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.

Audi, Fiat squabbling over numbers and letters

There have been rumors and speculation and prognostications about a Nissan Juke- and Mini Cooper-fighting Audi Q2 since 2012. There have been the same for a performance-oriented Q4 since 2011, perhaps previewed by the TT Offroad concept shown last year at the Beijing Motor Show. Turns out that those two alphanumeric combos are the only ones missing from the series Q1 to Q9 in Audi's trademark stable, and the Ingolstadt company wants to get them to make its badge sequence and crossover lineup complete. But Fiat owns them, and rumor is, CEO Sergio Marchionne appears to have no interest in selling them. Fiat has used the Q2 and Q4 like trim badges, identifying whether a company product has two-wheel or all-wheel drive. They did it with the Alfa Romeo 159 sedan, and they do it now on the Maserati Quattroporte S and Ghibli S Q4 sedans. Car magazine says Marchionne "may not be categorically opposed to selling the rights," but he absolutely won't do it to any fiefdom in the Volkswagen empire, which would leave Audi a jilted suitor. Why is Sergio being so serious? VW Group CEO Ferdinand Piech first starting waving torches on the bridge between the two companies when he said Alfa Romeo could sell four times as many cars if Volkswagen owned it, then burned the bridge when it continued to publicize its desire to buy Alfa Romeo. VW followed that up by throwing salt on the land around the destroyed bridge with its aggressive pricing in Europe during the worst of the car sales slump there, which Marchionne said was causing a "bloodbath." VW's final flourish was to set the river itself on fire, when a press officer said Marchionne wasn't qualified to head the European Automotive Manufacturers Association (ACEA) and VW would quit the organization if he did take the top spot. That is why, putting it optimistically, Audi looks to have a grim chance of getting the Q2 and Q4 marques from the Italian. So long as he is in power, at least: Marchionne said he's walking away from the job in 2018. Audi might have a better chance bending the knee to, and generously rewarding, his successor.

2015 VW e-Golf coming to ZEV states for $35,445* this November

Is $6,465 too much to get someone thinking about buying a Nissan Leaf to opt for the Volkswagen e-Golf instead? That's the price difference between the current EV sales champion, which now starts at $28,980, and the just-announced price for the e-Golf, which will sell for $35,445 in the US when it arrives in about ten states (basically, the ZEV states that follow California's lead in zero-emission vehicle rules) this November and will qualify for the federal tax credit of up to $7,500. VW says that the extra money will get you "the most versatile electric vehicle in its class." There is only one trim line, the SEL Premium, which will be the first VW in the US with all-LED headlights. The car's powertrain numbers pretty much match the Nissan Leaf, though. The e-Golf has a 24.2-kWh lithium-ion battery (the Leaf has a 24-kWh pack) and a 115-hp, 199-pound foot electric motor (107 hp,187 lb-ft in the Leaf). The e-Golf's official EPA numbers are not yet available, but VW says it will have an "average range between 70 and 90 miles." The Leaf has an official EPA range of 84 miles. The e-Golf has a better onboard charger – 7.2 kW vs. 3.6 or 6.6, depending on your Leaf's options – and has SAE Combo fast charging capability as standard. VW is also working with 3Degrees to offset all of the emissions "created from production, distribution and charging of the e-Golf for up to approximately 36,000 miles of driving." VW also announced prices for its lightly facelifted 2015 Jetta today. The base model, the 2.0-liter S with a manual transmission, starts at $17,325 while the top-of-the-line model, the Hybrid SEL Premium, will set you back at least $31,670. The lowest-cost TDI is the S manual, which starts at $21,640 and features VW's new 2.0-liter diesel four. A new limited-edition 1.8 Sport model with a firmer suspension, tinted taillamps and rear spoiler starts at $20,895. All VW prices listed exclude VW's *$820 destination charge and you can find all the details on trim lines in the press releases below.
