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.

Adventures in lazy badge engineering | Autoblog Podcast #505

On this week's podcast, Mike Austin joins David Gluckman to look back at some of the less labor-intensive badge engineering the industry has seen over the years.

Volkswagen C Coupe GTE bows in Shanghai

Following the debut of the slick, semi-aggressive Sport Coupe GTE concept in Geneva, Volkswagen is bringing something a bit more grandiose to the Shanghai Motor Show. It's called the C Coupe GTE, and it points the way forward for Volkswagen's large sedans – in China, at least. The C Coupe GTE is low and long, and rides on the same Volkswagen MLB platform that underpins vehicles like the Audi A6. Volkswagen's head of design, Klaus Bischoff, says "the C Coupe GTE very clearly shows the new 'face' of top Volkswagen sedans for the first time," so get used to this design. We think it's pretty attractive, and a car like this could easily work as an upper-tier CC replacement. But don't get your hopes up too much – VW USA says this concept was "designed chiefly for the Chinese market." That's evident inside, where the C Coupe boasts a four-passenger seating configuration with luxurious accommodations for folks in back. In fact, backseat riders can share data with the driver via the car's infotainment system. "Information about the manager's appointments can be transferred via a smartphone to the infotainment system," says Volkswagen. "Parallel to this, the appointment list also serves to plan the navigation route for the day. However, the chauffeur only has specifically filtered information for the infotainment system to facilitate punctual arrival at the destination." Like other GTE-badged models, the C Coupe uses a plug-in hybrid powertrain. That means it's got a four-cylinder turbocharged gasoline engine, an electric motor, and a 14.1-kWh lithium-ion battery, all mated to an eight-speed automatic transmission. Total system output is 242 horsepower and 369 pound-feet of torque, and Volkswagen says the C Coupe can travel up to 31 miles in electric mode (at speeds up to 81 miles per hour). Hitting 62 mph takes 8.6 seconds, but when driven economically, Volkswagen says the sedan can achieve up to 102 miles per gallon (on the Euro cycle) and cruising range is a whopping 684 miles. See the C Coupe GTE for yourself in the slideshow above, and scroll down for a huge helping of information in VW's press blast. VOLKSWAGEN DEBUTS C COUPE GTE IN SHANGHAI New plug-in hybrid concept car points the way to the future of large Volkswagen sedans Wolfsburg/Shanghai, April 2015 - Volkswagen is expanding its model range at high speed and the latest show of this intent is on display at Auto Shanghai-the C Coupe GTE.
