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 throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

2014 Volkswagen Beetle GSR is black and yellow, black and yellow

Way back in 1973, Volkswagen decided it was high time to take the loveable air-cooled Bug racing. No, it wasn't painted in Herbie colors - Volkswagen called its sport-tuned machine the Beetle GSR, "Gelb Schwarzer Renner" or "Yellow Black Racer." Hence, the somewhat shocking paint scheme.
VW is bringing its sporty black and yellow Beetle back for 2014, and you can see live photos of it above. It's got a 210-horsepower turbocharged 2.0-liter four-cylinder engine under the hood (that'd be the hood up front, unlike the car's forebear), and a six-speed manual or DSG automatic transmission sends those ponies to the front wheels. Note that this car's output is up 10 horses on other turbo VWs, and the Jetta GLI and Beetle Turbo for 2013. The 0-60 run takes 6.6 seconds, and top speed is limited to 130 miles per hour.
Besides the in-your-face black and yellow paint, the GSR is outfitted with a large rear spoiler and 19-inch wheels shod with 235/40 tires. The bee-like hue carries over inside, with yellow stitching on black leather. Only 3,500 will be produced, each with its own unique plaque. Pricing has not yet been announced, but you're free to read through the press release below all the same.
