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.

Volkswagen kills planned 10-speed DSG

If there are two things in this wild and crazy industry that keep growing, they are the size of cars and the number of gears in their transmissions. It wasn't ten years ago that cars with six forward gears – either manually or automatically shifted – were a relative rarity. Now, there are a multitude of sub-$30,000 cars with at least a six-speed automatic. But while eight- and nine-speed automatics are becoming increasingly common, no automaker has delivered a production ten-speed automatic (which may be a good thing, considering the reception to most nine-speed gearboxes). Ford and General Motors were collaborating on one as recently as April 2013, and Hyundai has was allegedly working on one way back in 2011. Most recently, though, Volkswagen announced a ten-speed, dual-clutch automatic in November 2014. And now, less than two years later, the project has apparently been shelved. That's according to our Vegemite-loving friends at Motoring.com.au, which report that both the cost and complexity of project has proved unfeasible for VW. "In the end, we had to balance what our priorities were with our transmissions and other things are more important and more urgent," an unnamed source at the Frankfurt Motor Show told the Aussie website. The ten-speed DSG was slated for a number of three- and four-cylinder models from VAG's entire range of affordable vehicles. It was also, allegedly, to feature in the ultra-high-performance Golf R400, Motoring reports. It's unclear how its cancellation will impact the company's future projects, if VW will look elsewhere for its small-car gearboxes, of if there's another – perhaps conventional – new transmission in the pipeline. Currently, VW's highest gear-count dual-clutch is the seven-speed DSG, shown above with company CEO Martin Winterkorn.
