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.

Volkswagen pushed back against Takata airbag recall

Volkswagen and Audi will recall about 850,000 vehicles in the US to replace their Takata-supplied driver side airbag inflators, but the automaker doesn't believe the safety campaign is entirely necessary. In a letter to the National Highway Traffic Safety Administration, the company pushes the agency to re-evaluate the recall's scope because the parts are allegedly safe, it claims. VW asserted in the letter, which NHTSA posted online (as a PDF) with other documents about the company's safety campaign, that the vast majority of the automaker's recalled vehicles used Takata inflators from the supplier's factory in Freiburg, Germany. Only the US-built Passat had components from Takata's plant in Mexico. VW's argues to NHTSA that its recall is unnecessary because there are no reported airbag ruptures in the German-made parts, and the plant has better quality control than Takata's factories in the US and Mexico. In addition, the Mexico-manufactured components in the Passat are also allegedly safe because they come from a time after significant upgrades to the plant to address humidity and welding concerns. "We do not believe the facts known to date support the scope as defined in the Takata defect notification," VW's letter says. To be clear, VW is not refusing the Takata recall and plans to fix the affected vehicles. Instead, this letter shows the automaker expressing an opinion that NHTSA's scope for the campaign is too broad. VW now plans to do its own analysis on the inflators to strengthen that case, according to The Detroit News. "We respectfully request that, should such results be shown, the agency work with Volkswagen and other manufacturers to revisit the scope of these recalls," the letter said. Takata's recalled inflators use ammonium nitrate as a propellant, and experts believe that long-term exposure to high humidity can make the chemical more likely to cause a rupture during airbag deployment. The spray of metal shrapnel from the exploding parts has links to at least 10 deaths. Related Video:

Happy 60th to the VW Karmann Ghia

Volkswagen's product portfolio may be as extensive these days as any other carmaker in the business. But if you still think of the original Beetle as synonymous with the brand, that's probably because a) you're old and b) the Beetle was the company's only product until the mid-50s.
Sixty years ago Wilhelm Karmann (founder of the eponymous coachbuilder) was in Paris for the auto salon and met up with Luigi Segre and his team from Carrozzeria Ghia who showed him what was essentially a "Beetle in a sports coat." A month later they showed it to Volkswagen chief Heinrich Nordhoff who, setting aside his conservative tastes, approved it for production. And so the Volkswagen Karmann Ghia was born, giving the German marque a second product line. It still used Beetle mechanicals and was built at the same Karmann factory in Onsabrück that was already assembling the Beetle Cabriolet.
It took another couple of years to put the design into production, but from 1955 to 1974, Volkswagen and Karmann built 362,601 coupes and 80,881 of the subsequent convertible that arrived in 1957. Today the Onsabrück factory is part of the VW Group, handling production of the Golf Cabriolet, XL1 and Porsche Boxster and Cayman, and with that original Karmann Ghia prototype as part of its factory collection.
