VW stock plummets as Euro markets open

The fallout from Volkswagen's installation of an emissions "defeat device" on nearly 500,000 diesel-fueled models in the US is already hitting the automaker hard on the German stock exchange. At one point, the share price plummeted 23 percent to erase the equivalent of $17.6 billion in value. Things eventually bounced back slightly to a still severe 19.23 percent loss, according to Bloomberg as of this writing. The scandal couldn't come at a worse time for chairman Martin Winterkorn. The VW supervisory board takes up the issue of renewing his contract on September 25, Bloomberg reports. If things get bad enough, the door could be open for a new boss to step in. Dealers in the US might start feeling the pain from this, as well. Affected 2015 VWs that are still at showrooms are now under a stop sale. Until the issue is straightened out, the Environmental Protection Agency isn't certifying the company's 2016 diesel models with the 2.0 TDI, either. The diesel emissions problem was first discovered by research from West Virginia University and the International Council on Clean Transportation. In some cases, the engines can produce 40 times more nitrogen oxides than allowed. The automaker could be on the hook for $18 billion in fines for the breach, but the actual figure is expected to be lower. In response, Winterkorn has issued a public apology and ordered an independent investigation into what happened. The EPA and California Air Resources Board have also been looking into the situation. This could become an international problem, though. According to The Detroit News, European authorities might begin similar inquires to check the automaker's diesel emissions there.

Skoda plans big investment into electric cars as part of rebound effort

PRAGUE — Czech carmaker Skoda, part of the Volkswagen Group, said on Wednesday it would invest around 2.5 billion euros over the next five years on future technologies, with more than half going to electric vehicle investment. The Czech Republic's largest exporter is hoping for a rebound in 2021 from a global car sales drop but faces uncertainty over the coronavirus pandemic and a semiconductor shortage rattling the industry. "This year is likely to be another big challenge," finance director Klaus-Dieter Schuermann said. "We expect Skoda Auto's group performance to improve, with sales revenue significantly above the level of last year." Skoda reported on Wednesday a 54.5% drop in 2020 operating to 756 million euros ($894 million). Sales revenue dropped 13.8% to 17.1 billion euros. Global deliveries remained above 1 million cars for a seventh straight year despite a 19% drop after production outages at the outset of the pandemic and a fall in China, its biggest single market. Chief Executive Thomas Shaefer said the car company was managing the semiconductor shortage "but it will follow us for awhile" and the impact was not visible yet. Skoda's core market in Europe would be electric in the future, Shaefer said, although it was still not time to completely switch away from traditional models, which include the launch last year of a new generation of its flagship Octavia model. It has also started production of the all-electric Enyaq iV model, which is a version of Volkswagen's ID.4. Skoda plans investments of 1.4 billion euros into electromobility development as part of its five-year investment plan. Investments will also go into digitalization activities and plant modernization. Related video: Green Volkswagen Skoda Electric

VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.
