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.

Europeans get first crack at new Golf Variant wagon

Just last week, when we brought you news of a new Volkswagen Golf variant out and testing in Europe, we had no idea we were being so literal with out description. For it seems that VW has every intention of calling its new Golf wagon, making its Geneva debut, the "Golf Variant."
Odd/interesting sobriquets taken as read then, there's a lot to like about this new small wagon from VW. The Variant will shed some 232 pounds in this generation, and will come to market with two efficient TDI engines. Volkswagen isn't giving us displacement figures for either yet, but we're told the diesels will come with outputs of 110 and 150 horsepower. The 110-hp TDI BlueMotion Varient will be good for a whopping 71.3 miles per gallon on the European cycle, when mated to the six-speed manual transmission.
The German automaker has brought along an all-wheel-drive 4Motion version of the Gold Variant to bow in Geneva, as well, and a natural gas-burning TGI BlueMotion is said to be "in the pipeline."

VW's credit ratings could take a beating

In addition to a significant drop in its share price already, Volkswagen's diesel emissions scandal is continuing to have major financial repercussions on the German automaker. According to The Detroit News, credit rating agencies like Standard & Poor's and Moody's changed their forecasts on the company to negative, and Fitch has considered doing so, as well. Volkswagen appears to have the money to cover the costs of this ordeal, but the agencies question the effect that this has in the long term. "Moody's concern, however, is that Volkswagen's alleged breach of US environment rules and, especially, the process by which that breach occurred, will have an adverse effect on its reputation and credibility within the global passenger car markets," the company wrote in a note to investors, according to The Detroit News. VW has initially set aside $7.25 billion to fix things, but the potential shakeup of top executives has caused some investor uncertainty, too. The actual costs for VW to deal with this scandal are still unknown. In the US, the Department of Justice has begun a criminal investigation, and with other automakers the government has settled for $900 million against General Motors and $1.2 billion against Toyota. Attorneys general in 29 states have started looking deeper, according to The Detroit News, and regulators in Europe, South Korea, and Canada have commenced their own probes, as well. Related Video:
