These 'blind' automotive world record stunts have to stop

Drivers setting world records "blind" – wearing a blindfold or with something obscuring the windshield – is the new thing for some reason. First it was an Alfa Romeo Giulia setting a blind lap at Silverstone with help from a spotter trailing behind, and now this: a stunt man doing a J-turn within a narrow path with nothing but a Nissan Juke's cameras guiding him. He matched the "sighted" J-turn record, flipping the car around in a space about 7 inches longer than the car. I have two issues with these stunts. First, there are just too many world records. Yeah, I said it. Are these meaningful? Is someone else likely to ever attempt this feat? No, because it's just marketing, both for the manufacturer and whoever's still trying to sell those annual books. Stuff like the fastest production car is fine with me. Heck, I'll even take unofficial Nurburgring times – the kind where the drivers can actually see. Second, I'm all for stunts, but do something cool! And preferably something that could only be performed with that particular car, if you're going to make an ad out of it. Yes, the Juke has an Around View Monitor system, which stitches together feeds from four cameras to make it look like the car is being filmed by a drone hovering overhead. I happen to love 360-degree cameras – they let you see things that are just not visible from the driver's seat and make parking and low-speed maneuvering really easy. But the Juke isn't the first car to offer one, and the feature isn't even new to the car. Nissan was at least forthright enough to admit that this professional driver (on a closed course!) had a bunch of practice. But this really says more about his precision driving skills than about the car, or the camera. And just so we're clear, you really shouldn't try to park a car without looking out the windows, even if you have fancy cameras. So what's next? Pretty soon there will be a record for blindest blind stunt. Let me know when someone actually does something interesting. Related Video:

Renault board names Ghosn stand-ins, as tensions with Nissan increase

PARIS/TOKYO — French carmaker Renault tapped its chief operating officer and a senior board member to fill in for embattled boss Carlos Ghosn, after an investigation by alliance partner Nissan led to his arrest on suspicion of financial misconduct. Thierry Bollore, Ghosn's operational second-in-command, will become deputy chief executive, while lead independent director Philippe Lagayette assumes the function of interim chairman, Renault said after a board meeting late on Tuesday. But the board refrained from firing Ghosn while awaiting more detail on the allegations — in a decision that could also buy more time for an accelerated, permanent succession process. "Mr. Ghosn, temporarily incapacitated, remains Chairman and Chief Executive Officer," Renault said in a statement. "During this period, the board will meet on a regular basis under the chairmanship of the lead independent director." Ghosn, one of the car industry's best-known leaders, was arrested on Monday after Nissan said he had engaged in years of wrongdoing, including personal use of company money and under-reported earnings. The Japanese company plans to remove him as chairman on Thursday. The French government, Renault's biggest shareholder, had begun to distance itself from Ghosn, calling for new interim leadership before the meeting, as the Japanese investigation expanded to include Renault-Nissan alliance finances. "Carlos Ghosn is no longer in a position where he is capable of leading Renault," Finance Minister Bruno Le Maire said earlier in the day. "Renault has been weakened, which makes it all the more necessary to act quickly." Statements by Le Maire, Renault and its board all echoed French preoccupations over the future of the alliance first articulated by President Emmanuel Macron within hours of Ghosn's arrest on Monday. Following talks between Le Maire and his Japanese counterpart Hiroshige Seko on Tuesday, the ministers reaffirmed their "shared wish to maintain this winning cooperation." But in a sign that Nissan may now seek to loosen its French parent's hold on the partnership, the Japanese company informed Renault it also had evidence of potential wrongdoing at Renault-Nissan BV, the Dutch venture overseeing alliance operations under Renault's ultimate control, three people with knowledge of the matter told Reuters.

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.
