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 Golf GTD diesel coming to US for 2016

Part of the Volkswagen Golf recipe that has helped the car sell more than 30 million units in just under 40 years is the number of variants in which the hatchback is offered. Building on that range here in the US, Automotive News is reporting that we will finally be getting the sporty Golf GTD, likely as a 2016 model. It's the GTD, you'll recall, that crosses the performance abilities of the venerable GTI with a powerful and fuel-efficient diesel engine.
After speaking with Andreas Valbuena, Volkswagen product manager for the Golf, AN not only says that the GTD will for sale in the US in a couple years, it also estimates a baseline price of around $27,000, which would place it between the current pricing for the GTI and the Golf R. The GTD is launching in Europe this summer, but we won't be getting the seventh-generation Golf in the US for another year. The news about the performance diesel model isn't entirely unexpected - VW officials have been hinting at it for at least a year now, going so far as to import a sixth-generation model for media test drives on US soil, a task we happily took them up on last year.
The Mk VII GTD uses VW's 2.0-liter TDI engine with output increased to 184 horsepower and 280 pound-feet of torque, allowing the car to sprint to 60 miles per hour in about seven seconds while returning more than 40 mpg in highway driving. We can't wait.

VW sales increase 0.6% in September despite diesel scandal

Volkswagen was spared in the month of September from posting a sales disaster, but in reality, the impending doom and gloom is likely just postponed until October. According to VW, it delivered 26,141 vehicles to its dealerships last month, which represents a 0.6-percent gain over the same period a year ago. While up, that meager increase represents the smallest uptick of all major brands in the United States, which is currently in the middle of the best vehicular sales year in the last decade. Audi, the German automaker's mainstream luxury unit, saw a bigger gain at 16.2 percent with 17,340 total units sold, thanks in large part to the popularity of its crossover models. These numbers can't totally be taken at face value, however. In 2014, Labor Day weekend was counted as part of August's sales figures; in 2015, that traditional car-buying holiday fell early in September and is therefore partly responsible for the huge increases from all brands doing business in the United States. Remember, the diesel emissions scandal didn't hit the news until September 18, which means VW was free to sell its 2.0-liter TDI engine for the majority of the month. In other words, October is going to be the real indicator of sales reckoning as it will be the first full month that the brand can't sell its popular diesel models and the first since its emissions scandal broke. Still, TDI sales were down last month. VW reports a total of 3,060 sales of vehicles equipped with TDI engines, which represents 11.7 percent of total volume. That's nearly cut in half from the TDI's year-to-date volume percentage of 20.4 percent. "We would like to thank dealers and customers for the support of the Volkswagen brand," said Mark McNabb, chief operating officer for Volkswagen of America in a statement. "Volkswagen will continue to work diligently to regain trust and confidence in our brand." It's not yet clear exactly when VW will issue a fix to make its 2.0-liter TDI engine emissions legal, or when the EPA will recertify those models for sale. Once those two things happen, dealers will again be free to sell vehicles equipped with the powertrain, but even then it remains to be seen how consumers react when the sales ban is lifted.
