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.

2023 Chicago Auto Show Mega Photo Gallery: See all the new cars from the show

The 2023 Chicago Auto Show played host to a number of reveals this year, and we were there to capture all of them. In traditional auto show fashion, that means you’re getting a mega gallery of galleries to flip through and see all the vehicles on the show floor. Our EditorsÂ’ Picks from the show are already out — spoiler alert, the 2024 Toyota Grand Highlander took home the prize. That said, there were other important reveals like the 2024 Volkswagen Atlas and Atlas Cross Sport and the 2024 Subaru Crosstrek. We also learned some interesting tidbits, such as the fact that VW is considering a pickup, and Jeep owners really are plugging in. To see the photos, scroll on down and start flipping through those galleries.   2024 Toyota Grand Highlander 2024 Toyota Grand Highlander View 7 Photos 2024 Volkswagen Atlas 2024 Volkswagen Atlas View 14 Photos 2024 Volkswagen Atlas Cross Sport 2024 Volkswagen Atlas Cross Sport View 7 Photos 2024 Ford Mustang Dark Horse with its carbon fiber wheels 2024 Ford Mustang Dark Horse with carbon fiber wheels View 7 Photos 2024 Chevrolet Corvette E-Ray 2024 Chevrolet Corvette E-Ray View 10 Photos Jeep Wrangler Anniversary Editions Jeep Wrangler Anniversary Editions View 3 Photos 2023 BMW XM 2023 BMW XM View 6 Photos Ram Revolution Concept Ram Revolution Concept View 6 Photos NASCAR Chicago Street Race Pace Car — Toyota Camry NASCAR Chicago Street Race Pace Car ?

Electrify Expo is an all-electrified auto show like the old days

In late July, Autoblog swung by Washington, D.C. to check out the Electrify Expo. Now in its third year of nationwide shows, the Electrify Expo calls itself “North America's largest electric vehicle festival filled with over 1 million square feet of the world's top electric brands.” At every stop, visitors can find out about, crawl around in, drive and ride just about any personal conveyance that uses a battery for propulsion. Truth be told, when the show's PR team reached out to us with an invite, we only considered going after finding out about an area showcasing battery-electric tuner cars. EV tuning is undoubtedly going to be huge—eventually—which got us curious about these early days. We figured weÂ’d brave whatever the rest of the expo was to find out whatÂ’s the equivalent of nitrous for a Tesla. See, the EV event scene is still such that one never knows if theyÂ’ll show up to a mix of science and county fairs with a few cars on display just for truth in advertising, or if theyÂ’ll show up to a parking lot with 26 cars, 10 of them locked, 10 of them homemade, and 6 guarded by promotional hires desperate to tap all your identifying info a tablet before dispensing dubious and superficial information. Which is to say, we didnÂ’t expect much. And that makes us chuffed to report: Electrify Expo is great. We hadnÂ’t been strolling the lot outside the old RFK Stadium for five minutes before thinking, “This feels like an old-school auto show!” The exclamation to that point came from a group of four who cut me off to reach the C40 Recharge in the Volvo booth, one of them exclaiming as if he were the group expert and as if his friends were deaf, “THATÂ’S THE LEAST EXPENSIVE ONE! AND ITÂ’S BEEEE-YOUUUUU-TI-FULLLLLL!” I wasnÂ’t there to judge, I was there for the enthusiasm. Automakers had built small, simple, open booths, parked cars in them, then provided visitors the kind of interactions that will do the most good for anyone wondering about or interested in an EV. We only saw two cars that were off limits, the new Volkswagen ID.Buzz and the Ford F-100 Eluminator. Volvo wouldnÂ’t let me get an espresso from their chic little trailer, either, unless I visited the EX90 Experience trailer first. Otherwise, it was a free-for-all. Tesla had a large booth full of cars. BMW had two i7s open for everyone to sit in, next to the Ford booth with that Eluminator and an unlocked Mustang Mach-E GT and F-150 Lightning showing their cooler-chest-frunk trick.
