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.

Silverado HD, Touareg V10 TDI face off in diesel tug-of-war

A couple weeks ago, we watched a Chevrolet Silverado get dominated by a Dodge Ram Heavy Duty in a fullsize pickup tug-of-war, but in that truck's defense, Chevy's Vortec gas engine was no match for the torquey Cummins turbo diesel. For our next round of vehicular tug-of-war, a Duramax-powered Silverado HD takes on Volkswagen Touareg V10 TDI.
Now, on paper, putting the Duramax V8's 365 horsepower and 660 pound-feet of torque up against the V10's 310 hp and 553 lb-ft looks like an easy win for the Bowtie, but unfortunately, this battle has a similar result as the Dodge versus Chevy video, with the Silverado smoking its tires trying to move forward as it gets pulled backwards. Put another way: YouTube 2, Chevy Silverado 0.
It just goes to show, though, that big tires, bolt-on fender flares and goofy smoke stacks don't improve your towing abilities. Besides, what did the Silverado driver expect when the Touareg V10 TDI has towed a Boeing 747 in the past?

MindDrive cruises California with 1972 Karmann Ghia EV

If you need a bit of inspirational EV goodness, spend some time watching the collection of videos we've got for you from Minddrive. Minddrive, as you might remember, is the education mentorship program that "uses real-world issues of our times to teach urban students critical thinking, creativity, entrepreneurship and how to improve their future by expanding their vision for themselves." The focus was on a fully restored 1972 Volkswagen Karmann Ghia. Well, restored and converted to electric power. The students previously worked on the Lola EV but this year the focus was on a fully restored 1972 Volkswagen Karmann Ghia. Well, restored and then converted to electric power. In early June, almost 50 Minddrive students and mentors flew from Kansas City to California to visit the epicenter of electric vehicles in the US on something called the "Raise Your Hand Tour." Filmmakers Mark Honer and Kelly Creech from DHTV Digital were along for the ride. The videos below show the students flying from to Oakland, crossing the Golden Gate Bridge, presenting the Karmann Ghia at the California Academy of Sciences and then visiting the Monterey Bay EV Club, Google, Twitter and Telsa. All of this EV engagement apparently worked. One of the students, identified only as Xavier, wrote a poem and essay about what the electric vehicle project meant to him. Here's a tease: "Minddrive has honestly opened my eyes to sights and things I would have never thought possible. I have finally found the right path to follow."
