VW sales increase 0.6% in September despite diesel scandal

Volkswagen was spared in the month of September from posting a sales disaster, but in reality, the impending doom and gloom is likely just postponed until October. According to VW, it delivered 26,141 vehicles to its dealerships last month, which represents a 0.6-percent gain over the same period a year ago. While up, that meager increase represents the smallest uptick of all major brands in the United States, which is currently in the middle of the best vehicular sales year in the last decade. Audi, the German automaker's mainstream luxury unit, saw a bigger gain at 16.2 percent with 17,340 total units sold, thanks in large part to the popularity of its crossover models. These numbers can't totally be taken at face value, however. In 2014, Labor Day weekend was counted as part of August's sales figures; in 2015, that traditional car-buying holiday fell early in September and is therefore partly responsible for the huge increases from all brands doing business in the United States. Remember, the diesel emissions scandal didn't hit the news until September 18, which means VW was free to sell its 2.0-liter TDI engine for the majority of the month. In other words, October is going to be the real indicator of sales reckoning as it will be the first full month that the brand can't sell its popular diesel models and the first since its emissions scandal broke. Still, TDI sales were down last month. VW reports a total of 3,060 sales of vehicles equipped with TDI engines, which represents 11.7 percent of total volume. That's nearly cut in half from the TDI's year-to-date volume percentage of 20.4 percent. "We would like to thank dealers and customers for the support of the Volkswagen brand," said Mark McNabb, chief operating officer for Volkswagen of America in a statement. "Volkswagen will continue to work diligently to regain trust and confidence in our brand." It's not yet clear exactly when VW will issue a fix to make its 2.0-liter TDI engine emissions legal, or when the EPA will recertify those models for sale. Once those two things happen, dealers will again be free to sell vehicles equipped with the powertrain, but even then it remains to be seen how consumers react when the sales ban is lifted.

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 quite interested in solid-state batteries for EVs

Volkswagen is about to make a decision about which advanced battery technology the automaker will seriously investigate to give its electric vehicles more range. VW will decide by July if it will use solid-state batteries made by US-based QuantumScape Corp. in future EVs, according to Bloomberg News. Last year, VW bought a five-percent stake in QuantumScape, which was founded by ex-Stanford University researchers. The lure is that QuantumScape's solid-state batteries may provide a single-charge range of as long as 430 miles. That's more than three times the current range of the VW e-Golf electric vehicle the company recently started selling to the public and is substantially longer than the single-charge range of the Tesla Model S electric sedan. The batteries are also fireproof, making VW's potential decision one with an eye towards more vehicle safety. Solid-state battery technology, in which solid lithium electrodes are used instead of liquid electrodes such as those in lithium-ion batteries, are the subject of research at other automakers and suppliers as well. Toyota says they could be here by 2020. Recently, the cordless vacuum cleaner maker Dyson acquired a $15-million equity stake in Michigan-based battery maker Sakti3 with the idea of using the startup's solid-state batteries in its products. General Motors also has a minority stake in Sakti3, which was spun off from the University of Michigan.
