Nissan shows self-cleaning car coated in nano paint

Washing the car is an activity like mowing the lawn that some people love and others find to be an absolute chore. For the latter group, Nissan may have an answer. Nissan is testing a nano-paint coating that could make the car wash a very infrequent place to visit.
Shown on a European Note hatchback, the key is a special layer of super-hydrophobic and oleophobic material called Ultra-Ever Dry that is sprayed over the paint. It creates a protective layer between the body and environment, and it means that when dirt or water come into contact with the car, the gunk just sheets away.
Nissan admits that the coating is still early in testing. The key will be if the stuff can actually last for the long term, and the company will be analyzing it over the coming months to see how it will react in different conditions. At the moment, the automaker has no plans to offer Ultra-Ever Dry as a standard feature, but it may make it available as an aftermarket addition in the future. Scroll down to watch the video of Nissan testing the stuff in some very dirty conditions.

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.

Renault wants to merge with Nissan, then go after Fiat Chrysler

The late Sergio Marchionne used to say consolidation would be the only way to compete against the biggest global carmakers. The company looks certain to fulfill that goal, but perhaps not in the way he intended. The Financial Times reports that Renault wants to begin merger talks with Nissan in the next 12 months. Assuming a merger gets completed, the plan is for the combined company to then pursue another merger, with Fiat Chrysler a prime target. Renault, Nissan, and Mitsubishi have been busy since cutting ties with ex-alliance boss Carlos Ghosn. They formed a new alliance board with Renault chairman Jean-Dominique Senard at the helm, Renault has shrunk the size of its board while Nissan added more outside directors, and the two agreed to a new governance structure to ease operational decision making. All three automakers have walked away from Ghosn-era goals to sell 14 million cars and find 10 billion euros in savings by 2022. New strategic plans for all three car companies are in the works. With stability in sight, it's said Senard wants to succeed where Ghosn failed — a full-fledged merger between Renault and Nissan with talks to begin "as soon as possible." Ghosn's pursuit of a merger last year in attempt to make the 20-year-old alliance "irreversible" is part of what led to his downfall, with Nissan executives including CEO Hiroto Saikawa against the push. The new effort is presented as larger scale being the only way for the alliance to take on companies like Volkswagen and Toyota. But the Nissan-Renault-Mitsubishi trio sold 10.76 million cars around the world last year, second to Volkswagen with 10.83 million sales, ahead of Toyota with 10.39 million. If Nissan hadn't suffered a 2.8 percent dip in sales, the alliance would have taken the top spot. If a little scale is good that means more is better, right? Pulling Fiat Chrysler into the alliance would add around 5 million annual sales, and would be another move in Ghosn's footsteps. The former honcho is said to have "held talks with FCA" about some kind of union within the past three years. The French government, which has a 15 percent stake in Renault and double voting rights, shut down the initiative. It's not clear if FCA will be an independent company by the time a potential Nissan-Renault merger closed, though.
