VW Golf R 400 reportedly green-lit (again)

After speaking to Volkswagen powertrain boss Dr. Heinz-Jakob Neusser at the 2015 New York International Auto Show, we uncovered that the Volkswagen Golf R 400 would be sold in the United States... if it ever made it to production at all, that is. That prerequisite looks like it's about to be fulfilled, as the same good doctor that said the super-powered GTI would come to the US has confirmed to Car that development is currently underway. This follows up on reports from late 2014 that the 400-horsepower car would make production. "We have the Golf more sporty than ever before, since we soon will have the Golf R 400 – we will do this car," Neusser told Car. "We are in fact in development of it right now." That is, we think you'll agree, splendid news. Of course, it also begs the question of when the new car will arrive. According to Car, it'll be just "a few short months," indicating that the Frankfurt Motor Show will likely host the Golf R 400's debut later this year. Whether that proves correct, though, likely won't be clear until later this summer.

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.
