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.

Volkswagen tipped to launch turbocharged Up! with 100 hp

Overseas customers enticed by the compact dimensions of the Volkswagen Up! but turned off by its diminutive 1.0-liter three-cylinder engine may be encouraged by reports that the German automaker is planning a more potent turbo version. Previewed by the GT Up! concept showcased at the 2011 Frankfurt Motor Show (pictured above), the more performance-oriented model is expected to pack the turbo three from the larger Polo, where it produces 100 horsepower channeled through a five-speed manual transmission. That may not seem like much, but it would put the existing 59- and 74-horsepower versions of the German city car to shame. That might not give it enough punch to keep pace with the upcoming Smart Fortwo Brabus (and its Renaultsport Twingo counterpart), tipped to pack as much as 130 hp, but it could stand to out-perform the existing 89-hp turbo models of both. Given that the reports are emanating from Brazil, however, it is possible that the Up! Turbo (or whatever it's ultimately called) would be limited to the South American market, if it's built at all. One thing's for sure, though: it's not likely to make it to North American showrooms anytime soon.

Volkswagen showcasing latest emergency vehicles at RETTmobil

RETTmobil may not be the top show on our calendars, but it's the top destination for police and emergency vehicles in Europe. The show opens this week in Fulda, Germany, and Volkswagen has revealed some of the vehicles it'll be presenting to first responders there this year. Leading the charge will be the new Golf Alltrack that has been set up specially as a command car, with special lighting, graphics and equipment like an accident data recorder and unique control panel. It'll be joined as well by specially equipped versions of the Passat, Tiguan and Touareg. Volkswagen Commercial Vehicles will also be on hand to showcase an Amarok pickup set up as a beach patrol car (you know, just in case Hasselhoff happens to be in town for the show), as well as a Transporter T6 van set up as an armored personnel carrier and a Crafter ambulance. Volkswagen prasentiert sich auf der RETTmobil 2015 - Golf Alltrack erstmals als Kommandowagen vorgestellt - Transporter T6 feiert Premiere als Mannschaftstransportwagen Hannover / Fulda, 4. Mai 2015 – Mit einer vielfaltigen Produktpalette prasentiert sich Volkswagen ab dem 6. Mai auf der RETTmobil 2015. Messehighlights sind der neue Volkswagen Transporter, der seine Premiere als Mannschaftstransportwagen feiert und der neue Golf Alltrack, der dort erstmals als Kommandowagen zu sehen ist. Bis zum 8. Mai konnen sich Besucher auf der internationalen Leitmesse fur Rettung und Mobilitat in Fulda uber Sonderfahrzeuge fur Rettungseinsatz und Krankentransport informieren. Am Volkswagen Messestand (Halle 3, Stand 303) prasentieren ein speziell ausgestatteter Golf Alltrack und ein Passat Variant 4Motion, das vielfaltige Leistungsspektrum der Marke Volkswagen Pkw fur den Rettungseinsatz. Beide Modelle sind als Kommandowagen aufgebaut und verfugen uber eine umfangreiche Sonderausstattung fur den Einsatz-betrieb wie etwa Digitalfunkvorbereitung, ein Sondertastenbedienfeld und eine Sondersignalanlage mit Blaulichtleuchte. Die Fahrzeuge sind ausserdem mit dem Unfalldatenspeicher UDS ausgestattet, der den Ablauf eines Ereignisses gerichtsverwertbar dokumentiert.
