Audi, Porsche ensnared in new Volkswagen cheating allegations

The scope of the Volkswagen emissions cheating scandal that has enveloped the global automaker for the past six weeks widened Monday. Now, some of the automaker's premium brands are further ensnared in the mess. Officials with the Environmental Protection Agency issued a second notice of violations Monday, accusing Volkswagen of violating the Clean Air Act by using defeat devices that circumvent emissions testing on diesel versions of certain vehicles equipped with 3.0-liter engines. Roughly 10,000 vehicles in the United States contain the illegal software, the EPA alleges. That's a far smaller number than the 482,000 vehicles affected by the first instances of cheating, which Volkswagen confessed to in September. But this latest violation alleges the cheating occurred broadly through the Volkswagen empire and includes vehicles from the Porsche and Audi brands. Audi had one model, the A3, involved in the first round of announced violations. But the brand, which has enjoyed skyrocketing sales in the US in recent years, is more extensively involved in violations announced Monday. The 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 are among the cars which contain the illegal software, which permits the cars to emit nitrogen oxide at up to nine times the allowable thresholds set in the Clean Air Act, according to the EPA. The 2015 Porsche Cayenne and '14 Volkswagen Toureg SUV are also affected. "There is clear evidence of additional violations and it's important to put Volkswagen on notice and to inform the public." - Janet McCabe. "Audi, which has been on a roll in terms of sales, reputation and image of late, now is being drawn deeper into the quagmire," said Michelle Krebs, senior analyst for Autotrader. "Previously, only the low-volume A3 was under scrutiny, but now Audi's core models are under fire." Audi officials did not respond to a request for comment Monday. In a written statement issued late Monday afternoon, a Porsche spokesperson said, "We are surprised to learn this information. Until this notice, all our information was that the Porsche Cayenne Diesel is fully compliant." Porsche said it would cooperate with authorities.

Volkswagen may soon have remedy for more cheating diesels

Nearly a half-million motorists who own Volkswagens equipped with 2.0-liter engines have known for a few weeks the company might wind up buying back their vehicles as part of a settlement surrounding the company's emissions cheating. But about 85,000 drivers who own similarly afflicted diesels with 3.0-liter engines have been stuck without a remedy. They may not be waiting much longer. Bloomberg reports that Volkswagen will soon propose a fix for vehicles, including those from Audi and Porsche, equipped with 3.0-liter engines that will include new software and a new catalytic converter for the vehicles. Discussions with federal regulators are ongoing, according to the news outlet. "We are cooperating with the regulatory agencies and working with them on an approved solution," says Audi spokesperson Mark Clothier. "Beyond that, we cannot comment on ongoing investigations." Regulators have alleged that the company's 3.0-liter engines contain "defeat devices," illegal software that allows a vehicle to detect when it's undergoing an emissions test and turn off pollution control during real-world driving. The defeat device allows these vehicles to increase emissions of nitrogen oxide up to nine times the Environmental Protection Agency's allowable threshold. Affected 3.0-liter vehicles include the 2014 Volkswagen Toureg, 2015 Porsche Cayenne and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5. Volkswagen is slated to finalize its plans for buying back the afflicted 2.0-liter cars and potentially offer those motorists "substantial compensation" for their troubles by June 21, and it's possible that a formal announcement on the 3.0-liter vehicles would come at the same time.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
