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.

2013 Volkswagen Beetle Turbo Convertible

Less Flower, More Power
Pardon our political incorrectness for a moment, but the Volkswagen New Beetle was, undeniably, a "chick car." There was almost nothing that the New Beetle offered to enthusiasts (of either gender), and by the end of its run, VW had even stripped all of the exciting engines from the car's lineup. Looking to resurrect some of the excitement behind the Beetle, the third generation of the iconic car ditched the cuteness when the coupe debuted for 2012, and now the 2013 Volkswagen Beetle Convertible aims to show how much fun drivers can have without a top.
Celebrating almost six and a half decades of the Beetle convertible, Volkswagen is offering a trio of distinct special editions that celebrate three of the car's most popular decades (the '50s, '60s and '70s), but as one of the unofficial cars of the 1960s, it would almost be a crime not to test this version, right? Besides, this is also the only special edition to get the turbocharged engine. While our first drive of the 2013 Beetle Convertible was in the fuel-miser TDI variation, our two-week romp in the 2013 Beetle Convertible '60s Edition came just as peak convertible weather was kicking off down in Florida.

2015 Volkswagen GTI: Driving into spring with just one regret [w/video]

If you only notice one thing in the video above, it should be this: that GTI is filthy. Yes, the grossness of winter took its toll on our long-term 2015 Volkswagen GTI, covering the Carbon Steel hatch in a mess of salt-and-slush-streaked grime. The GTI was a champ during the cold months With 225/40R18 Bridgestone Blizzak winter tires offering sure-footed grip, the hatch became a dear companion to editors slogging through unsavory weather. Front-wheel-drive cars are already pretty solid for wintertime driving, and with the added traction of these tires, the GTI plowed forward without any drama. Our biggest gripe about snowy driving involved the car's Driver Assistance Package – a $695 option that, knowing what we know now, we wouldn't have ordered. First, this option positions the front camera right in the middle of the lower grille, which looks pretty terrible. But more importantly, the system can't tell the difference between slush/snow and an actual obstacle, so it constantly feels the need to warn us that we might hit something when the camera is covered in grime. Clearing the camera off isn't a problem, but the practice grew more annoying as the season continued. The Driver Assistance Package gets you front and rear parking sensors that, honestly, we find to be a bit too sensitive. It's activated in any low-speed situation, so the car freaks out whenever you take it through a car wash, and beeps if you walk up to the rear (to, say, open the hatch) while the engine is running. And because the GTI S model doesn't get you a rear-view camera, there's no real added benefit to the noise-makers. Yes, they help while parking in tight places, but if you struggle to park a vehicle the size of a Golf with its already excellent sight lines, you've got larger problems to overcome. We have other issues with the system, too – like how the forward sensors will blink in the instrument panel to tell you you're too close to the vehicle in front of you on the road, even with a four-car-length separation between vehicles. In all, these issues just don't seem to outweigh the benefits of the safety system. To us, it's not $695 well spent. But enough complaining. Really, the Driver Assistance Package has been the only issue we've had with the GTI since its arrival in January. Now that winter has finally melted away, we've enjoyed nice, warm temperatures here in Detroit – just last week, we were took the winter tires off.
