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.

Witness this insane 736-hp VW Golf immolate its front tires

There's torque steer and then there's what we'll from now on dub "The Boba," as in Boba Kettler. The German tuner has a way with the Volkswagen Golf, and the MkI example you see above has been touched with 736 horsepower - that's right, 96 more ponies than a new SRT Viper, all trying to get to ground through those two front wheels.
The 2.0-liter, 16-valve engine has an 8,800 rpm redline and is aided by a Garrett GTX3582R turbocharger shoving 50 psi through the internals. Other upgrades include a new ECU (natch) and a six-speed 'box among other treats. The rubber is Toyo R888s - street-legal competition tires. The result is enough smoke for three Chinese New Years when the lights go green. Indeed, the standing start isn't its forte, but it can apparently get from 62 miles per hour to 124 mph in five seconds.
Watch it go in the video below. And know that this isn't even Boba's best work; he's got a 900-hp MkII Golf that'll do 0-62 mph in 2.3 seconds.

Volkswagen CrossBlue previews a three-row future, diesel-hybrid power [w/video]

Volkswagen looks to be getting ready to jump into the large three-row crossover game. The automaker has officially pulled back the curtain on the CrossBlue Concept at the 2013 Detroit Auto Show.
Designers and engineers penned the machine specifically for the Canadian and US markets, and with a plug-in diesel electric hybrid drivetrain, the hulking five-door, at least in concept form, should offer substantially better efficiency than anything else on the market. The drivetrain pairs a 2.0-liter turbo diesel four-cylinder engine with two electric motors for a combined output of 305 horsepower and a ludicrous 516 pound-feet of torque. A six-speed dual-clutch gearbox handles shifting detail, while one electric motor spins the front wheels. The second motor spins the back axle independently, make the CrossBlue a through-the-road hybrid.
As a result, the crossover can pop to 60 mph in 7.2 seconds. Perhaps more impressively, the CrossBlue can whir around on all-electric propulsion for up to 14 miles at up to 75 mph. Once the diesel four kicks in, the drivetrain can yield up to 39 mpg, though Volkswagen says the hardware can hit 89 MPGe on a full charge thanks to a 9.8 kWh lithium-ion battery pack.
