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.

Automakers drop support for Trump effort against California emissions

WASHINGTON — Toyota, Fiat Chrysler (now known as Stellantis following its merger with Peugeot) and other major automakers said on Tuesday they were joining General Motors in abandoning support for former President Donald Trump's effort to bar California from setting its own zero emission vehicle rules. The automakers, which also included Hyundai, Kia, Mitsubishi, Mazda and Subaru, said in a joint statement they were withdrawing from an ongoing legal challenge to California's emission-setting powers, "in a gesture of good faith and to find a constructive path forward" with President Joe Biden. The automakers, along with the National Automobile Dealers Association, said they were aligned "with the Biden administrationÂ’s goals to achieve year-over-year improvements in fuel economy standards." Nissan in December withdrew from the challenge after GM's decision in November shocked the industry and won praise from Biden. On Monday, the Justice Department asked the U.S. Appeals Court for the District of Columbia to put the California emissions litigation on hold to "ensure due respect for the prerogative of the executive branch to reconsider the policy decisions of a prior administration." Biden has directed agencies to quickly reconsider TrumpÂ’s 2019 decision to revoke CaliforniaÂ’s authority to set its own auto tailpipe emissions standards and require rising numbers of zero-emission vehicles, as well as Trump's national fuel economy rollback. Asked to respond to the automakers' action, White House climate adviser Gina McCarthy said in a statement that "after four years of putting us in reverse, it is time to restart and build a sustainable future, grow domestic manufacturing, and deliver clean cars for America." California Governor Gavin Newsom praised the automakers on Twitter for "dropping your climate-denying, air-polluting, Trump-era lawsuit against CA" and urged them to join the voluntary framework. TALKS WITH BIDEN Separately, an industry trade group on Tuesday proposed to start talks with Biden on revised fuel economy standards that would be higher than Trump-era standards but lower than ones set during the prior Democratic administration. The Trump administration in March finalized a rollback of U.S. Corporate Average Fuel Economy standards to require 1.5% annual increases in efficiency through 2026, well below the 5% yearly boosts under the Obama administration rules it discarded.

Audi A3 diesel fails independent emissions test in Europe

The best-selling model under Volkswagen's Audi division was emitted about double the legal limits of nitrogen oxide (NOx) levels for Europe, Reuters says, citing laboratory tests overseen by the European Commission's Joint Research Center (JRC) in August. The Audi A3 was found in two tests to emit about double the legal limit of NOx, though one of the tests had the A3 within the limits when the engine was cold. An Audi spokesman told Reuters that the A3 was independently tested to have emissions levels within the legal limit and that he wasn't aware of the JRC test results. Still, the findings are another example of how Volkswagen, Europe's largest automaker, can not seem to shed the issues surrounding the diesel-emissions scandal that broke last September. VW has been fined about $19 billion for equipping diesel cars with software that cheats emissions-testing systems. About 11 million cars were affected, including about a half-million vehicles in the US. In addition reaching a $15 billion settlement with US regulatory bodies such as the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) earlier this year, VW has been fined $15 million by the South Korean government, which may impose more penalties because of allegations of false advertising. Audi is not the only VW unit to face further scrutiny. Germany's Transport Ministry and Federal Motor Transport Authority are taking a closer look at VW's Porsche division for potential emissions-cheating efforts, Bloomberg News recently reported. Additionally, the European Union is saying that at least seven of its member nations failed to provide sufficient oversight of automobiles' emissions-testing process, and may take legal action against Germany, Spain, Luxembourg, Czech Republic, Lithuania, Greece, and Great Britain, according to a separate Reuters article.
