Audi's CEO might not have known of VW emissions scheme

There's been no shortage of finger-pointing when it comes to finding people to blame for the Volkswagen diesel-emissions scandal that broke last September. One rather powerful executive, however, appears to have escaped blame. That would be Audi CEO Rupert Stadler, whose company sold about 85,000 diesel vehicles with emissions-cheating software, Reuters says, citing people familiar with the process. US law firm Jones Day questioned executives at both VW and its Audi unit and has found no evidence that Stadler was complicit with the plan, which involved programming Volkswagen-made diesel engines to produce artificially low emissions when the vehicle was being smog-tested. In Audi's case, the engine type in question was the 3.0-liter V6 diesel. Officials with both VW and its Audi unit declined to comment, according to Reuters. That engine was used for the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year, in addition to the VW Touareg and Porsche Cayenne. Audi also sold the VW Group 2.0-liter four-cylinder in the A3 from 2010 to 2013 and 2015. VW has reached an agreement with US regulators concerning that engine, which is also not connected to Stadler. Last month, German newspaper Bild am Sonntag published specifics on how the 3.0-liter diesel cheated the emissions-testing process, including records that the motor was programmed to shut of its emissions-control equipment after 22 minutes of running, or about two minutes longer than typical emissions-compliance testing. Audi said last November that it would work on a software update for the V6's emissions-control system that would be submitted to both the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA), but the VW unit hasn't reached any settlement with US regulators implying that a solution was agreed upon. Volkswagen's settlement with the EPA will cost Europe's largest automaker as much as $15 billion in the form of buybacks, lease buyouts, vehicle repairs, and investments in zero-emissions technology. VW sold about a half-million vehicles in the US that contained the so-called "cheat" software.

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.
