Carlos Ghosn's arrest casts doubt on future of Renault-Nissan alliance

For years, France's Renault and Japan's Nissan struggled to make money in the global auto business. Then came Carlos Ghosn, a Renault executive who helped to orchestrate an unprecedented transcontinental alliance, combining parts of both companies to share engineering and technology costs. Now Ghosn's arrest in Japan for alleged financial improprieties at Nissan could put the nearly 20-year-old alliance in jeopardy. Ghosn, 64, born in Brazil, schooled in France and of Lebanese heritage, is set to be ousted this week from his spot as Nissan chairman. He could also lose his roles as CEO and chairman of Renault, threatening the alliance formed in 1999 that's now selling more than 10 million automobiles a year. He's been "the glue that holds Renault and Nissan together," Bernstein analyst Max Warburton wrote in a note to investors. "It is hard not to conclude that there may be a gulf opening up between Renault and Nissan." In fact, Nissan's investigation into alleged misconduct by Ghosn is expanding to include Renault-Nissan finances, sources told Reuters — in a further sign that Nissan may seek to loosen its French parent's hold on their global carmaking alliance. Nissan told Renault's board on Monday it 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 said. Renault's board planned to meet Tuesday to discuss Ghosn's fate. "Carlos Ghosn is no longer in a position where he is capable of leading Renault," French Finance Minister Bruno Le Maire told France Info radio, calling on Renault's board to meet "in the coming hours" to set up an interim management structure. The French government owns 15 percent in Renault and has a say in its operations. Nissan's board is to meet Thursday to consider Ghosn's fate. Nissan has said it will dismiss Ghosn after he was arrested for allegedly abusing company funds and misreporting his income. That opens up a leadership void at the entire alliance, for which Ghosn officially still serves as CEO and chairman. Ghosn added Mitsubishi to the alliance two years ago after the tiny automaker was caught in a gas-mileage cheating scandal. Renault owns 43.4 percent of Nissan, which owns 15 percent of Renault, with no voting rights in a partnership that began in 1999. Since 2016, Nissan has held a 34 percent controlling stake in Mitsubishi Motor Corp.

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.

BMW tops Consumer Reports 2023 Brand Report Card

Feels like we wrote about Consumer Reports' 2022 Brand Report Car and 10 Top Picks a few weeks ago, but it was last April. So the mag is back with a ranked roster of 32 brands and 10 vehicles in four categories for your debating pleasure. Starting with the brands, last year's top three were Subaru, Mazda and BMW. This year, the Munich crew climbed two spots to win the prize thanks to "Superb road test scores and solid results in CR’s reliability and owner satisfaction surveys." Subaru narrowly fell to second, maintaining its four-year run in the top three. Mini, eighth last year, jumped five spots to get the last step on the podium. The rest of the top 10 were Lexus (up one spot from last year), Honda (down one spot from last year), Toyota (up three), Genesis (up 12), Mazda (down six), Audi (down three) and Kia (up eight). The magazine and testing outfit says its Brand Report Card "[reveals] which automakers are producing the most well-performing, safe, and reliable vehicles based on CRÂ’s independent testing and member surveys," and that "Brands that rise to the top tend to have the most consistent performance across their model lineups." Last year's top 10 had six automakers from Japan, three from Germany (giving Mini credit for England), none from the U.S. or South Korea, and five luxury brands. This year's list counts five makes from Japan, two from Germany because Porsche fell out of the top ten, two from South Korea, still none from the U.S., and four luxury brands. Buick again ranked as the best domestic, dropping to 12th after being 11th last year. The big mover was Lincoln, its 10-place jump up to 16th attributed to better reliability from the Corsair and Nautilus. Tesla's improved overall reliability saw it climb six spots to 17th. Dodge climbed one spot to 15th. Jeep got out of the penalty box in last to come second-to-last. Land Rover fell three places into the penalty spot.  CR's top 10 vehicle models The 10 Top Picks list is practically a new list. Only two holdovers made it to 2023, those being the Subaru Forester and Kia Telluride.
