I was very disappointed to hear about the Volkswagen emissions scandal. It turns out that for years the German automaker, which recently became the world's largest, has been defrauding regulators and customers by using software to circumvent American emissions requirements. Basically, the emissions systems on diesel VWs only become fully active when the vehicle is undergoing emissions testing, making the cars seem much cleaner than in real-world driving. This was done so that VW could advertise its "clean" diesels as having the same performance as gasoline engines while offering much better fuel economy. In other words, it was a con.
VW has issued a recall on these vehicles, and the problem will be fixed, but if you have a diesel VW you should prepare yourself for a shock. Mileage and performance will both suffer. Which is too bad. I drove my buddy's Jetta diesel wagon while I was out in Seattle and was impressed by how smooth, powerful, and generally un-diesel like it was. Too bad it was all built on a lie.
This will undoubtedly hurt VW in the American market, where they have always struggled with issues of quality and price. Ultimately I think they will weather it, but their brand and image has been tarnished. A lot of smug assholes' heads are going to explode when they find out how much pollution their "clean" diesels have been spewing into the atmosphere.
On the other hand, it's probably a great time to get a deal on a new VW!
