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.

Ford Mustang Mach-E fails Sweden's moose test

The infamous moose test has claimed another casualty. This time it's the Ford Mustang Mach-E AWD Long Range, which was tested in an electric four-way alongside the Tesla Model Y, Hyundai Ioniq 5 and Skoda Enyaq iV (an electric utility vehicle closely related to the Volkswagen ID.4 that is sold in the United States). According to the Swedish testers at Teknikens Varld, Ford's electric car not only failed to hit the speed necessary for a passing grade, it didn't perform well at slower speeds, either. To pass the outlet's moose test, a car has to complete a rapid left-right-straight S-shaped pattern marked by cones at a speed of at least 72 km/h (44.7 miles per hour). The test is designed to mimic the type of avoidance maneuver a driver would have to take in order to avoid hitting something that wandered into the road, which in Sweden may be a moose but could just as easily be a deer or some other member of the animal kingdom elsewhere in the world, or possibly a child or car backing into the motorway. Not only is the maneuver very aggressive, it's also performed with weights belted into each seat and more weight added to the cargo area to hit the vehicle's maximum allowable carrying capacity. The Mustang Mach-E only managed to complete the moose test at 68 km/h (42.3 mph), well below the passing-grade threshold. Even at much lower speeds, Teknikens Varld says the Mach-E (which boasts the highest carrying capacity and was therefore loaded with more weight than the rest of the vehicles tested in this quartet) is "too soft in the chassis" and suffers from "too slow steering." Proving that it is indeed possible to pass the test, the Hyundai and Skoda completed the maneuver at the 44.7-mph figure required for a passing grade and the Tesla did it at 46.6 mph, albeit with less weight in the cargo area. It's not clear whether other versions of the Mustang Mach-E would pass the test. It's also unknown if Ford will make any changes to its chassis tuning or electronic stability control software, as some other automakers have done after a poor performance from Teknikens Varld, to improve its performance in the moose test.

Compact SUV Comparison: Specs, pics and reviews of every brand's crossover

Honda CR-V vs Toyota RAV4. Chevy Equinox vs Ford Escape. Mazda CX-5 vs Subaru Forester. Whichever combinations of compact crossover SUV you're considering, there's probably a comparison test or chart out there to read. Heck, you can even create a three-car comparison yourself here at Autoblog. However, if you want a bunch of that information all in one convenient place, well, here it is. Our mega comparison of specs, features and photos of compact SUV entries from every mainstream manufacturer that sells them. That includes the 2018 Chevrolet Equinox, 2018 Ford Escape, 2018 GMC Terrain, 2018 Honda CR-V, 2018 Hyundai Tucson, 2019 Jeep Cherokee (it's already on sale with notable changes from 2018), 2018 Jeep Compass, 2018 Kia Sportage, 2018 Mazda CX-5, 2018 Mitsubishi Eclipse Cross (none of Mitsu's SUVs are perfect fits for this segment, so we deemed the MEC the most competitive fit), 2018 Nissan Rogue, 2018 Subaru Forester, 2018 Toyota RAV4 and 2018 Volkswagen Tiguan. We can update this comparison as more information about 2019 models is released, most notably the Forester and RAV4. Now, there are certainly some models that are smaller (Nissan Rogue Sport) or larger (Kia Sorento) that could also be considered, but we figured it was wise to stick with those in this sweet spot of comparable size and price. We also included links to Autoblog reviews, buying guides and smaller comparisons. Engines and Transmissions With rare exception, this segment features four-cylinder power. Sometimes it's turbocharged, often its not, but standard engine outputs are generally in the same ballpark. Therefore, we'd recommend focusing on torque output, as it's what will make a difference around town or when passing, and weighing that versus fuel economy (the Chevy Equinox, GMC Terrain, Honda CR-V and Mazda CX-5 make particularly strong cases in this regard). Many drivers aren't too fond of continuously variable transmissions (CVT), either, so that's another thing to consider and note during a test drive. As you can see, several models are available with performance upgrades. Besides the Jeep Cherokee's available V6, all are more powerful turbocharged four-cylinder engines. The exception to this would be the Honda CR-V and Ford Escape, as their 1.5-liter turbo engines don't prioritize performance. Instead, they serve as overall upgrades to the base naturally aspirated engines standard on only their base trim levels (CR-V LX and Escape S).
