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.

Rising aluminum costs cut into Ford's profit

When Ford reports fourth-quarter results on Wednesday afternoon, it is expected to fret that rising metals costs have cut into profits, even as rivals say they have the problem under control. Aluminum prices have risen 20 percent in the last year and nearly 11 percent since Dec. 11. Steel prices have risen just over 9 percent in the last year. Ford uses more aluminum in its vehicles than its rivals. Aluminum is lighter but far more expensive than steel, closing at $2,229 per tonne on Tuesday. U.S. steel futures closed at $677 per ton (0.91 metric tonnes). Republican U.S. President Donald Trump's administration is weighing whether to impose tariffs on imported steel and aluminum, which could push prices even higher. Ford gave a disappointing earnings estimate for 2017 and 2018 last week, saying the higher costs for steel, aluminum and other metals, as well as currency volatility, could cost the company $1.6 billion in 2018. Ford shares took a dive after the announcement. Ford Chief Financial Officer Bob Shanks told analysts at a conference in Detroit last week that while the company benefited from low commodity prices in 2016, rising steel prices were now the main cause of higher costs, followed by aluminum. Shanks said the automaker at times relies on foreign currencies as a "natural hedge" for some commodities but those are now going in the opposite direction, so they are not working. A Ford spokesman added that the automaker also uses a mix of contracts, hedges and indexed buying. Industry analysts point to the spike in aluminum versus steel prices as a plausible reason for Ford's problems, especially since it uses far more of the expensive metal than other major automakers. "When you look at Ford in the context of the other automakers, aluminum drives a lot of their volume and I think that is the cause" of their rising costs, said Jeff Schuster, senior vice president of forecasting at auto consultancy LMC Automotive. Other major automakers say rising commodity costs are not much of a problem. At last week's Detroit auto show, Fiat Chrysler Automobiles NV's Chief Executive Officer Sergio Marchionne reiterated its earnings guidance for 2018 and held forth on a number of topics, but did not mention metals prices. General Motors Co gave a well-received profit outlook last week and did not mention the subject. "We view changes in raw material costs as something that is manageable," a GM spokesman said in an email.

As VW electrifies, it questions the role of Lamborghini, Bugatti, Ducati

FRANKFURT — Volkswagen needs to change to stay relevant in the electric and digital vehicle era and will announce "important steps" to that end before the close of the year, Chief Executive Herbert Diess said on Wednesday. "Volkswagen needs to change: From a collection of valuable brands and fascinating combustion-engine products that thrill customers with superb engineering — to a digital company that reliably operates millions of mobility devices worldwide," Diess told shareholders at the company's virtual general meeting. Vehicles need to stay in contact with customers, offer new services and comfort functions on a weekly or even daily basis, he said. "We will take further important steps to set the course for this in the rest of 2020," Diess said. Senior executives told Reuters the company is reviewing what role its high-performance brands Lamborghini, Bugatti and Ducati will play as the company increasingly focuses on electric, digital and autonomous vehicles. Volkswagen, which also owns VW, Audi, Porsche, Seat and Skoda, is looking at whether it has the resources to accelerate development of electric platforms for smaller brands at a time it is investing billions to transform its more mainstream cars. Asked whether Ducati, which is known for making noisy combustion-engined motorbikes, has an electric future, Markus Duesmann, who oversees research and development for the group, said: "It will not take long until we see an electric Ducati." Whether Ducati, which is a medium-sized premium motorbike brand, would offer an electric variant, depends on whether a bike could offer range comparable to a combustion-engined variant, Duesmann said. Advances are being made in battery technology which could make this possible, he added. Separately Frank Witter, the company's chief financial officer, in response to a question about whether a sale of Lamborghini is planned, said Volkswagen does not comment on speculation about potential divestments. Lamborghini's Chief Executive Stefano Domenicali this week announced his departure from the sports car maker to take on a new job as president of Formula One. VW needs cash Volkswagen is reviewing the future of these three high-performance brands as part of broader quest for more economies of scale as it shifts to mass producing electric cars, senior executives told Reuters.
