West Virginia researcher describes how Volkswagen got caught

The cheating scandal engulfing the world's largest automaker started with a road trip. In the spring of 2014, researchers from West Virginia were evaluating the tailpipe emissions of diesel cars made for the American market by European manufacturers, something never before studied in the academic realm. Excited by the prospect of breaking new ground, the team of two professors and two students wanted to gather as much data as possible. "And being academics, we went a little overboard," said Arvind Thiruvengadam, one of the students. "Being academics, we went a little overboard." Overboard included driving the cars for more miles than they needed to test and verify results. Drivers put about 1,500 miles on each of the first two cars in the study, a Volkswagen Jetta and BMW X5, along California roadways. For their final car, a Volkswagen Passat, they wanted even more mileage. So they took the car on a road trip from Los Angeles to Seattle and back again, collecting data from more than 2,000 miles of testing. The road trip was Volkswagen's undoing. When the West Virginia team returned to Los Angeles, they were befuddled by the test results. In theory, the Passat should have spewed the lowest levels of pollutants among the three cars. Equipped with the more modern selective catalytic reduction technology, the team expected to find minimal levels of nitrogen oxide. But the car, which had been certified at a California Air Resources Board facility prior to the start of the road trip, had elevated levels of NOx that were 20 times the baseline levels established beforehand. The researchers, comprised of professors Gregory Thompson and Dan Carder and students Marc Besch and Thiruvengadam, knew their on-board equipment functioned properly because, early in their research, they had double-checked its accuracy after recording sky-high NOx readings from the Jetta that showed 30 times the level of its baseline testing at the CARB facility. It was particularly noteworthy because the Jetta contained the first-generation Lean NOx Trap technology, not the more efficient SCR, yet both produced large discrepancies. The BMW, on the other hand, performed as expected. Today, Thiruvengadam is careful to say the research team never suspected Volkswagen of cheating on emissions testing, nor did the researchers report such a finding. They merely reported their findings to CARB officials who then further investigated.

Dealers, owners feel betrayed by VW scandal

Bob Rand bought his Volkswagen Passat last year for its clean emissions and high gas mileage. He liked the car so much he convinced his son and a friend to buy one, too. Now, as Volkswagen comes clean about rigging diesel emissions to pass US tests, Rand is desperately trying to sell the fully loaded model with white leather seats for $10,000 below what he paid. His sole bite has been from a man who offered $7,500 on speculation that he could resell it in Mexico. "Volkswagen was somebody that you could rely on for cutting-edge products and quality and all those things and now you find out that they're not above lying just flat out," said Rand, who plans to join a class-action lawsuit against VW. "That's probably about as bad a thing as a company can do is lie to your face when you're buying a $35,000 car." Rand's anger at the world's top-selling car company was echoed Wednesday by private dealers, auto wholesalers and owners across the US as fallout from the smog test trickery mounted. The US Environmental Protection Agency first disclosed Friday that stealth software makes VW's 2009-2015 model cars powered by 2.0-liter diesel engines run cleaner during emissions tests than in actual driving. On Wednesday, CEO Martin Winterkorn resigned and took responsibility for the "irregularities" found by US inspectors - a scandal that has wiped out billions in the company's market value and raised the possibility of criminal investigations and billions more in fines. The revelations left dealers sitting on hundreds of diesel cars they could not sell. Many also dealt with a flood of angry calls, emails and tweets from Volkswagen owners who felt betrayed because they believed they had bought a car that polluted less without sacrificing the good gas mileage and performance that comes with a diesel engine. "I think their feet should be held to the fire." - Joe DeCarolis "I think their feet should be held to the fire. I think apologies don't mean anything when something is so premeditated," said Joe DeCarolis, of Cary, NC, who owns a 2012 TDI Jetta Sport Wagon — a car he bought after careful comparison shopping for its clean emissions and good gas mileage. Dealers can't give customers good answers because Volkswagen hasn't said a whole lot, said AutoNation CEO Mike Jackson, the leader of the largest auto dealership chain in the US.

Audi CEO's Dieselgate arrest threatens fragile truce among VW stakeholders

FRANKFURT — The arrest and detention of Audi's chief executive forces Volkswagen Group's competing stakeholders to renegotiate the delicate balance of power that has helped keep Audi CEO Rupert Stadler in office. Volkswagen's directors are discussing how to run Audi, its most profitable division, following the arrest of the brand's long-time boss on Monday as part of Germany's investigations into the carmaker's emissions cheating scandal. The supervisory board of Audi, meanwhile, has suspended Stadler and appointed Dutchman Bram Schot as an interim replacement, a source familiar with the matter said on Tuesday. Schot joined the Volkswagen Group in 2011 after having worked as president and CEO of Mercedes-Benz Italia. He has been Audi's board member for sales and marketing since last September. The discussions risk reigniting tensions among VW's controlling Piech and Porsche families, its powerful labor representatives and its home region of Lower Saxony. VW has insisted the development of illegal software, also known as "defeat devices," installed in millions of cars was the work of low-level employees, and that no management board members were involved. U.S. prosecutors have challenged this by indicting VW's former chief executive Martin Winterkorn. Stadler's arrest raises further questions. Audi and VW said on Monday that Stadler was presumed innocent unless proved otherwise. Munich prosecutors detained Stadler to prevent him from obstructing a probe into Audi's emissions cheating, they said on Monday. Stadler is being investigated for suspected fraud and false advertising. Here are the main factors deciding the fate of Audi. Background: Audi's role in Dieselgate Volkswagen Group was plunged into crisis in 2015 after U.S. regulators found Europe's biggest carmaker had equipped cars with software to cheat emissions tests on diesel engines. The technique of using software to detect a pollution test procedure, and to increase the effectiveness of emissions filters to mask pollution levels only during tests, was first developed at Audi. "In designing the defeat device, VW engineers borrowed the original concept of the dual-mode, emissions cycle-beating software from Audi," VW said in its plea agreement with U.S. authorities in January 2017, in which the company agreed to pay a $4.3 billion fine to reach a settlement with U.S. regulators.
