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.

Volkswagen bringing new Touran minivan to Geneva

Volkswagen is bringing a wealth of new metal to the Geneva Motor Show this year. Unfortunately little if any of it is ever likely to reach American shores. There's the new Passat Alltrack, the Golf GTD Variant and a trifecta of new vans: the facelifted Caddy, the revised Sharan and this, the new Touran. Smaller than the Sharan, the Touran is Germany's top-selling minivan and boasts over 1.9 million units sold to date. It was introduced to the VW passenger van lineup in 2003 and was replaced in 2010 with an all-new model. What you're looking at here is the third-generation Touran, based on VW's ubiquitous new MQB architecture. Most obvious is the new sheet metal that makes it look sharper and more in step with the rest of the German automaker's lineup compared to the model it replaces. But there's more to the new Touran than its skin. It's also nearly five inches longer, with most of that length added in the wheelbase to give it a more commodious cabin that's also been updated with the latest equipment and offers room for up to seven passengers. Despite the larger size, it's a good 136 pounds lighter than the outgoing model, so it promises better performance in both its driving dynamics and its environmental credentials. Prospective customers (in markets where the Touran is sold) will be able to choose from a range of three gasoline and three diesel engines ranging from 108 horsepower up to 187, burning as much as 19 percent less fuel than the outgoing model's lineup thanks to features like stop/start engine management and brake force regeneration. There's even a sporty R Line package to give it a little visual aggression. For better or worse, though, the US market will almost certainly be left out: reached for comment, our source at VW USA pointed out that the Touran and Sharan aren't big enough to fill the shoes left by the Routan - but that the upcoming three-row crossover will. Volkswagen presents the new Touran - Germany's best-selling MPV completely redeveloped - More room; smart new design - New engines up to 19 per cent more economical Volkswagen presents the new Touran. The completely redesigned MPV was showcased before an audience of international media representatives at the Autostadt in Wolfsburg, not far from the production site where the popular family car is made. The interior of the new model has undergone a significant increase in size and is highly configurable.

Rimac is reportedly close to buying Bugatti from the Volkswagen Group

Croatia-based Rimac is finalizing a deal to purchase Bugatti from the Volkswagen Group, according to an unverified report. If the rumor is accurate, the sale would propel Rimac to the top of the automotive industry, guarantee that Bugatti's future is electric, and mark the beginning of Volkswagen's efforts to divest its empire. Executives in Wolfsburg gave the deal the green light in September 2020, according to anonymous sources who spoke to British magazine Car, but the company's supervisory board hasn't approved it yet. Selling the French company isn't as simple as sending company founder Mate Rimac an email with an account number. Insiders explained Volkswagen would likely trade Bugatti and all of its assets for a significant stake in Rimac that would be transferred directly to Porsche, which already owns 15.5% of the brand. Officials hope to increase that figure to about 49%, meaning Bugatti is theoretically worth about 33.5% of Rimac, which was founded in 2009. Bugatti told Autoblog it can't comment on speculation. Mate Rimac gave us a similar answer. Rumors of a Bugatti sale have hovered around the automotive industry for several years, and they've never materialized. In theory, spinning off the brand would be relatively easy because it's not as deeply integrated into the Volkswagen Group as its sister companies. It doesn't share its W16 engine with another carmaker, for example. And yet, Car speculates Lamborghini, SEAT, ItalDesign, Bentley, and Ducati will also be sold in the coming years, leaving Volkswagen with its namesake division, Skoda, Audi, Porsche, Scania, and MAN. Volkswagen is having an estate sale to fund the development of electric, autonomous, and digital technologies. Its downsizing will send ripples through the auto industry. Porsche could move upmarket if it doesn't have to worry about stepping on Lamborghini's toes, for example. Spinoffs are always risky, so some companies may not survive if they're not bolstered by economies of scale. As of writing, there's no word on who will pick up the brands being divested under this scenario. And, keep in mind none of this is official. Volkswagen hasn't commented on the report. We'll update this developing story as more information becomes available.
