Nissan does its best Google Glass impression with 3E headgear [w/video]

The jury may still be out on whether it'll be legal to drive with Google Glass on your nose, but that doesn't mean automakers are going to sit around waiting to see which way the wind blows in one jurisdiction or another. Mercedes-Benz, for example, is already working on ways to integrate its infotainment system into Google Glass, but Nissan is taking things a step further by developing its own wearable tech.
The device is called Nissan 3E, and we don't have much information to go on at this point - just a couple of images, a terse press release and the highly stylized (and rather painful-looking) video below. The Japanese automaker lists internet connectivity and communication as the primary features. But we'd have to assume that, if an automaker is developing it, the device would have some relevance to, you know... driving.
The possibilities are endless, extending from turn-by-turn directions and track information to vehicle metrics and intuitive control of the car's auxiliary controls. We'll have to wait until we get to Tokyo to find out more, but between this and the smartwatch concept it revealed in Frankfurt, Nissan seems to be on a bit of a gadget streak lately.

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.

Datsun's lackluster initial sales fall below Tata Nano

When Tata introduced the Nano back in 2008, everyone was amazed at how cheap it was. They called it a game changer, but no game was changed. In fact, it took Tata five years to sell the 250,000 units it had the capacity to build in a single year. As it turns out, even buyers in what economists call "developing markets" like India aren't necessarily interested in buying an ultra-cheap automobile. And now it appears that Nissan may be falling into the same trap.
A little over a year ago, Nissan revived its old moniker Datsun to serve as a budget brand - similar to what ally Renault did with Dacia. Its lineup (consisting of models like the Go hatchback, Go+ minivan, On-Do sedan and Mi-Do hatch) is largely based on old architecture, packaged with little more than basic equipment and sold at rock-bottom prices. But Bloomberg reports that, even in the brand's core markets like India and Indonesia, the new Datsuns haven't been selling.
According to local industry figures, Datsun has sold fewer than 10,000 units of its $5,100 Go hatchbacks in India since its introduction back in March. Maruti Suzuki, by comparison, sells twice that many of its similarly priced Alto hatchbacks every month. In fact, after peaking in April, Datsun only sold 607 units in India this past July, dipping 77 percent to drop below even the number of Nanos which Tata sold that month.
