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.

Rimac is reportedly close to buying Bugatti from the Volkswagen Group

Croatia-based Rimac is finalizing a deal to purchase Bugatti from the Volkswagen Group, according to an unverified report. If the rumor is accurate, the sale would propel Rimac to the top of the automotive industry, guarantee that Bugatti's future is electric, and mark the beginning of Volkswagen's efforts to divest its empire. Executives in Wolfsburg gave the deal the green light in September 2020, according to anonymous sources who spoke to British magazine Car, but the company's supervisory board hasn't approved it yet. Selling the French company isn't as simple as sending company founder Mate Rimac an email with an account number. Insiders explained Volkswagen would likely trade Bugatti and all of its assets for a significant stake in Rimac that would be transferred directly to Porsche, which already owns 15.5% of the brand. Officials hope to increase that figure to about 49%, meaning Bugatti is theoretically worth about 33.5% of Rimac, which was founded in 2009. Bugatti told Autoblog it can't comment on speculation. Mate Rimac gave us a similar answer. Rumors of a Bugatti sale have hovered around the automotive industry for several years, and they've never materialized. In theory, spinning off the brand would be relatively easy because it's not as deeply integrated into the Volkswagen Group as its sister companies. It doesn't share its W16 engine with another carmaker, for example. And yet, Car speculates Lamborghini, SEAT, ItalDesign, Bentley, and Ducati will also be sold in the coming years, leaving Volkswagen with its namesake division, Skoda, Audi, Porsche, Scania, and MAN. Volkswagen is having an estate sale to fund the development of electric, autonomous, and digital technologies. Its downsizing will send ripples through the auto industry. Porsche could move upmarket if it doesn't have to worry about stepping on Lamborghini's toes, for example. Spinoffs are always risky, so some companies may not survive if they're not bolstered by economies of scale. As of writing, there's no word on who will pick up the brands being divested under this scenario. And, keep in mind none of this is official. Volkswagen hasn't commented on the report. We'll update this developing story as more information becomes available.

VW, Rivian, Nissan, BMW, Genesis, Audi and Volvo lose EV tax credits starting tomorrow

The U.S. Treasury said Monday that Volkswagen, BMW, Nissan, Rivian, Hyundai and Volvo electric vehicles will lose access to a $7,500 tax credit under new battery sourcing rules. The Treasury said the new requirements effective Tuesday will also cut by half credits for the Tesla Model 3 Standard Range Rear Wheel Drive to $3,750 but other Tesla models will retain the full $7,500 credit. Vehicles losing credits Tuesday are the BMW 330e, BMW X5 xDrive45e, Genesis Electrified GV70, Nissan Leaf , Rivian R1S and R1T, Volkswagen ID.4 as well as the plug-in hybrid electric Audi Q5 TFSI e Quattro and plug-in hybrid (PHEV) electric Volvo S60. The Swedish carmaker is 82%-owned by China’s Zhejiang Geely Holding Group. The rules are aimed at weaning the United States off dependence on China for EV battery supply chains and are part of President Joe Biden's effort to make 50% of U.S. new vehicle sales by 2030 EVs or PHEVs. Hyundai said in a statement it was committed to its long-range EV plans and that it "will utilize key provisions in the Inflation Reduction Act to accelerate the transition to electrification." Rivian declined to comment and the other automakers could not immediately be reached for comment. Treasury also disclosed General Motors electric Chevrolet Bolt and Bolt EUV will qualify for the full $7,500 tax credit. GM said earlier it expected at least some of its EVS would qualify for the $7,500 tax credit under the new rules, including the 2023 Cadillac Lyriq and forthcoming Chevrolet Equinox EV SUV and Blazer EV SUV. Treasury said all GM EVs will qualify. Earlier, Ford Motor and Chrysler-parent Stellantis said most of their electric and PHEV models would see tax credits halved to $3,750 on April 18. Treasury confirmed the automakers' calculations. The rules were announced last month and mandated by Congress in August as part of the $430 billion Inflation Reduction Act (IRA). The IRA requires 50% of the value of battery components be produced or assembled in North America to qualify for $3,750, and 40% of the value of critical minerals sourced from the United States or a free trade partner for a $3,750 credit. The law required vehicles to be assembled in North America to qualify for any tax credits, which in August eliminated nearly 70% of eligible models and on Jan. 1 new price caps and limits on buyers income took effect.
