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.

How the Volkswagen cheating probe developed

Fallout from Volkswagen's revelation that it engaged in cheating on emissions testing continued Monday, with the company's stock falling more than 15 percent and a Congressional subcommittee announcing an investigation into the German auto giant's conduct. Both the Environmental Protection Agency and California Air Resources Board served Volkswagen with a Notice of Violation on Friday, saying the company intentionally circumvented emissions standards by using "defeat devices." Here's a look back at the agencies' emissions enforcement history and how the charges involving Volkswagen developed. August 1998 – Honda spends $267 million to settle charges it violated the Clean Air Act by disabling "misfire monitoring devices" installed on more than 1.6 million vehicles. Ford spends $7.8 million to settle a charge it violated the Clean Air Act by installing defeat devices on 60,000 Ford Econoline vans. May 2014 – Working with the International Council on Clean Transportation, researchers at West Virginia University find significantly higher in-use emissions from a 2012 Jetta and 2013 Passat and alert the EPA to their findings. November 3, 2014 – Korean automakers Hyundai and Kia agree to pay a $100 million fine for overstating the fuel economy on several of their models by as much as six miles per gallon. In announcing the fine, government officials sought to make an example of the two companies to deter further cheating. VW officials admit the vehicles were designed with a defeat device to "bypass, defeat and render inoperative elements of the vehicle emissions control systems." "This type of conduct quite simply will not be tolerated," said then-Attorney General Eric Holder. "And the Justice Department will never rest or waver in our determination to take action against any company that engages in such activities – whenever and wherever they are uncovered." December 2, 2014 – Following discussions that stemmed from West Virginia University's findings, Volkswagen agrees to initiate a recall of 500,000 cars. The company says a software update will fix the nitrous oxide trap technology and selective catalytic reduction technology causing the cars to miss emissions thresholds. May 6, 2015 – CARB wanted to see whether the software fix implemented by Volkswagen worked. Using portable emissions measurement systems, the regulatory officials found NOx emissions were still significantly higher than expected.

10 best new car deals in late September 2021

New car sales were drastically affected in 2020 due to the ongoing coronavirus pandemic, but things started to show signs of recovery toward the end of the year before really coming on strong in the early months of 2021. Now there's an ongoing shortage of microchips causing a great deal of pricing fluctuation and a limited supply of certain vehicles. That doesn't mean there aren't still great deals on new cars, though. Using data provided by TrueCar, we’ve compiled a list of some of the best automotive deals for September 2021. WeÂ’ve noted the original MSRP, the average transaction price, and the total savings in both dollars and as a percentage of the original sticker price. Basically, weÂ’ve done all the hard work for you! So now, all you need to do is compare deals, go on a few test drives, and maybe drive away in a great car (and an even better bargain).
