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.

US prepares to sue Fiat Chrysler over diesel emissions testing

NEW YORK - The Justice Department plans to file a civil lawsuit against Fiat Chrysler Automobiles NV over excess diesel emissions as early as this week if no agreement is reached with the Italian-American automaker, two sources briefed on the matter said on Wednesday. The Environmental Protection Agency in January accused FCA of illegally using undisclosed software to allow excess diesel emissions in about 104,000 cars and SUVs, the result of a probe that stemmed from regulators' investigation of rival Volkswagen AG. The EPA and California Air Resources Board have been in talks with FCA about the excess emissions and whether the agencies would approve the sale of 2017 FCA diesel models. A federal judge in California has set a May 24 hearing on a series of lawsuits filed by owners of vehicles against Fiat Chrysler and the Justice Department is expected to file its action by then if no agreement is reached. FCA said on Wednesday it believed that any litigation would be "counterproductive" to ongoing discussions with the EPA and California Air Resources Board. The company added that "in the case of any litigation, FCA US will defend itself vigorously, particularly against any claims that the company deliberately installed defeat devices to cheat U.S. emissions tests." The Justice Department took the same procedural step in early 2016 against Volkswagen, nearly four months after the German company admitted using software to emit excess diesel emissions in nearly 500,000 vehicles. The Justice Department has had an ongoing criminal investigation into FCA's conduct since last year, Reuters reported in January. The probe has turned up internal emails written in Italian and other documents about engine development and emissions issues, sources briefed on the probe said. U.S. regulators said FCA failed to disclose engine management software in 104,000 U.S. 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines. The European Commission has launched legal action against Italy for failing to respond to allegations of emission-test cheating by Fiat Chrysler in a procedure that could lead to the country being taken to court. The EPA has said the maximum possible fine against FCA could be $4.6 billion. In February, FCA said it had received requests for information and subpoenas from U.S. federal and state authorities, including the Securities and Exchange Commission, for diesel issues.

Editors' Choice: Top Five 2013 Geneva Motor Show Debuts

We've returned from a very busy week in Switzerland, and in going back over all of our 75 stories from the Geneva Motor Show, our editors have gathered up their personal favorite debuts from the European expo.
