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.

2015 Volkswagen GTI: Clicking, beeping, and trying to stay cool [w/video]

My first car didn't have air conditioning. Well, that's not entirely true. The car had A/C, it just didn't work. Nevertheless, I survived summer after summer of sweating behind the wheel – par for the course in a 15-year-old Mitsubishi with 235,000 miles on the odometer. But it's another thing entirely when that same experience happens in a 2015 Volkswagen GTI after just 7,000 miles of use. That's how Autoblog kicked off summer with the long-term GTI: sweating in plaid seats. The car went to Suburban Volkswagen in Troy, MI, where the technicians told me the air-con just needed a recharge (despite asking them to inspect it further). They recharged it, the air blew cold, and 48 hours later, the A/C stopped working again. (Surprise!) The problem was a leak in the compressor/condenser line, so a new one was installed, the system was charged, and now it's fixed. For real this time. Unfortunately, that second-coming happened during a road trip with editor-in-chief Mike Austin at the helm. His logbook comments are, as you'd expect, appropriately salty. "Everybody loves the GTI, right? Not quite. I drove to Toronto for a weekend. On the way home, the A/C quit working. This wasn't too much of a problem until we hit the border control line to re-enter the United States. I always pick the slow line, somehow. Thusly baked in the heat, with outside temperatures above 80, the GTI didn't cool back down for the rest of the trip. Then I learned we already fixed the A/C once." "Of course, any car on that day with a surprise A/C failure would earn my ire," Austin notes. "It just seems a little more irritating on a new car. Otherwise, yeah, this is a great car." A great car, indeed. Everyone loves spending time with the GTI. It's got plenty of power, it's quiet, it's comfortable, and it eats up highway miles. We've got just over 10,000 miles on the odometer as of this writing, and as summer carries on, many editors have requested extended periods of seat time in the GTI for weekend getaways and longer road trips. But it's still not perfect. Following the A/C fiasco, there's another, more curious problem plaguing the GTI. Every time the car starts, a weird, varied-tempo, loud clicking is heard from the dash. We think it's coming from the direction of the glovebox, and it's not the same click patten every time. Sometimes it's one or two knocks, sometimes it's several. See what I mean in the video below. Weird, right? Another trip to Suburban Volkswagen offered no help.

My year in EVs: 8 electrics that are changing the car industry

The year 2021 will go down as an inflection point in the auto industry’s transition to electric vehicles. It's when many much-anticipated models became reality. No longer sketches or sketchy prototypes, electric vehicles appeared from all corners with everything from the Lucid Air to Ford Mustang Mach-E changing how we think about transportation. I managed to drive a lot of them, and as I went through my notes, I realized IÂ’ve got a mini memoir of the seminal EVs of 2021. HereÂ’s my take on eight of them. Hummer EV Easily the most over-the-top EV I tested this year. The 1,000-hp super truck lived up to the hype with its domineering presence, stupendous power and simply being a reincarnated Hummer. I took it for a short spin on- and off-road at the General Motors Proving Grounds in Milford, Mich., and was impressed with the airy cabin, removable sky panels and expansive touchscreens. Yes, I crab walked, which felt like steering a pontoon boat, though I can see why it would be useful. Lucid Air Dream Performance The most beautiful sedan I tested all year, EV or otherwise. Unlike the futuristic Mercedes EQS — which is quite attractive — LucidÂ’s car is a blend of mid-century modern interior aesthetics and classic European exterior styling. When I walked up for my test drive, someone who IÂ’m pretty sure was comedian Jon Lovitz was sitting inside and taking it all in. As it sat in the valet of a hotel in a wealthy suburban enclave north of Detroit, the Lucid drew more attention than any of the Mercedes, Cadillacs or Lexus models passing by. The driving experience was enveloping. Starting at $169,000 for the Performance model (reservations are closed), the Lucid I sampled packed 1,111 hp and 471 miles of range. From the precise steering to the comfortable suspension, the dynamics were spot-on. It's a formidable product, and all the more impressive given itÂ’s LucidÂ’s first. Chevy Bolt EV The Bolt was the most pleasant surprise for me. It handled well, offered low-to-the-ground hot hatch dynamics and the steering was dialed-in. Adding a crossover variant for the new generation was a smart play. On a summer morning where I went to a first drive of the Ford Bronco at an off-road course, my hour-long commute in the Bolt was an enjoyable appetizer.  The Bolt was also my biggest disappointment due to its extensive recalls for fire risk. Ironically, I had the Bolt in my driveway when the initial recall went out for the previous generation (2017-19).
