VW agrees to halt next-gen rally car development to help others stay in WRC

Volkswagen has petitioned the FIA to hold on to the current specifications for cars in the World Rally Championship, according to Autosport.com. The move is evidently an effort to keep as many competitors in the sport as possible, despite the fact that using the current spec racers may actually hurt Volkswagen's chances at winning. The three factory teams currently competing in the WRC are at the end of a three-year homologation cycle at the end of 2013, and new cars are expected to bow next year. But developing new racers could cost as much as $4.7 million.
That price tag would put M-Sport (which fields Ford racers) out of the WRC game for 2014 and would put Citroën participation in question as well. VW has already begun work on the next iteration of its Polo R WRC, and the hatch has nabbed four wins in six rounds this season. Now it appears that car won't bow until at least 2015. The FIA has officially agreed to freeze homologation of new WRC cars until the end of next season.

Did Lexus make a BMW? Or did BMW make a Lexus? This and other 2017 surprises

It's that time of year again. The calendar is about to reach its end, Star Trek Cats 2018 is about to take its place, and I'm reflecting about all the cars that graced my driveway this year or summoned me to exotic places. You know, like Stuttgart or Phoenix. In 2017, I drove at least 57, and as I perused the list of them, I started to notice a common refrain: "This car surprised me." Most were pleasant surprises, but there were a few head scratchers and facepalms for good measure. In both cases, it was generally the result of car companies seemingly trying to break out of an existing mold. Nowhere was that more apparent than the pair of Lexuses slathered in Infrared paint: The LS 500 that left me this week and the LC 500 that was my favorite car of 2017. Though Lexus has been trying to shake its crusty, gold-packaged reputation for some time now, its efforts always seemed like an old man choosing Hollister to redo his wardrobe after realizing it hasn't been updated since 1987. I fell in love with the LC, genuinely floored by its near-perfect take on the GT. It's characterful in sound, appearance and tactility. It was at home in the city, in the mountain and on the open road. It was both comfortable and thrilling, and after driving the mechanically related LS 500, I can report that the LC's talents aren't an outlier. The LS 500's turbo V6 may make different noises than the LC's naturally aspirated V8, but it nevertheless invigorates the cabin when the car is placed in Sport+ mode. The steering is truly communicative, body motions are kept in miraculous check, and I absolutely forgot I was in an enormous luxury limo ... and a Lexus one at that. It was everything that the BMW 530e was not. I drove that on the exact same roads and was utterly bored the entire time. Generally doughy, lifeless steering, more distant than Planet 9. And no, the plug-in hybrid powertrain had nothing to do with that. At least it shouldn't. The Porsche Panamera S e-Hybrid I also drove this year proves that, as do the Hyundai Ioniqs, which are surprisingly adept and fun little cars regardless of what powers their wheels (Hyundai + hybrid = fun really blew me away). I would drive that Lexus LS F Sport over the BMW 5 Series any day of the week, which seems like a shocking thing to say in relation to either car. While Lexus is seemingly breaking out of its old crusty mold, BMW seems to be climbing into one.

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.
