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 VW Sport Coupe GTE Concept promises exciting things for brand's future [w/video]

In recent years, it seems as though the Audi allotment of design talent from the Volkswagen Group has gotten braver, while the VW designers have become more conservative. One look at the current Volkswagen range reveals a lot of tidy sheet metal, but hardly any that rank as evocative or emotionally compelling. If the rhetoric around this Sport Coupe GTE Concept turns to action, however, VW's mass-marketed cars could become a lot more interesting to look at. Sharp creases and bold graphics can be found on just about every inch of the concept, and the large wheels at either extreme corner help to sell this as a "four-door coupe" more than most executions of that now hackneyed styling term. And, if you like what you see, then you might want to hold out for quickly approaching versions of this look on production models. Design head Walter de Silva says this language will be "shaping the immediate future" for VW product. Mechanically, the Coupe also previews more hybridization for the VW line. The concept has a plug-in hybrid powertrain, with a turbo 3.0-liter V6 driving the front wheels, and an electric motor sending yet more power to the rear. You can read up on the details in our official post from a few days ago, or just click through the pretty pictures in the gallery above. SPORT COUPE CONCEPT GTE MAKES WORLD DEBUT AT THE GENEVA AUTO SHOW Four-door coupe marks beginning of a new design era at Volkswagen Wolfsburg/Geneva, March 2015 -Volkswagen will debut the Sport Coupe Concept GTE at the 2015 Geneva International Motor Show, heralding a new and progressive Volkswagen design language. "Evolution and revolution come together in the Sport Coupe Concept GTE. This concept is based on Volkswagen design DNA, which has been visibly sharpened even more. It shows how the highest-volume brand of our Group is shaping the immediate future," says Walter de Silva, Head of Design of Volkswagen AG. Dr Heinz-Jakob Neusser, Volkswagen Brand Board Member for Development, elaborates: "This breathtakingly dynamic coupe is unlike any other to appear in this class. The design of the Sport Coupe Concept GTE is an impressive alternative to the classic sedans of the B and C segments-it has the style of a sport coupe that is enriched by the functionality of a large hatchback and the interior space of a sedan." Klaus Bischoff, Head of Design of the Volkswagen Brand, adds: "The Sport Coupe Concept GTE is another milestone of expressive design.

Dyno run hints VW GTI power might be significantly underrated

Are you one of the lucky owners of the 2015 Volkswagen GTI? If yes, you should be happy, because your 210- or 220-horsepower hot hatchback might actually have more like 260 ponies under its hood. That's according to a dyno test from a vendor on, of all places, a Ford Focus ST enthusiast forum. The company is estimating a 15-percent drivetrain loss with the GTI's best result a whopping 263 horsepower and 314 pound-feet of torque at the crank. That's a tremendous difference from the 210 hp and 258 lb-ft of torque that Volkswagen claims. Of course, this is merely one dyno session on one car. We'll have to wait until more 2015 GTI owners get on the rolling road to see if Volkswagen really was as conservative about its hot hatch's output as FocusST.org claims.
