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.

Volkswagen CrossBlue Coupe is a green fun-machine we want to drive

Think back to January's Detroit Auto Show. Those of you that are fans of the Volkswagen brand, impressed with green technology or simply fall into the "diesel geek" category, will almost certainly remember VW's CrossBlue concept with its diesel/electric hybrid powertrain, seating for seven, and somewhat awkward crossover styling. It was an impressive piece of future tech, to be sure, though it left something to be desired in the, well, desirability department.
Here in Shanghai, VW has brought along a CrossBlue Coupe concept that would seem to include most of the goodness of the original, but flavored with more sport and style this time around.
The CrossBlue Coupe makes use of the same electric drive components as the larger three-row concept: two electric motors (front and rear) powered by a 9.8-kWh lithium-ion battery. However, where the original concept made use of a TDI four-cylinder, the Coupe substitutes a 295-horsepower, direct-injection, gasoline-burning V6.

2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.
