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.

Nissan recalls nearly 20,000 NV vans over gearshift issue

Nissan is recalling 18,800 NV vans built between December 20, 2010 and January 4, 2013. Certain 2012 and 2013 models equipped with a steering-column-mounted transmission shift levers may have been built with improperly installed shift mechanisms.
If the NV's gear selector plate lock clip wasn't installed correctly, normal road vibration could result in a gear position indicator that does not match the actual gear selection. As a result, when the driver selects 'park,' the transmission could still be in gear or in neutral, and roll away. The National Highway Traffic Safety Administration says this condition greatly increased the risk of accident and injury.
Nissan will inspect the gear selector lock clip and replace the part if necessary free of charge. Owners can expect to be notified once the recall campaign begins on April 8, 2013. Read the full recall notice below for more information.

2016 Nissan Leaf with 107-mile range will start at $35,050* [UPDATE]

Here we go. Without making any huge leap into a second-gen model, Nissan has upgraded the 2016 Nissan Leaf from the 2015 model with a big range increase and a more durable battery. According to the new EPA numbers, the new Leaf will go 107 miles from a 30-kWh battery pack. That's going to get people's attention, since the current Leaf has an 84-mile range from a 24-kWh pack. You will still be able to get an 84-mile Leaf in the 2016 model year, since Nissan is keeping the S trim level with the lower, 24-kWh pack size. If you opt for the more expensive SV or SL trims, then you'll not only get the 27-percent greater range, but also a battery pack that is slightly heavier (by 46 pounds) and has more modules (eight vs. four) but the same number of cells. The two packs are the same size. In the end, the EPA rates the 30-kWh with 124 city, 101 highway and 112 combined MPGe fuel economy, while the S trim keeps the 126 city, 101 highway and 114 combined MPGe of the 2015 models. All the new 2016 Leafs keep the same 80-kW AC synchronous motor from earlier models. It still offers 107 horsepower and 187 pound-feet of torque. Prices for the new Leaf start at $35,050 for the Leaf SV (up from $32,950 for the 2015), $37,640 for the Leaf SL (up from $35,970) and $28,060 for the Leaf S (no change from 2015). All prices include $850 delivery charge but not the potential federal tax incentive of $7,500. The 2016's exterior is virtually identical to the 2015, aside from some new colors with names like Forged Bronze, Coulis Red and Deep Blue Pearl. Nissan is offering a few upgrades on the inside, though. There's a new graphic interface display on the 7-inch color screen (5-inch on the S trim) and a new "beam forming microphone" that should make the car's voice recognition better. The information that is displayed on the screen has also changed, with the charging screen info being updated every 12 miles. Given that some (but not all) of the rumors of this Leaf range bump turned out to be true, what do you all think of the talk of a 250-mile Leaf in about three years? UPDATE: The original headline quoted the price of the SL model instead of the less expensive SV, and has now been changed to accurately reflect the starting price of the SV. Both SL and SV come standard with the new 30 kWh battery, while the S model comes standard with the smaller 24 kWh pack. Thanks to those who pointed out this discrepancy!
