Weekly Recap: Ferrari, Ford and Porsche power up for Geneva

Monday was Groundhog Day. Tuesday, apparently, was Sports Car Day. The Ferrari 488 GTB, the Ford Focus RS and the Porsche Cayman GT4 all debuted within hours of each other ahead of their rollouts at the Geneva Motor Show. Three sporty machines, three vastly different approaches – and a lot of implications for enthusiasts. That's a day worth repeating. It also illustrates the opportunities automakers see in the performance market, which is expected to grow in the coming years. Ford estimates the segment has expanded 14 percent in Europe and surged 70 percent in North America since 2009. The Detroit Auto Show was evidence of this, and performance cars of every stripe debuted, including the Acura NSX, Ford GT, Alfa Romeo 4C Spider and several others. This isn't a fad. Performance cars aren't going away. The question is why? Stricter CAFE standards are looming in the United States, as are tighter emissions regulations in Europe. And no one expects gas prices to remain low in America. None of this matters for sports cars, and automakers are increasingly using them to elevate their images. That's why Dodge rolled out two 707-horsepower Hellcats last year. It's why Ford has decided to resurrect the GT for road and track. It's why in the depths of bankruptcy, General Motors continued work on the Chevrolet Corvette Stingray, not to mention the Z06. "Great brands are made one car at a time," Ford of Europe president Jim Farley said at the reveal of the Focus RS. Still, companies make those cars for different reasons. View 5 Photos Mainstream brands like Ford and Dodge want to build cars that get people talking, excite their bases and drive more potential customers into the showroom. They probably don't buy a Focus RS or a Hellcat, but suddenly the regular Focus hatch looks a bit hotter, and that V6 Charger seems to be just a touch more muscular. The halo of performance is alive and well in the eyes of automakers and their customers. "It's one of the most effective catalysts for ingenuity and innovation," said Joe Bakaj, vice president of product development for Ford of Europe. That also leads to a trickle-down effect. Some of the technologies inevitably make their way to other products. It's hard to think the new all-wheel-drive system in the Focus RS that distributes torque front to rear and side to side won't be used in other vehicles. It's different for Ferrari and Porsche.

Carlos Ghosn: What misconduct is he accused of?

TOKYO — Japan was shocked by news that Nissan Motor Co. Chairman Carlos Ghosn, who was widely respected for rescuing the carmaker from near bankruptcy, was arrested on Monday for alleged financial misconduct. Nissan said that Ghosn, who is also chairman and CEO of Renault and chairman of Mitsubishi Motors, would be fired from his post as Nissan chairman on Thursday. What is Carlos Ghosn accused of? Nissan CEO Hiroto Saikawa told a packed press conference on Monday night that the company had found that Ghosn had been using corporate money for personal purposes and under-reporting his income for years in official company filings to the Tokyo Stock Exchange. Another board member, Greg Kelly, was also deeply involved in the misconduct, Nissan said. Saikawa said he couldn't elaborate as the cases are being investigated by prosecutors, who have declined to comment. Prosecutors said that Ghosn and Kelly conspired to understate Ghosn's compensation over five years starting in fiscal 2010 as being about half of the actual 9.998 billion yen ($88.9 million). Public broadcaster NHK said Nissan paid billions of yen to buy and renovate homes for Ghosn in Rio, Beirut, Paris and Amsterdam, citing unnamed sources. The properties had no business purpose and were not listed as benefits in TSE filings, NHK said. Ghosn, 64, has not been formally charged. The Asahi newspaper reported that he and Kelly had submitted to prosecutors' questions after getting off a plane on Monday afternoon at Tokyo's Haneda Airport. Saikawa confirmed they had been arrested. Ghosn and Kelly have not been seen since, and their exact whereabouts are not known. Suspects are typically taken to the Tokyo Detention Center, which is linked to the Tokyo District Public Prosecutors Office. How did this come to light? Nissan's Saikawa said Ghosn's alleged improprieties came to light through a whistleblower, after which the company began an internal investigation and informed prosecutors. Japanese media reports say the informant is a member of Nissan's legal department. The Asahi reported, without citing sources, that the informant gave the prosecutors information in a plea bargain, implying the person may have provided evidence in exchange for a lighter sentence. How much control did Carlos Ghosn have? After becoming CEO of struggling Nissan in 2001, Ghosn was hailed as the automaker's savior by implementing an aggressive cost-cutting plan.

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.
