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.

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.

VW Group plan puts Porsche in charge of a 'super-premium' division

An Automobile report looks into what's happening on the organizational and technical sides of the Volkswagen Group, and what those changes could mean for the premium brands. The wide-angle view is that Porsche appears to have been anointed to "coordinate the future activities" at Audi, Bentley, Bugatti and Lamborghini. Audi would cede Lamborghini guardianship to Stuttgart, and Ducati — via a new concern called Ducati Enterprises — would become the shepherd for VW's other Italian investments. Executives target Jan. 1, 2019, to complete the reshuffle. VW wants to save a boodle by tying up four of its five top-tier brands, and putting the one with the highest ROI in charge. Porsche, within its own house, wants to reduce expenditures by $2.3 billion per year over for four years, the savings already earmarked for improving internal processes like R&D and production. Having Porsche share those gains as well as lead development of platforms, components and future-tech strategies for the sister sports car brands could benefit everyone. In the near-term, the brands have their own plans: Bugatti CEO Stephan Winkelmann is said to want a Chiron Superleggera, a roofless and "completely reskinned" Chiron Aperta, and a track-only Chiron SS. The Superleggera could take the Chiron Sport's and Divo's Jenny Craig routines even further. The Aperta seems a natural successor to the Veyron Grand Sport, a natural evolution of the recently introduced Sky View roof, and a reskin might include numerous Divo cues. It's also said Bugatti's considering "an all-electric high-end model" in conjunction with Porsche, Rimac, and Dallara, but name one supercar or hypercar manufacturer that isn't considering a lightning-fast EV. Lamborghini, deep into work on follow-ups for the Huracan and Aventador, might get a bit of a bump with the new plan. The carbon "monofuselage" for the next V12 flagship is said to be too far developed and too complex to scrap. It puts two electric motors on the front axle, batteries in the middle, and a naturally aspirated V12 with around 770 horsepower plus another e-motor with 402 horsepower in back. The Huracan is said to get a version of the same carbon architecture at the moment, but the corporate reorganization might press pause on it. Automobile says options include continuing the Huracan/ Audi R8 twinning, but that depends on Audi saying "Ja" to a third-gen R8 with Lamborghini bones.
