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.

Recharge Wrap-up: Jaguar Land Rover talks EVs, Batteries should be modular

A new study out of Germany suggests adopting a modular approach to battery offerings in plug-in hybrid and extended range electric vehicles. Automakers could offer the same car with different battery sizes (and different costs, accordingly) to drivers depending on their driving ranges. This would optimize the total cost of ownership for various drivers better than the current approach. Developing a modular battery design and offering appropriate batteries for different customers "is the key for electric powertrains to meet customer expectations and become cost competitive against conventional technologies," according to the report from the Institute of Vehicle Concepts, German Aerospace Center.

Wolfgang Ziebart, head of product development for Jaguar Land Rover, said in an interview that its hybrid system is being tweaked for more electric power and "downsized" combustion. He also said the likely target market for EVs would be second and third vehicles, rather than primary vehicles for urban driving. Within that market, Europeans look for something smaller, while American drivers lean toward larger luxury vehicles for their second car. Ziebart uses the Tesla Model S as an example of American tastes, and compares its size to that of the Jaguar XJ. Read more at Automotive News Europe. Thailand will likely approve a Volkswagen factory as early as next week. A German newspaper suggests that Thailand's Board of Investment is set to greenlight the plant, which is planned for a site near the Port of Bangkok. Thailand is a relatively large and growing auto manufacturing country, which seeks to be a major producer of eco-friendly vehicles. The country's "Eco2" program would provide incentives to Volkswagen if it builds clean cars and meets certain production targets. Read more at Reuters. Formula E has chosen Sky Deutschland for broadcasting rights in the German market. The deal includes television rights, as well as online broadcasting. Sky Deutschland has 3.8 million subscribers in Germany and Austria. Showing the races on Germany's largest pay television provider should help generate interest for the series, particularly the Berlin ePrix - the inaugural season's penultimate race - scheduled for May 30, 2015.

Feds allege widespread Volkswagen cheating on clean-air rules

Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the federal government charged Friday. The Environmental Protection Agency issued a notice of violation to the German automaker, saying the company's software broke the law by violating two provisions in the Clean Air Act. Circumventing the standards meant affected cars emitted as much as 40 times the allowable level of certain pollutants. Both the EPA and California Air Resources Board have launched investigations. In its notice of violations, the EPA said Volkswagen officials admitted to installing and concealing what they call a "defeat device," which was designed to detect when the cars were undergoing official emissions tests – and only turn on emissions controls during that time. "Our goal now is to ensure that the affected cars are brought into compliance, to dig more deeply into the extent and implications of Volkswagen's efforts to cheat on clean air rules, and to take appropriate further action," said Richard Corey, executive officer of CARB. The allegations cover approximately 482,000 vehicles sold in the United States over the past seven years. Cars involved include diesel versions of the Jetta, Beetle, Audi A3 and Golf manufactured between the 2009 and 2015 model years. Passats manufactured for the 2014 and 2015 model years are also included. Federal officials note there is no safety danger to motorists, but the cars will be recalled for repairs. If true, Volkswagen faces a fine that could run in the hundreds of millions of dollars -- likely higher than the $300 million charge the EPA levied last November at Hyundai and Kia for exaggerating the fuel-economy in several models. The charges also put a tremendous dent into the company's plans to increase sales of its "Clean Diesel" vehicles in North America. In a written statement, Volkswagen Group of America acknowledged it had received the notices from the EPA and CARB. "VW is cooperating with the investigation; we are unable to comment further at this time," it said. Federal officials said the defeat-device software was uncovered during an independent analysis by researchers at West Virginia University, who in working with the International Council on Clean Transportation, a non-governmental organization, raised questions about emissions levels.
