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 TDI Quick Spin [w/video]

There are two particularly great things about diesel-powered cars: torque and range. The 2015 Volkswagen Touareg TDI has both in spades. We put 190 miles on our test car, and upon return, the computer claimed we still had 490 miles to go. We weren't even averaging the EPA-estimaged 29 miles per gallon highway. Plus, that's in a sport-utility vehicle with tons of room and a whopping 406 pound-feet of torque. That said, our most recent adventure with the Touareg wasn't totally positive. This thing feels decidedly long in the tooth, despite a 2014 refresh. Driving Notes The Touareg TDI's powertrain really is the star of the show. The 3.0-liter, turbodiesel V6 has been in service since 2009, but it's still a dynamite engine. With 240 horsepower and 406 pound-feet of torque, the latter of which can be called upon at just 2,000 rpm, there's no shortage of thrust under your right foot. Turbo lag is an issue when you get aggressive with the throttle, but don't drive like a boob and you'll be fine. ZF's critically acclaimed eight-speed automatic delivers that power to all four wheels. But where other ZF-equipped vehicles deliver a crisper, sharper character, the TDI's trans is tuned for a far more relaxed driving experience. Upshifts are leisurely; the eight-speed keeps you right in the thick of the Touareg's broad torque curve. The suspension tuning follows a similar philosophy. It's far more comfortable than dynamic, soaking up all manner of bumps and general imperfections with aplomb. That said, the Touareg does not feel floaty or disconnected – just smooth. The greasy bits of the Touareg are very desirable, but the package they're wrapped in is less so. It's not that the interior or exterior designs are necessarily bad – fans of Earth tones will love our tester's Black Oak Brown Metallic paint and Cornsilk Beige interior – they're just kind of bland, or anonymous. The switchgear and buttons come from the Volkswagen parts bin, and while they're fine on a $20,000 Golf, these pieces aren't as appropriate in a vehicle that starts at more than twice the price. The dash plastics and faux wood don't look as nice as what's inside an Acura MDX, or even a Jeep Grand Cherokee. This mid-level Touareg TDI Lux starts at $57,580.

Hyundai plans Level 4 autonomy by 2021 in a fuel-cell car

SAN FRANCISCO — Silicon Valley startup Aurora announced on Thursday partnerships with Volkswagen AG and Hyundai to develop a self-driving system within their vehicles, the latest tie-up between global automakers and Silicon Valley tech companies. Aurora was founded in 2016 by robotics expert Drew Bagnell, Chris Urmson, who came from Alphabet Inc's Google, and Sterling Anderson, who formerly worked at Tesla. For Hyundai, Aurora's technology will be incorporated into custom-developed models and tested in markets including China. Hyundai said the first model to be used in testing will be its latest generation fuel-cell vehicle, debuting at the CES technology conference in Las Vegas next week. The model name of the car, shown above, will be announced then. Under the alliance, Hyundai plans to commercialize level 4 autonomous vehicles — which can operate without human input or even human oversight under select conditions — in unidentified "pilot smart cities" by 2021. This is the first announcement on a self-driving technology partnership by the South Korean carmaker, which has traditionally shunned tie-ups in favor of developing technology in-house. The strategy has raised investor concerns that it may be left behind in the race for self-driving and electric cars. A company spokeswoman said Hyundai has "various collaborations" under way in self-driving technology and would continue to pursue cooperation. In a statement, Volkswagen said Aurora's self-driving technology can be integrated over time across the automaker's brands and in different product categories, whether self-driving pods, shuttles, delivery vans or self-driving trucks. Aurora and Volkswagen said they had been working together over the past six months to integrate Aurora's sensors, hardware and software into the German carmakers' electric vehicles to develop self-driving ride services in cities. The non-exclusive partnerships mark the first deals for the young Silicon Valley company and show how some carmakers have chosen to partner with technology companies with more experience in artificial intelligence, deep learning and robotics in order to save time and money bringing self-driving cars to market. Within the self-driving car space, Waymo — formerly Google's autonomous program headed by Urmson — is offering something similar. The tech company has been working with Fiat Chrysler since 2016 to outfit its Chrysler Pacifica minivans with autonomous technology.
