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.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

In wake of Volkswagen scandal, cheating may actually get easier

The three crises that rollicked the auto industry in recent months – a rising death toll related to the General Motors ignition-switch defect, the Jeep Cherokee hack and now the Volkswagen cheating scandal – all have one thing in common. Outsiders discovered the problems. In the new matter of Volkswagen rigging millions of cars to outsmart emissions tests, researchers at West Virginia University and the International Council on Clean Transportation first spotted irregularities. In the hacking of a Jeep Cherokee, it was independent cyber-security researchers Chris Valasek and Charlie Miller who found and reported cellular vulnerabilities that allowed them to control a car from halfway across the country. And lest we forget in the case of General Motors, it was a Mississippi mechanic and Florida engineer who first made connections between non-deploying airbags and faulty GM ignition switches that had been altered over time. They worked on behalf of Brooke Melton, a 29-year-old Georgia woman killed in a Chevy Cobalt. "That argument is built on a whole string of trusts, and now it is clear that we should absolutely not be trusting." - Kyle Wiens Amid the Volkswagen scandal, the role these independent third parties played in unearthing life-threatening problems is important to highlight, not only because it shines a light on the ethical indifference corporations paid to life-and-death problems of their creation. The role of the independents is noteworthy because, just as their contributions never been more relevant in protecting the driving public, they could soon be barred from the automotive landscape. Since May, a little-known but critically important process has been playing out before an office within the Library of Congress, which will soon decide whether independent researchers and mechanics can continue to access vehicle software or whether that software, which runs dozens of vehicle components, is protected by copyright law. The Digital Millennium Copyright Act criminalizes measures taken to circumvent security devices that protect copyrighted works. When the DMCA was signed into law in 1998, it was intended to protect the likes of movies from being pirated and companies from ripping off software. At the time, few had a clue that some 17 years later cars would essentially be mobile software platforms run by millions of lines of code that potentially fall under the law's jurisdiction.
