VW air rule violation allegations 'stunning,' $18B fine unlikely

The big automotive news today was the US federal allegations that VW quietly and illegally installed software on approximately 482,000 diesel vehicles sold in the United States so that they would not return substandard results on government emissions tests. To say the least, this is potentially a very big deal. You can read the details of the government's allegations here. The problem seems to be with the NOx trap. Sam Abuelsamid, a former AutoblogGreen editor who is now a senior research analyst at Navigant Research's Transportation Efficiencies program, told me that there were some hints that VW's diesel emissions strategy had issues a while back. The vehicles affected by today's announcement are all equipped with the 2-liter, 4-cylinder TDI, he said. They all have the lean NOx (nitrogen oxides) trap, whereas all other current modern diesels use urea to treat NOx emissions. "When VW launched those vehicles, I went to the TDI launch program in Santa Monica and asked them if they were going to put the diesel engine into the Tiguan because that would be an ideal application," he said. "They said no, because it would be too heavy. Turns out, the NOx trap was enough to meet the emissions standards in the smaller cars, but not the Tiguan. That seems to be where the problem is, in the NOx trap. All the other big VW and Audi diesels, they use urea, just like BMW and Mercedes do." Abuelsamid added that, in California, to do an emissions test, testers don't stick a probe up the exhaust, as you would suspect. Instead, they just do a visual test to make sure nothing was tampered with and then plug a scanner into the OBD-II port to read the codes. The news today basically says that the cars were programmed to send out false codes, giving readings that testers are looking for instead of what's actually going on. "That's the background, as far as I know at this point," he said. This could be "a black eye on the auto industry." - John O'Dell Speaking at the AltCar Expo in Santa Monica just hours after the news first broke this morning, Edmunds.com's John O'Dell said the Fed's allegations were "stunning." The idea that VW might have gamed the system, he said, "underscores how important EPA clean air numbers are, that a company would allegedly stoop to this to try and meet them. Obviously, people are paying attention to that sort of thing.

2016 Volkswagen Golf TDI SportWagen Review

You might think that after driving a Dodge Challenger Hellcat during the week of the Woodward Dream Cruise, seven days with a diesel-powered Volkswagen Golf SportWagen would be a letdown. You know, like following a shot of Jack Daniels with a sippy cup of Metamucil. But it ended up being perfect timing. Right at the end of my Challenger loan, I signed my name what felt like 1,241 times, handed over a very, very large check, and officially bought my first home. The SportWagen arrived on moving day, and I set about putting the longroof's hauling ability to the ultimate test, schlepping everything I own to my very first house. SportWagens, like Metamucil, can often be very good for you. The wagon's cargo area isn't dramatically bigger than the standard Golf – 30.4 cubic feet versus 22.8 – unless you fold the second row down. With the seats flat, the Golf SportWagen's advantage nearly doubles, to 66.5 cubic feet. But it's not just the extra space that makes moving things a lot easier. The rear hatch is more defined and sits atop a lower bumper. The load height is just 24.8 inches, while the tailgate opens to an aperture of 40.6 inches. It also opens high enough that your six-foot, one-inch author can stand tall below it. The load height is just 24.8 inches, while the tailgate opens to an aperture of 40.6 inches. In short, loading stuff into the back was a breeze. While you might expect the Golf SportWagen to make short work of a bunch of boxes, it was easy to add larger items into the mix. I hauled nightstands, a large desk chair, and even all four pieces of a king-size IKEA bed frame with a minimal amount of fuss. That said, Volkswagen uses nice materials in the cargo compartment of the Golf, so if you frequently move a lot of stuff, expect to see visible wear sooner rather than later. If you prefer to move people instead of things, rest easy knowing the wagon mimics the Golf hatchback's 35.6 inches of rear legroom. Moving locally meant a lot of back-and-forth trips. Between the actual move itself and the subsequent running around, I put 600 miles on the Golf SportWagen during my week-long loan. But with this car, I could have done way more and wouldn't have found cause to complain. It's the little details that make the Golf feel premium. The Golf's cabin is a great place to be.

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.
