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.

2013 Nissan NV200 hauls itself into McCormick Place

Nissan has already announced that its NV200 will be New York City's Taxi of Tomorrow, but now small businesses can also take advantage of the compact commercial van when it goes on sale this April. Unveiled at the Chicago Auto Show, the Nissan NV200 bound for North America has been stretched by almost eight inches compared to the same van that has been on sale in other global markets since 2009. The 2013 Nissan NV200 will be built in Cuernavaca, Mexico and sold at select Nissan dealerships with a starting price of $19,990 (*excluding the $845 destination charge).
At that price, the NV200 costs thousands less than lead competitors like the Ford Transit Connect and the Ram C/V Tradesman, although it does deliver less cargo volume than both as well. Despite its longer body, the NV200's 122.7 cubic feet of volume comes in just under the 129.6 cu-ft for the Ford and well under the Ram's 155.5 cu-ft cargo capacity. The split rear doors and dual side sliding side doors will give plenty of access to the NV200's cargo area, however, and Nissan says the van is wide enough to accommodate a standard pallet.
The NV200 was designed as much to be a mobile office as it is a hauler, so Nissan made the cabin as such. The passenger seat back can fold down creating a flat space for a laptop, and the center console has been specifically designed for hanging file folders. The base NV200S includes power windows, a two-speaker AM/FM/CD audio system and a 12-volt power outlet, while the NV200 SV (starting at $20,980) adds features such as cruise control, six floor-mounted cargo tie downs, power mirrors and door locks and remote keyless entry. Options include the $950 Technology Package (available on SV only and adds navigation, backup camera and satellite radio), $250 for Bluetooth and $190 for glass added to the rear cargo doors.

Nissan working on something radical for Le Mans

With Porsche joining Audi and Toyota at the front of the LMP1 grid at Le Mans next year, Nissan is the next to be throwing its hat (and considerable R&D budget) into the proverbial ring. But only if it's allowed to do something radically different, according to the latest report in Car magazine.
Just what that means remains to be seen, but Nissan is reportedly in active discussions with the ACO (the body that governs the race) to see how far it can stretch the regulations. The ACO has taken an intriguingly different approach to equalizing performance, mandating the maximum amount of energy that can be used per lap instead of telling teams what kind of engines they can use. That's how Porsche is entering with a four-cylinder engine, Toyota with a V8 and Audi with a diesel six. But when it comes to the shape of the car itself, the rules are considerably more restrictive.
Unfortunately the rules would prohibit Nissan fielding the ZEOD RC (with its narrow front track) in the LMP1 class, relegating it instead to the Garage 56 slot for experimental racers (which the DeltaWing filled before). And the realities of endurance racing would effectively prohibit anyone from fielding an all-electric racer. Within those confines, though, Nissan is eager to find enough wiggle room to make something both visually and technically different from other LMPs. And if the ACO won't let it do so at Le Mans, it could turn to another race or series (like the Nürburgring 24) that would.
