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.

The super-sized Atlas isn't the three-row VW should build

In the late '50s and early '60s the Volkswagen Beetle wasn't ubiquitous in my hometown of Lincoln, Nebraska, but it came pretty damn close. Fords and Chevys dominated, but beyond the occasional MG, Triumph, or Renault the import scene was essentially a VW scene. When my folks finally pulled the trigger on a second car they bought a Beetle, and that shopping process was my first exposure to a Volkswagen showroom. For our family VW love wasn't a cult, but our '66 model spoke – as did all Volkswagens and most imports at the time – of a return to common sense in your transportation choice. As VW's own marketing so wonderfully communicated, you didn't need big fins or annual model changes to go grab that carton of milk. Or, for that matter, to grab a week's worth of family holiday. In the wretched excess that was most of Motown at the time, the Beetle, Combi, Squareback, and even Karmann Ghia spoke to a minimal – but never plain – take on transportation as personal expression. Fifty years after that initial Beetle exposure, and as a fan of imports for what I believe to be all of the right reasons, the introduction of Volkswagen's Atlas to the world market is akin to a sociological gut punch. How is it that a brand whose modus operandi was to be the anti-Detroit could find itself warmly embracing Detroit and the excess it has historically embodied? Don't tell me it's because VW's Americanization of the Passat is going so well. To be fair, the domestic do-over of import brands didn't begin with the new Atlas crossover. Imports have been growing fat almost as long as Americans have, and it's a global trend. An early 911 is a veritable wisp when compared to its current counterpart, which constitutes – coincidentally – a 50-year gestation. In comparing today's BMW 3 Series to its' '77 predecessor, I see a 5 Series footprint. And how did four adults go to lunch in the early 3 Series? It is so much smaller than what we've become accustomed to today; the current 2 Series is more substantial. My empty-nester-view of three-row crossovers is true for most shoppers: If you need three rows of passenger capacity no more than two or three times a year – and most don't – rent it forgawdsake. If you do need the space more often, consider a minivan, which goes about its three-row mission with far more utility (and humility) than any SUV.
