Volkswagen Golf Wagon leaked ahead of official unveiling

Wagons ho! These three images of the upcoming Volkswagen Golf Wagon have leaked online ahead of the car's official debut, which may very well be at the Geneva Motor Show. Looking over the photos doesn't really bring any surprises - after all, this is a VW Golf with a wagon rear end grafted on, or basically what we expect next Jetta SportWagen will be.
We can only share these three images at this time, but fret not, folks. There's little doubt that all the details and images will be flowing from Volkswagen in short order. In the meantime, click on the images above to view them in high resolution.

This classic VW bus packs Porsche power

Appearances can be deceiving. The rolling embodiments of that principal we call "sleeper cars": ordinary-looking vehicles that pack a much bigger punch than you'd get by just looking at them. Take this classic VW bus, for example. Sure, it may have some racing graphics and upgraded rolling stock to tell you this isn't just any old van, but looking at it, you'd still have no idea what lies beneath the surface. That's where you'll find oily bits sourced from Porsches. And not from a 914, either. (That was as much a Volkswagen as it was a Porsche anyway.) No, this vintage 1962 VW T1 "Bulli" van packs the air-cooled, forced-induction flat-six from a 993 Turbo, driving 530 horsepower and 558 pound-feet of torque through the six-speed manual transmission from a 996 GT3 to 18-inch BBS alloys. It's the obsessive six-year project of Swiss customizer Fred Bernhard, who also used carbon fiber to cut the curb weight down to 3,300 pounds. The resulting light sleeper can top out at 143 miles per hour, in a vehicle with the aerodynamic profile of, well, a bus. It's called the T1 Race Taxi and is being showcased by Volkswagen Commercial Vehicles at the GTI-Treffen at Worthersee this year. Short of maybe the Renault Espace F1 concept, we can hardly imagine any other van we'd rather drive around the Nordschleife. Or just to pick up the kids from school.

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.
