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.

Volkswagen looking to acquire Proton, Lotus?

Let's say you're an automaker bent on world domination looking to grow your sales. That's going to have you looking at Asian markets, because that's where some of the biggest growth has been, and that's exactly what Volkswagen is doing as it considers making another run at Malaysia's Proton.
Reuters reports that Volkswagen is interested in at least a partial stake, if not a controlling interest in Lotus-parent Proton as a way to continue a production presence in the region without having to build its own factory.
Volkswagen already builds the Passat in a DRB-HICOM facility in Pekan, Malaysia, and plans are in place to build the Jetta and Polo there, as well. With both southeast Asia and its relationship with Proton figuring so importantly in Volkswagen's plans for expansion, buying into Proton can help ensure stability. Volkswagen is being tight-lipped about the whole idea, but CEO Martin Winterkorn did recently say, "it's our clear goal to continue the successful (expansion) course of past years with great dynamics and stability," which sounds an awful lot like deals are on the table to smooth the path to further growth.

VW Beetle R is one mean bug

Volkswagen's R lineup currently consists of the Golf R in North America, and the too-cool-for-school Scirocco R in Europe. It hasn't exactly been a secret as to which VW would next get the R treatment; the German manufacturer reportedly confirmed that a hotter Beetle would be coming to the US. That announcement, in August 2011, was followed up by a production-ready Beetle R Concept at the 2011 Frankfurt Motor Show.
After some wait, we're finally seeing spy shots of the Beetle R in Germany. The mule shown in the images here is wearing the R-Line bodykit, which adds sportier front and rear fascias, side skirts, dual exhausts and a not-so-subtle spoiler. Topped off with Volkswagen's traditional, five-spoke R wheels, we'd be just fine with the Beetle R coming to market as is.
Our spy photographer, though, seems to think that the production R will get even sportier sheetmetal, which we take to mean the more assertive look shown on the Frankfurt show car. Larger intakes on the front fascia, a bigger rear spoiler and vertical vents on the rear bumper could all be upcoming. Whether a production model will include the concept's polished wheels (R cars haven't traditionally embraced that look), vented hood and the quad-tipped exhausts remains to be seen.
