by the iconic Infiniti FX, the QX55’s provocative design will fuse the stance and versatility of a premium midsize crossover with the sleek profile of a sports coupe," Infiniti's announcement said. "Beyond its provocative looks, the QX55 will also feature innovative technologies designed to empower, engage and connect luxury customers to the road ahead." The announcement was accompanied by the above teaser image, which depicts the QX55's tapered liftgate. It's quite a bit more conservative than the previously released design sketch suggested, but certainly looks the part.  The QX55 is one of five new vehicles Infiniti plans to launch in the next three years. It was first teased last August during Monterey Car Week. While Infiniti has been leaning heavily on the heritage of the original FX (which later became the QX70) since releasing that first design sketch, the QX55 will actually have little in common with its spiritual ancestor. While they may share fastback SUV looks, the QX55 will be based on the QX50 — a modern, front-wheel-drive crossover with small, efficient engines. The FX was derived from Infiniti's sport sedans and coupes, and even boasted a V8 option for much of its existence. Production of the new crossover-coupe was slated to begin in June, but was reportedly pushed back due to complications at its production facility in Aguascalientes, Mexico. The facility is a joint-venture project between Mercedes-Benz parent company Daimler and Nissan, and produces several other front- and all-wheel-drive vehicles for both companies.  Related Video: This content is hosted by a third party.

Nissan ZEOD RC on track and from behind the wheel

The Nissan ZEOD RC hybrid racecar has had mixed success in its competition life. It was invented to do a completely electric, high-speed lap at the 24 Hours of Le Mans, which it was able to do in practice. However, when the big event actually came, the car lasted less than an hour before it had to bow out with transmission issues. Nissan hasn't completely given up on its experiment, though. The experience (and possibly some of the tech) is going to help with the GT-R LM racer next year, and now the ZEOD is getting its chance to see how it handles the Top Gear test track.
Unfortunately, it's not The Stig piloting the ZEOD; instead, the magazine's motoring editor Ollie Marriage is the lucky man for the job. The car's sharp shape seems to be a good metaphor for how it handles because it just seems to dart around the track. Its tiny, turbocharged 1.5-liter engine with 400 horsepower and two electric motors put out a claimed 750 horsepower, and that seems like plenty for the relatively short Top Gear course.
As usual of Top Gear, the cinematography here is fantastic, and a second video shows off a single lap of the course from around the car. It's amazing to watch, especially with its big screen constantly showing the camera view out of the rear. Scroll down to see both.
