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.

Europeans get first crack at new Golf Variant wagon

Just last week, when we brought you news of a new Volkswagen Golf variant out and testing in Europe, we had no idea we were being so literal with out description. For it seems that VW has every intention of calling its new Golf wagon, making its Geneva debut, the "Golf Variant."
Odd/interesting sobriquets taken as read then, there's a lot to like about this new small wagon from VW. The Variant will shed some 232 pounds in this generation, and will come to market with two efficient TDI engines. Volkswagen isn't giving us displacement figures for either yet, but we're told the diesels will come with outputs of 110 and 150 horsepower. The 110-hp TDI BlueMotion Varient will be good for a whopping 71.3 miles per gallon on the European cycle, when mated to the six-speed manual transmission.
The German automaker has brought along an all-wheel-drive 4Motion version of the Gold Variant to bow in Geneva, as well, and a natural gas-burning TGI BlueMotion is said to be "in the pipeline."

Brazil contemplates safety exemption for VW Kombi as it goes out of production today [w/poll]

Brazil: the country of carnivals, indescribable beauty adjacent to abject poverty, Ayrton Senna and old Volkswagen models. Only they're not old - they're new, they're just based on old designs. The original Beetle continued production there long after it had been phased out elsewhere, but the original Kombi van has lasted much longer. That ends today, however, with the iconic VW Microbus ambling out of production on the last day of 2013.
VW kept making the van in Brazil with the original air-cooled 1.2-liter boxer four until 2005, after which the original design was updated with a 1.4-liter water-cooled engine. Today, however, it ultimately falls prey to safety regulations that mandate that all vehicles - no matter how old their design - need to have airbags and ABS, forcing Volkswagen do Brasil to cease production of the Microbus after a 56-year production run. But the latest word is that the Kombi (as it's presently known) could get a stay of execution - or at least a resurrection in short order.
According to reports, the Brazilian government is looking into granting the Type 2 Microbus an exemption from said safety regulations, reasoning that the van was designed long before the advent of airbags and ABS. If the measure goes through, the Kombi Last Edition (pictured above) could prove not to be the last at all. So what do you think, should the Microbus get an exemption from Brazilian safety regulations for nostalgia's sake? Vote in our poll below, then have your say in Comments.
