Volkswagen's emissions deception brings more scrutiny to entire industry

Volkswagen's emissions deceptions have hurt the entire auto industry's credibility with federal regulators. Days after the world's largest automaker confessed to installing software that circumvents emissions standards on approximately a half-million diesel vehicles in the United States, a top federal safety official says the company's dishonesty will force government officials to view the entire auto industry with heightened skepticism. "Your first question has to be, 'How extensive is it through the whole industry?' You don't know if it's a unique case or if other people are doing it," said Mark Rosekind, administrator of the National Highway Traffic Safety Administration. "The unfortunate part is you're not going to worry about one person. It's extended to the entire industry. If they did it, someone else could do it." "They tell you one thing, you question it." - Mark Rosekind Rosekind's agency doesn't bear responsibility in investigating the emissions cheating. That falls to the Environmental Protection Agency, which served Volkswagen with a Notice of Violation on Friday that alleged the company's diesel vehicle equipped with 2.0-liter engines contained a defeat device that allowed the cars to detect when emissions testing was taking place. In normal driving situations, the cars spewed pollution at as much as 40 times allowable thresholds. But because of the emissions cheating, NHTSA wonders if the German automaker has been cutting corners on safety standards or disingenuous on safety-related discussions. Speaking at an auto-industry event in Novi, MI, on Tuesday, Rosekind indicated no information can now be taken at face value. He used the phrase "Question assumptions" several times in discussing the case. "Of course, question assumptions means, 'Is there some other safety element there that we're now going to have to investigate?" he said. As it did in the General Motors ignition-switch probe, the Department of Justice has initiated an investigation of Volkswagen and the House Committee on Energy and Commerce announced it will hold hearings on the cheating. For NHTSA, criminal cases complicate matters. The agency core function is to regulate safety, not conduct criminal investigations. But in the early going, their investigators may be the first ones to spot wrongdoing.

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.

Tanner Foust and Scott Speed get VW internships

Tanner Foust and Scott Speed both already have quite impressive motorsport resumes. The former is a rallycross and drifting champ, and the latter counts two years in Formula One with Toro Rosso among his accomplishments. Still, it's never too late for a career change. In a humorous new ad for Volkswagen, the professional racers take on the duties of summer interns at a dealership. The commercial is timed with the kickoff of the 2015 Global Rallycross Championship season in Fort Lauderdale, FL, on May 30 and 31. Speed and Foust are both racing in Beetle GRCs for the Volkswagen Andretti Rallycross team. This year's Bug is even more potent than last year, though. It now packs a 2.0-liter turbocharged four-cylinder engine to produce 553 horsepower and 465 pound-feet of torque, versus the previous 1.6-liter turbo four with to 544 hp and 387 lb-ft. The racer can reportedly hit 60 miles per hour in just two seconds thanks in part to low gearing and all-wheel drive. One of the Andretti team Beetles might look a little different, too. Foust is sticking with his Rockstar Energy Drink sponsorship, but Speed gets an animalistic livery for Shark Week to celebrate the annual event from the Discovery Channel. Check out both of the cars in the gallery below or the ad in the video above. SCOTT SPEED TO RACE SHARK WEEK THEMED BEETLE GRC IN RED BULL GLOBAL RALLYCROSS SEASON OPENER Scott Speed and Tanner Foust will contest the Red Bull Global Rallycross Championship in Beetle GRCs, starting this weekend in Fort Lauderdale Herndon, VA — The Volkswagen Andretti Rallycross team begins its second full season of racing this weekend in Ft. Lauderdale. The team will again be battling with two Beetle GRC race cars, which debuted in the closing races of 2014. As Volkswagen enters its fourth consecutive year as a presenting sponsor of Discovery Channel's SHARK WEEK, Scott Speed will concurrently begin the Red Bull Global Rallycross season behind the wheel of the No. 41 SHARK WEEK Volkswagen Beetle GRC, wrapped for SHARK WEEK, which begins on July 5th. "My father raced with No. 41 in karts when I was younger so it's pretty special to me," said Speed. "I have only had the option to choose the No. 41 twice in my career and was able to win championships each time. Hopefully it continues to bring me luck in 2015!" New this year, the team has chosen to change the engine specification from the Beetle GRC race cars that ran in 2014.
