This is Nissan's 2014 Detroit Auto Show concept

During a media event in Los Angeles today, Nissan flashed a few images of a new concept car that will be unveiled at the 2014 Detroit Auto Show in January. According to Shiro Nakamura, senior vice president and chief creative officer of design and brand management at Nissan, this unnamed concept has a "very strong design signature" and shows "[Nissan's] future design direction."
It's certainly quite sleek, this concept, yet specific elements like the front fascia and taillamps are evolutionary steps from what we're seeing on some of Nissan's newest products. Those rear lamps look like sleeker versions of what the Sentra wears, and that grille appears to be a more stylized version of what the next-generation Rogue has been seen sporting.
As for what, exactly, this concept previews, that's still up in the air, though our best guess is that it hints at a Maxima successor. After all, Nissan did confirm to us that a new Maxima is currently in development, and showing this concept in early 2014 lines up with our predictions that the next-generation sedan should arrive in time for the 2015 model year.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

North Carolina now charging $100-per-year EV road-use fee

Tobacco Road just got a little more expensive for drivers of electric vehicles such as the Nissan Leaf and Tesla Model S. This year, North Carolina started instituting an annual $100 road-use fee for electric-vehicle drivers in order to close at least a little of the budgetary shortfall for road maintenance in the Tar Heel State, the News Observer reports. North Carolina legislators failed to green-light a hybrid-vehicle fee of $50 a year, which may have made a little more of a dent in the state's road funding. As it is, about 1,600 EVs are registered in North Carolina, meaning that the state will collect about $160,000 in such fees this year. And while some in the state are concerned that the fee could hurt EV adoption, others say it's fair because of the $7,500 in federal tax credits EV buyers get. Oh, and the fact that EV drivers don't pay gasoline taxes. Either way, the fees are a proverbial drop in the bucket, as North Carolina's transportation shortfall is estimated to average about $2 billion a year during the next three decades or so. Other states are starting to charge EV drivers a road-use fee as well. Last February, Washington State began instituting its own electric-vehicle fee of $100 per annum, and a number of other states are considering similar policies.
