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.

2014 VW Golf brings storied hatchback's seventh generation to US

The seventh-generation Volkswagen Golf in US-specification officially debuts at the 2013 New York Auto Show. The new model is the first VW in the States to ride on the company's MQB architecture, and as such, it makes use of plenty of high-strength and ultra-high-strength steel to keep weight down. All told, the new shell is 51 pounds lighter than the outgoing generation, despite the fact that the finished car is a full 2.2 inches longer and .5 inches wider than the 2013 model.
Buyers can expect to find a base model powered by a 1.8-liter turbocharged four-cylinder engine (blue car above) with 170 horsepower and 184 pound-feet of torque. That means the powerplant delivers the same horsepower as the old naturally aspirated 2.5-liter four-cylinder while weighing less and producing seven extra pound-feet of torque. TDI (silver car above) buyers, meanwhile, will enjoy a new 2.0-liter turbo diesel four-cylinder mill. VW says the engine yields 10 more horsepower than the old lump, which means the Golf TDI now boasts 150 hp and 236 lb-ft of torque.
GTI (red car above) buyers will now get their hands on a revised 2.0-liter turbocharged four-cylinder with approximately 210 hp and 258 lb-ft of torque - Volkswagen hasn't finalized power numbers for that machine. We're happy to see that the GTI still features its trademark plaid seats. Volkswagen says the new Golf and GTI will go on sale as a 2015 model, but doesn't say when the car will actually hit dealerships.

Volkswagen Golf R Variant ready to haul ass, stuff

Volkswagen seems to be playing a cruel trick on the American automotive public at the Los Angeles Auto Show. It's displaying its sexy Golf R Variant with no clear intention of actually selling the model here. The hot wagon launches in Europe in the spring, but the automaker makes absolutely no mention of the model's prospects in the US. Hopefully, its appearance in LA at least indicates VW is considering bringing it stateside. The great thing about this wagon is that it has everything that the regular Golf R offers, but there's even more room to carry stuff. The same 2.0-liter turbocharged four-cylinder engine makes 296 horsepower and 280 pound-feet of torque with a six-speed dual-clutch gearbox and 4Motion all-wheel drive. Performance is very close, too, with the Variant R taking 5.1 seconds to get to 62 miles per hour versus the 4.9 seconds the standard R needs to read 60 mph. The two of them also have the same tech goodies like ESC Sport stability control and multiple damping modes. The real advantage to opting for the estate is its ability to carry up to 57.2 cubic feet of cargo in the back. This hot rod wagon would seem to be perfect for the family that needs to haul some extra junk in the trunk, but doesn't want to sacrifice performance. Whether the Variant R makes it to the US remains a mystery, though. Scroll down to read the specs and feel a twinge of jealousy.
