To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Which will Dieselgate hurt more, Volkswagen or US diesels?

The most damning response to the news Volkswagen skirted emissions regulations for its diesel models may have actually come from the Los Angeles Times. On Saturday, the Times published an editorial titled "Did Volkswagen cheat?" The answer was undoubtedly yes. When you can't drive down Santa Monica Boulevard without seeing an average of one VW TDI per block, the following words are pretty striking: "... Americans should be outraged at the company's cynical and deliberate efforts to violate one of this country's most important environmental laws." VW has successfully cultivated a strong, environmentally conscious reputation for its TDI Clean Diesel technology, especially in states where emissions are strictly controlled. A statement like that is like blood all over the opinion section of the Sunday paper. The effect on VW's business, even Germany's financial health, was already felt Monday when the company's shares plummeted 23 percent in morning trading. The statement on Sunday from VW CEO Dr. Martin Winterkorn says "trust" three times. That probably wasn't enough in nine sentences. Writers over the weekend have compared VW's crisis to one at General Motors 30 years ago, when it was the largest seller of diesel-powered passenger cars until warranty claims over an inadequate design and ill-informed technicians effectively pulled the plug on the technology at GM. In a sense, VW is in the same boat as GM because it has fired a huge blow into its own reputation and that of diesels in passenger cars. And just as automakers like Jaguar Land Rover, BMW and, ironically, GM, were getting comfortable with it again in the US. VW of America was already knee-deep in its other problems this year. Its core Jetta and Passat models are aging and it needs to wait more than a year for competitive SUVs that American buyers want. The TDIs were the only continuous bright spot in the line and on the sales charts. Even as fuel prices fell and buyers shunned hybrids, VW managed to succeed with diesels and show that Americans actually care about and accept the technology again. Fervent TDI supporters might actually lobby for that maximum $18 billion fine to VW. I've personally convinced a number of people to look at a TDI instead of a hybrid. Perhaps not so much for stop-and-go traffic, but I know buyers who liked the idea that a TDI drove like a normal car and wasn't packed with batteries.
