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.

Only VW, Volvo are doing enough to electrify in Europe, study says

Among major carmakers, Volkswagen and Volvo are doing enough to electrify their vehicle lineups in Europe, and the EU needs to set tougher CO2 emission limits if it wants to meet Green Deal targets, according to a climate group's study. Sales of battery electric vehicles and plug-in hybrids almost tripled last year, boosted by tighter emission standards and government subsidies. This summer, the European Union is expected to announce more ambitious CO2 targets; by 2030, the average CO2 emissions of new cars should be 50% below 2021 levels, versus the existing target of 37.5%. Volkswagen aims to have 55% group-wide BEV sales in Europe by 2030, while Swedish carmaker Volvo, owned by China's Geely says its lineup will be fully electric by then. VW ID4 front three quarter dark View 19 Photos Based on IHS Markit car production forecasts, according to the study from European campaign group Transport and Environment (T&E), Volkswagen and Volvo have "aggressive and credible strategies" to shift from fossil-fuel cars to electric vehicles. Others like Ford Motor Co have set ambitious targets, "but lack a robust plan to get there," T&E said. Ford plans an all-electric lineup in Europe by 2030. T&E said BMW, Jaguar Land Rover (JLR), Daimler AG and Toyota rank the worst as they have low BEV sales, have "no ambitious phase-out targets, no clear industrial strategy, and an over-reliance in the case of BMW, Daimler and Toyota on hybrids." JLR, owned by India's Tata Motors, says its luxury Jaguar brand will be all-electric by 2025, but has been less specific about electrification of its higher-volume Land Rover brand. BMW and Daimler have been reluctant to set hard deadlines for phasing out fossil-fuel cars. T&E said even if carmakers meet their targets, in 2030 BEV sales could be 10 percentage points below those needed to meet the EU's Green Deal — which targets net zero emissions by 2050. Rather than a 50% reduction in CO2 emissions by 2030, based on carmakers' existing production plans, the EU could set more ambitious targets, T&E said - an up to 35% reduction in CO2 emissions from new cars by 2025, around 50% by 2027 and up to 70% in 2030. "Targets need to be gradually tightened so that carmakers not only commit to phasing out fossil fuels, but develop a strategy that gets them there on time," Julia Poliscanova, T&E senior director for vehicles and e-mobility, said in a statement.

VW readying new VR6 with forced induction

Volkswagen built a stonking, narrow-angle V6 in the 1980s and 1990s that was found in three different generations of the Golf (their performance iterations, obviously), three generations of the Passat, the New Beetle, the Corrado and the Touareg, among other VWs, a spate of Audis, Seats, a Skoda, and even the Porsche Cayenne. It was a sad day when it was announced that it'd be put out to pasture.
Rejoice, though, fans of the venerable VR6, because Volkswagen has a new, modern variant in the works that, according to AutoWeek, features direct injection and can easily be fitted with forced induction. In fact, AW mentions Volkswagen insiders that claim this unit will spawn a production version of the twin-turbo V6 shown on the Design Vision GTI from this year's Wörthersee festival. That unit produced an epic 503 horsepower and 413 pound-feet of torque.
Don't expect a production unit with that level of power (although it would make a hardy RS4 powerplant), though. In reality, AutoWeek is suspecting anywhere from 340 to 450 horsepower from the new mill. When it arrives at an undisclosed date in the future, it'll likely be found in the Passat and Passat CC as well as the production version of the CrossBlue.
