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.

Russian auto boomtown grinds to halt over Ukraine sanctions

Thousands of auto workers have been furloughed and food prices are soaring as Western sanctions pummel the small Russian city of Kaluga and its flagship foreign carmakers, with more sanctions likely to come. The Kaluga region, 190 kilometers (120 miles) southwest of Moscow, says it has attracted more than 1.3 trillion roubles ($15 billion) in investment, mostly foreign, since 2006. But Western sanctions imposed in recent weeks after Russia sent tens of thousands of troops into Ukraine have exacerbated lingering component shortages and halted production at two flagship car plants, Germany's Volkswagen and Sweden's Volvo. A third, the PSMA Rus plant that is a joint venture between Stellantis and Mitsubishi and employs 2,000, may halt production soon due to a lack of parts, Stellantis' chief executive said last Thursday. "It is not clear what will happen. They don't give us any concrete information," said Pavel Terpugov, a welder at the PSMA Rus plant. Terpugov said he needs twice as much money to buy groceries than before the sanctions. Analysts have forecast Russian inflation could soar to 24% this year, while the economy may shrink to 2009 levels. The United States and Europe are weighing more sanctions against Russia after Ukraine accused Russian forces of civilian killings in northern Ukraine, where a mass grave was found in Bucha, outside Kyiv. Russia calls its actions in Ukraine a "special operation" and the Kremlin categorically denied any accusations related to the murder of civilians, including in Bucha. One source of hope for some in Kaluga, with its 325,000 residents, is the West may be reluctant to hurt its own companies. "Does it make sense to impose sanctions on its own plant and lose money?" said Valery Uglov, an auto mechanic at the Volkswagen plant. "Does it make sense to lose the Russian market?" "We hope to return to work as soon as possible and everyone will have confidence in the future again," Uglov said. Volkswagen, whose factory employs 4,200 people, in early March suspended operations. A spokeswoman said production remained frozen. Volvo Group, which employs over 600 people to build trucks, also suspended production. Even before the sanctions, Russian car sales had contracted from 2.8 million units from when the Volkswagen factory opened in 2007 to 1.67 million units last year, damaged by both sanctions after the 2014 annexation of Crimea and the COVID-19 pandemic.

Sunday Drive: Variety is the spice of life

If there's any one new vehicle the entire world is anxiously waiting for, it's the Jeep Wrangler. Yes, of course the iconic off-roader has a loyal following here in America, but you could plop a Wrangler pretty much anywhere on the globe and everybody will know what it is. Put simply, the redesigned 2018 Jeep Wrangler JL has big, muddy shoes to fill, and the readers of Autoblog are just as interested in the Wrangler's rebirth as anyone else. Moving along, we were fortunate enough last week to spend a bit of time in nearly every version of the venerable Volkswagen Golf all in one day. There isn't a Golf we don't like, but there's one, easily identifiable by its three-digit name, that stands above all the rest: GTI. We think it's the best Golf you can buy, even if there's an R-badged variant that slots above the GTI in VW hierarchy. Rounding out our recap are three vehicles that could hardly be more different. The 2019 GMC Sierra, which was seen wearing pretty light camouflage, is a truck. The Lamborghini Terzo Millennio – which isn't going to go on sale, ever, at any price – is a conceptual supercar. And the Honda CB1000R is a retro-themed naked standard motorcycle.
