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.

Editors' Picks March 2022 | Acura RDX, VW GLI and a Rolls-Royce

This month's Editors' Picks offer a little something at every budget. We call out a performance car as cheap as the Volkswagen GLI, but the Rolls-Royce Ghost also manages to make its way on to the list. Of course, very few folks can afford a Ghost, but that doesn't change the fact that it's an engineering master class. In addition to these options, we also dive into the compact luxury SUV market, one that is bursting with choices. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in March that earned an EditorsÂ’ Pick. 2022 Acura RDX Quick take: The RDX ticks a lot of boxes for a great price. It drives better than expected, offers excellent tech, has plenty of room and even looks the part. Score: 7.0 What it competes with: Mercedes-Benz GLC-Class, BMW X3, Volvo XC60, Audi Q5, Lexus NX, Infiniti QX50, Alfa Romeo Stelvio, Genesis GV70, Porsche Macan, Jaguar F-Pace, Lincoln Corsair Pros: Value, driving dynamics, space Cons: Infotainment is polarizing, midgrade interior From the editors Road Test Editor Zac Palmer — "The RDX is a bit of a sleeper in this segment. It drives far better than many of its competitors, and it doesn't let you down in any particular area. If you were thinking of buying an entry-level option from one of the Germans, make sure you take the RDX into account, because you'll likely end up with more tech and features for an even lower price. News Editor Joel Stocksdale — "The Acura RDX is an impressive value in the small luxury SUV segment. It starts in the low $40,000 price range, and provides loads of standard convenience and safety features. Everything is packaged in a sharp and surprisingly spacious package, too. It's also nimble and has a punchy engine that makes it fun to drive. You may find some competitors that surpass it in some areas, but the Acura offers about the most for the money of anything in the segment." In-depth analysis: 2022 Acura RDX Review | Value-packed and surprisingly sporty   2022 Volkswagen Jetta GLI Quick take: The GLI offers excellent driving dynamics and great styling for someone who doesn't want a hatchback. It's pricey, but it's worth it.

Translogic 171: EV West Karmann Ghia Electric Conversion

Translogic checks out EV West, one of the world leaders in electric vehicle conversions. Host Jonathon Buckley interviews EV West owner Michael Bream and test drives a converted 1969 Volkswagen Karmann Ghia. What drives EV West to electrify classic cars may surprise some. "We're not doing this because we're the hardcore environmentalists or we're trying to save the earth," says Bream. "If we can't at least double your horsepower and torque, we won't touch the car." In fact, EV West brings a race-tested performance pedigree to back up those boasts. The company competed in the electric class at Pikes Peak, has run through the desert at Baja, and in general has successfully proved that battery-electric vehicles can compete at a high level.
