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 Green Car Of The Year finalists announced, run alt-fuel gamut

The 2015 edition of the Green Car of the Year award is following right in the footsteps of previous years with a variety of alt-fuel powertrains making the just-announced finalists list. You've got your plug-in vehicle (the BMW i3), your compressed natural gas (the Chevy Impala Bi-Fuel), your high-efficiency diesel (the Audi A3 TDI), your 40+ mile-per-gallon gas engine (the Honda Fit) and, finally, a car that can do a little bit of everything (the VW Golf). The Golf is available – at least in some parts of the US – with three different powertrains: a 2.0-liter diesel, a gasoline engine and all-electric drive. The Impala can burn either natural gas or gasoline in its 3.6-liter engine. The A3 is an efficiency champ, able to get 73.5 mpg on some European tests. The i3 can be a pure electric vehicle or come with a short range extending engine. And the Fit brings 41 miles to the gallon in a practical, affordable package. The GCOY award is announced every year at the Los Angeles Auto Show by Green Car Journal. The committee doesn't just take the fuel-saving technology into account, but also a vehicle's "availability to the mass market." Last year, the Honda Accord Hybrid/Plug-In Hybrid won top honors, following up on wins from the Ford Fusion models (plug-in hybrid and hybrid) for 2013, the Honda Civic Natural Gas for 2012 and the Chevrolet Volt for 2011. FINALISTS ANNOUNCED FOR 2015 "GREEN CAR OF THE YEAR"" Green Car Journal to Reveal Winner of 10th Annual Award at LA Auto Show" Press & Trade Days, November 20 LOS ANGELES, CA (October 21, 2014) – Green Car Journal has announced its five finalists for the magazine's high-profile 2015 Green Car of the Year® program. The 2015 models include the Audi A3 TDI, BMW i3, Chevrolet Impala Bi-Fuel, Honda Fit, and VW Golf. The Green Car of the Year® award, an honor widely recognized as the auto industry's most important environmental accolade, celebrates its 10th anniversary this year. An increasing number of vehicle models are considered for the Green Car of the Year® program each year, a reflection of the auto industry's expanding efforts in offering new vehicles with higher efficiency and improved environmental impact. Green Car Journal has been honoring the most important "green" vehicles every year at the LA Auto Show, since its inaugural award announced at the show in 2005.

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.
