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.

Which car should win 2015 World Green Car of the Year?

There were three finalists for the World Green Car of the Year announced about a month ago at the Geneva Motor Show: the BMW i8, the Mercedes-Benz S 500 Plug-In Hybrid and the Volkswagen Golf GTE. With the New York Auto Show upon us and the winner scheduled to be announced tomorrow, we thought it's high time to ask our readers which one should win. There were seven other vehicles named to the finalists list: the Hyundai x35/Tucson Fuel Cell, the Volvo XC90 T8 Twin Engine, the Audi A3 Sportback E-Tron, the BMW X5 xDrive40e, the Kia Soul EV, the Nissan e-NV200 and the Opel Adam 1.0 Direct Injection Turbo ecoFLEX Start. Would you have named one of these to the top three list instead? POLL 14386429 Green BMW Mercedes-Benz Volkswagen 2015 ny auto show world green car of the year vw golf gte

Best cheap SUVs: You don't have to pay a lot to get a lot

Here's a news flash: Everything is a lot more expensive now! And that definitely goes for new SUVs, with prices that keep nudging higher and higher. Actually "nudging" might be too soft of a description for their motion. "Skyrocketing" is probably more accurate.  While higher prices and hefty interest rates have likely knocked a lot of people out of the new car market entirely, there are still quite a few cheap SUV choices. Better still, they're not terrible! Far from it, in fact. While the lowest price SUVs used to be drab, sorry affairs best left to the lots of Avis and Budget, that is definitely not the case today. Not only are there legitimately appealing cheap SUV choices, they offer genuine differences in character, capability and design. It's not just a series of anonymous boxes with different badges. Below you won't just find a simple list of the cheapest SUVs available. We are actually pointing out the best ones. They are listed from least expensive to most expensive, with none exceeding a starting price of $30,000. Most are subcompacts, but a few of our top choices in the compact SUV segment snuck on. Finally, please excuse the crummy photo quality. We sought out representative trim levels of the prices in question rather than just reusing pretty carmaker-provided photos of the most expensive trim levels. This is what the cars will actually look like. Kia Soul Why it stands out: Ample space and abundant features for the money; unique style; strong turbo engine upgrade Could be better: All-wheel drive is not available Starting Price: $21,315 Read our most recent Kia Soul Review The Kia Soul definitely didn't start off as a small SUV, and the term "crossover" is probably better applied to it. Still, what started life as an undefinable funky tall hatchback now finds itself in its third generation with numerous vehicles of similar shape and size that are dubbed "small SUV" or "small crossover." If it walks like a duck and quacks like a duck ... Call it what you will, but the Soul delivers the goods with tons of equipment and space for its price and size, an agreeable driving demeanor, and an even more powerful engine upgrade than the Kona's. We also think it's pretty cool. All of the above helped it win our subcompact SUV comparison test. Now, if there's one area where the Soul does not satisfy a typical SUV requirement, it's the lack of available all-wheel drive.
