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.

VW makes $23K on every Porsche sold, more than Bentley or Lamborghini

It's a good time to be in the luxury car business. In Volkswagen Group's financial report for the 2013 fiscal year, it is revealed that that Porsche enjoyed an operating margin of 18 percent. That means the Stuttgart brand made on average about $23,200 per car sold, according to BusinessWeek. Bentley wasn't far behind, and Audi (which was combined with Lamborghini) posted a 10.1 percent margin. This compares to only around 2.9 percent for the Volkswagen brand.
"Luxury brands are on fire," said Dave Sullivan, an industry analyst at AutoPacific. He said that the average profit margin is between six and eight percent. Brands like Porsche and Bentley have the benefit of competing in rarefied markets. Buyers looking at one their vehicles have fewer models to shop against and don't care as much about price. They can also charge more for options, which further boosts income, according to BusinessWeek.
In a way, we should be more impressed by the continued success from Audi. Its models generally have direct competitors in every segment from the other premium automakers. Plus, their buyers aren't the captains of industry who are shopping for a Bentley. Still, the Four Rings is leading rivals in sales so far this year.

Hyundai tops VW and Buick in China, survey says

You may be aware of the long-time competition in China between Volkswagen and Buick, but another brand apparently should be in that conversation too: Hyundai. In a recently published annual consumer survey, the Korean company actually took the top spot to beat out its German and American rivals in second and third, respectively. The results were part of the China Brand Power Index that interviewed 11,500 people around the nation and was paid for by the country's Ministry of Industry and Information Technology. While Hyundai proved popular with voters, its sales haven't necessarily shown that yet. According to Bloomberg, the brand had falling numbers in China for the first quarter of the year. Even Ford outsold the South Korean automaker in the same period, despite scoring lower on the survey. Meanwhile, Audi ranked as the populace's favorite luxury brand, which is hardly a surprise given the Four Rings' strong sales in China. In January alone the automaker saw a 15-percent boost in volume there. Parent company VW's strong performance was somewhat more surprising, though. State media severely criticized the German automaker in March, and customers protested last year for the allegedly poor handling of a recall.
