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.

If VW defaults on loans it may sell Bentley or Lamborghini

If something goes catastrophically wrong with Volkswagen Group's recent $21 billion loan, brands like Bentley or Lamborghini could hit the auction block. According to two insiders to Reuters, the beleaguered German automaker agrees with its creditors to sell assets if the company somehow can't pay back the debt in a year. One of these anonymous people claimed the company hasn't yet deliberated over what to sell. However, the sources were willing to speculate that the power engineering portion of Man could be among the first to go. "Volkswagen may also consider divesting luxury car brands Bentley and Lamborghini or motor bike brand Ducati, although these units don't really move the needle," an insider said to Reuters. VW Group negotiated with the banks earlier this week to get the massive loan. The cash is necessary as a buffer in case the automaker doesn't have enough money on hand to repair vehicles or settle upcoming fines. VW would reportedly issue bonds in the spring to begin paying the debt. The company's bills will start racking up quickly in the new year. German authorities mandate a recall there in early 2016, and repair campaigns in the US for the 2.0- and 3.0-liter diesel engines are inevitable. There are also hundreds of class-action lawsuits to settle. The company needs to resolve its CO2 emissions scandal in Europe, too. In response to these financial threats, VW management created a cost-cutting plan to slash the research and development budget by $1.1 billion next year.

2015 Volkswagen Touareg [w/video]

The second-generation Volkswagen Touareg has been in production since 2010, and is therefore staring down the last part of its model cycle. To keep buyers interested, the company has undertaken a refresh of its upscale midsize SUV. As is typical of these things, the changes include some exterior and interior rejuvenation, as well as increased content levels and a slight uptick in price. The basics of the styling changes are pretty straightforward. The 2015 Touareg can be pretty easily spotted versus the outgoing model by way of its four-bar chrome grille, a cleaner headlight design, bigger VW badge and a completely new lower front clip. (I got one photo of the old and new models side-by-side for my Twitter followers before we rolled out on the drive.) There's also a thin strip of chrome that runs around the bodywork, standard LED taillights and a selection of three new wheel styles and five new paint colors. Inside, I found it harder to spot the changes, old to new. The Touareg's switchgear has been updated and there's a new frame for the infotainment display, but there's no piece that stands out and says "new model year!" Powertrains and mechanical bits all carryover from the 2014 Touareg, too. But there were a few functional changes to the vehicle, primarily in the new Driver's Assistance Package, for me to take note of as I took a lap of my favorite Ann Arbor, MI driving route. Drive Notes Let me start with the newest news then, the Driver Assistance pack. Volkswagen will sell you this suite of safety gear on either the mid-level Lux or the top-end Executive trims, for $2,500. The package included adaptive cruse cruise control, "Front Assist" for emergency braking situations, lane-keep assist and blind spot monitoring. If the contents of that package don't strike you as revolutionary, you're not alone. Some or all of the technologies that are new to the Touareg have been around other showrooms – and other VW family products – for quite a while. Still, they're nice to have as options. All of the driver assistance features that I was able to test worked as advertised, too. The adaptive cruise uses cameras, radar and ultrasonic sensors, so it isn't likely to be impacted by inclement weather, which is nice. I also appreciate that the lane-keep assist (which offers the driver a haptic buzz to the steering wheel when straying out of the lane) can be turned off, or turned down in terms of intensity and reaction time.
