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.

Small 3-row crossover SUVs specifications compared on paper

There's no shortage of three-row vehicles on the market for carrying seven or more people and their stuff wherever they all need to go. Just about every car company has at least one large crossover or traditional SUV with three rows of seats, and there are still plenty of minivans to pick from. But most of these vehicles are large, pricey, and frequently thirsty. Fortunately, there are still a handful of smaller crossovers that deliver 7-passenger capability in a smaller, cheaper package. We've gathered four of the small three-row set here to compare them based on space, power, fuel economy, pricing, and more. They include the very old Dodge Journey, the slightly less old Mitsubishi Outlander and Kia Sorento, and the relatively new Volkswagen Tiguan. You can see the raw numbers in the chart below, followed by a more detailed breakdown and some notes on how we like each of these vehicles. For in-depth opinions on the vehicles, be sure to check out our full reviews, and if you want to compare these with other vehicles, try out our comparison tools. Engines, transmissions and performance Interestingly, three of the four crossovers here utilize similar engines for their four-cylinder offerings. The Dodge, Kia and Mitsubishi all feature naturally aspirated 2.4-liter four-cylinder engines. Only the Volkswagen Tiguan chooses turbocharging and a smaller 2.0-liter displacement. But because of its turbocharger, the Tiguan's four-cylinder is easily the most potent, making a healthy 221 pound-feet of torque, which is more than 40 more than the Sorento, the crossover with the next most torque. The VW is also second-most powerful, just one horse behind the Sorento. The Outlander is the least powerful in the four-cylinder class. The Journey is only barely better, but it will probably feel as slow or worse thanks to its ancient 4-speed automatic. The four-cylinder Sorento and Outlander each have 6-speed automatic transmissions, and the VW has an 8-speed. The Sorento with a V6 has an 8-speed, too. View 17 Photos Moving up to the V6 class, the Outlander is once again at the bottom. It actually makes less torque than the turbo VW Tiguan. The Journey and Sorento are almost perfectly matched. The Journey makes a bit more torque; the Sorento makes a bit more power. The Journey also gets upgraded to a 6-speed automatic. Another powertrain consideration to bare in mind is whether all-wheel-drive is necessary.

Dealers, owners feel betrayed by VW scandal

Bob Rand bought his Volkswagen Passat last year for its clean emissions and high gas mileage. He liked the car so much he convinced his son and a friend to buy one, too. Now, as Volkswagen comes clean about rigging diesel emissions to pass US tests, Rand is desperately trying to sell the fully loaded model with white leather seats for $10,000 below what he paid. His sole bite has been from a man who offered $7,500 on speculation that he could resell it in Mexico. "Volkswagen was somebody that you could rely on for cutting-edge products and quality and all those things and now you find out that they're not above lying just flat out," said Rand, who plans to join a class-action lawsuit against VW. "That's probably about as bad a thing as a company can do is lie to your face when you're buying a $35,000 car." Rand's anger at the world's top-selling car company was echoed Wednesday by private dealers, auto wholesalers and owners across the US as fallout from the smog test trickery mounted. The US Environmental Protection Agency first disclosed Friday that stealth software makes VW's 2009-2015 model cars powered by 2.0-liter diesel engines run cleaner during emissions tests than in actual driving. On Wednesday, CEO Martin Winterkorn resigned and took responsibility for the "irregularities" found by US inspectors - a scandal that has wiped out billions in the company's market value and raised the possibility of criminal investigations and billions more in fines. The revelations left dealers sitting on hundreds of diesel cars they could not sell. Many also dealt with a flood of angry calls, emails and tweets from Volkswagen owners who felt betrayed because they believed they had bought a car that polluted less without sacrificing the good gas mileage and performance that comes with a diesel engine. "I think their feet should be held to the fire." - Joe DeCarolis "I think their feet should be held to the fire. I think apologies don't mean anything when something is so premeditated," said Joe DeCarolis, of Cary, NC, who owns a 2012 TDI Jetta Sport Wagon — a car he bought after careful comparison shopping for its clean emissions and good gas mileage. Dealers can't give customers good answers because Volkswagen hasn't said a whole lot, said AutoNation CEO Mike Jackson, the leader of the largest auto dealership chain in the US.
