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.

VW confirms three-row Tiguan to be built in Mexico

Volkswagen has been toying with the idea of a three-row crossover for some time – as evidenced by the CrossBlue concept in 2013 and the Magellan concept way back in 2002. But now the German automaker is bringing it to fruition, and it's doing so right in our back yard (or across the fence, anyway). In its latest announcement, VW confirmed recent reports that it will build a new three-row Tiguan at its plant in Puebla, Mexico. It will be made alongside the Golf and Jetta at the company's largest assembly plant outside of Germany, after a billion-dollar expansion program that will encompass nearly a million more square feet of space and employ some 2,000 workers. Once production of the new Tiguan comes on full steam in 2017, the plant will be pumping out 500 of them every day to be delivered in the Americas, but also exported to markets overseas (save for China and Europe). At that point, VW will be producing 90 percent of its products for North America locally. Of course this won't be the first time Volkswagen will be producing a Tiguan. The current model was introduced in 2007 and underwent a facelift in 2011, but includes only two rows of seating and is imported to North America from factories overseas. VOLKSWAGEN DE MEXICO TO PRODUCE THE NEW THREE-ROW TIGUAN IN ITS PUEBLA ASSEMBLY PLANT Mar 9, 2015 - Investment of $1 billion at Puebla plant - US-CEO Michael Horn: Localization key to safeguard our competitive position - Start of production end of 2016 Puebla/Herndon, March 9, 2015 – Volkswagen de Mexico announced today that a three-row version of the Tiguan will be produced at its plant in Puebla, Mexico. The car will be launched to the markets in 2017. The company will invest $1 billion for the expansion and modernization of its production facilities at the Puebla plant, as well as tooling to produce auto parts at suppliers. Volkswagen de Mexico's strategy of technological upgrading, which started with the production of the new Golf on the Modular Transverse Matrix (MQB) platform, goes to the next step with the new Tiguan. "Localization has become key to safeguarding our competitive position on the global market and manufacturing the Tiguan in Mexico will bring production closer to the U.S.-market," said Michael Horn, president and CEO of Volkswagen Group of America. "It is another proof point that Volkswagen is committed to further growth in the U.S. and North American markets.

CARB found another emissions-defeating device, this time from Audi

The California Air Resources Board has discovered another emissions-cheating device on an Audi earlier this summer, reports German newspaper Bild am Sonntag. The device is different from the software found in the VW Group's diesel-powered engines, as it alters the way the cars' automatic transmission shifts. The latest device, according to Bild am Sonntag, measures how far the cars' steering wheel is being turned. If the wheel is turned less than 15 degrees, indicating that the vehicle is being tested in laboratory conditions, a program in cars with certain automatic transmissions changes the way the gearbox shifts. The change in the transmission allows the engine to produce less carbon dioxide than when driving in normal conditions. When the wheel is turned more than 15 degrees, the program automatically turns off, claims Bild am Sonntag. The paper reports that Audi took the software out of its vehicles, which was used in both diesel- and gasoline-powered vehicles in Europe and the US, earlier this May after CARB discovered the program on one of the automaker's older cars. Several engineers that were connected with the emissions-cheating device have already been suspended, reports Bild am Sonntag. As the German newspaper points out, the device, which is fitted to certain Audis with an automatic transmission, is different from the cheat devices found on the automaker's 3.0-liter TDI turbodiesel V6 engine and Volkswagen's 2.0-liter turbodiesel motor, even those were also designed to beat emissions tests. The 3.0-liter engine is found in the Audi Q7, Volkswagen Touareg, and Porsche Cayenne models. Audi didn't immediately respond to our request for a comment.
