CEO says Volkswagen's buying spree is over

After adding Italian motorcycle icon Ducati to its stable and spending $5.6 billion on the rest of Porsche, Volkswagen CEO Martin Winterkorn says he's done shopping for a while.
"We have enough to do at the moment in taking our twelve brands to where we want to be," Winterkorn tells German newspaper Handelsblatt.

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.

German prosecutors investigating Audi for emissions scandal

After weeks of investigation into Volkswagen by prosecutors in Braunschweig, Germany, attorneys in Ingolstadt will also begin an examination into Audi's potential role in the emissions scandal. They reportedly received multiple criminal complaints that requested an inquiry, including one from Audi, according to Bloomberg. The prosecutors in Ingolstadt want to focus on people within the automaker that are responsible for emissions. However, the investigation is still too early in the process to identify any specific suspects. The German lawyers might also eventually combine their cases, but they remain separate for now. "Braunschweig took those parts that are clearly located at Volkswagen and asked us to keep the elements limited to Audi," a spokesperson for the Ingolstadt attorneys told Bloomberg. Audi has 2.1 million vehicles worldwide with Volkswagen Group's emissions-cheating four-cylinder diesel, including an estimated 13,000-14,000 of them in the US. The Environmental Protection Agency also recently filed a second violation notice against the 3.0-liter TDI V6 that was used in several of the company's models here, and the automaker responded with a stop sale for them. VW Group's carbon-dioxide emissions cheating in Europe also reportedly involves some Audi models. In that case, engineers admitted to artificially improving test results to achieve the cuts that the automaker requested.
